METEOROLOGY.

WIND-DIRECTION.

DIURNAL

[NORW. POL. EXP.

PERIOD.

In order to find the diurnal period of the wind's direction, it is necessary to have a long series of observations for discussion. This I have sought to obtain by collecting the numbers in the last table into the three following larger groups: 1, the dark season, comprising the months of October to February, during which the sun was altogether below the horizon, or — at the beginning and the end - only a short time above the horizon, but very low; 2, the sunny season, comprising the months of April to August, in which the sun was above the horizon during 24 hours; and 3, the equinoctial months March and September, in which there was regular day and night. The following 3 Tables give the numbers belonging to these 3 groups.

WIND.

The days with sky overcast show the ordinary period very well, particularly November and March with ranges above one metre per second. The periods for the seasons give a better oversight. Plate II. (1 cm. = 1 m. p. s.). In winter there is almost no period; in spring the range with sky clear is only one half of the range with sky overcast; in summer the range with sky clear is twice as great as with sky overcast; in autumn, September excluded, the range is much greater with sky overcast than with sky clear. In the dark season there is no distinct period with sky clear. The relatively considerable amount of range with sky overcast — as great as the range with sky overcast in the sunny season — is due to the ranges of October and November. Of the equinoctial months, March has a much greater range with sky overcast than with sky clear. September is not suited for a comparison in this respect. The above tables indicate that the range of the diurnal period of the velocity of the wind is greater with a greater velocity, and vice versa. A further study of this relation seemed to me desirable, and the results of such study are set forth in the following tables. From the tables giving the velocity of the wind for each hour of observation, the days on which the mean daily velocity (v) was less than 4'5 metres per second, and the when it was above 4'5 m. p. s., were taken out. For the months of the of the Fram, the mean velocity for each of these two groups and for alternate hour, the corresponding diurnal mean, and the difference between mean and the bi-hourly means (d), were taken.

In every month and season the range is much greater with the stronger winds than with the weaker. PI. II (1 cm. = 1 m. p. s.). With the weaker winds, we have in the winter and in the dark season the minimum about noon, and the maximum at 2 a. m. This is the reverse of the general rule. The range is rather small. In the other seasons we have the minimum about 4 a. m., and the maximum about noon, with a relatively small range. With the stronger winds, the period has the ordinary run, with a minimum about 2 a. m. and a maximum about noon. We have in winter and in the dark season a range nearly as great as in the other parts of the year, and in winter even greater than in summer. The spring and the equinoctial months show the greatest range. This seems to indicate that the diurnal period of the velocity of the wind is vastly more influenced by the average velocity of the wind during the day than by the change of the radiation in the course of the 24 hours. We have seen that a smaller amount of cloud and a lower average velocity of the wind during 24 hours generally give a smaller range of the diurnal period of the velocity of the wind, and that a larger amount of cloud and a higher velocity of the wind give a greater range of the diurnal period of the velocity of the wind. We have intimated (p. 294) that the first-named conditions point to an anticyclonic, the last-named to a cyclonic state of the atmosphere. In order to verify this relation, I have calculated the mean values of the pressure of the air corresponding to the velocities of the wind

The table shows that the weaker winds correspond to a 756-1 pressure above 760 m.m., and the stronger winds to a pressure below 760 m.m.

We

know

that anticyclonic winds are as a rule the weaker, and cyclonic winds the stronger. The remarkable magnitude of the range of the diurnal period of the velocity of the wind in the dark season, has induced me to calculate the relative frequency of the different wind-directions in this season, separately for weaker and for stronger winds. The result is given in the following Table. Frequency per cent.

WIND.

All directions are found. Among the weaker winds, East is most, and West least frequent. Among the stronger winds, South-East is most, and South-West least frequent. October, strongest ESE, weakest W, NW and N. November, strongest E, weakest W. As will he seen further on, the dynamic wind-roses for the dark season give as the strongest winds NNW and SSE, and as the weakest wind E; for the sunny season, strongest wind E, weakest SSW; and for the equinoctial months, strongest winds NE, weakest E.

The frequency of the fresher winds has a diurnal period of a character similar to that of the velocity of the wind in general, as will be seen from the following Table. This Table gives the number of observed winds with a velocity of 10 metres per second and upwards, reduced to bihourly daily observations during the three years from September, 1893, to August, 1896. 2 a.m. 4 a.m. 6a.m. 8a.m. 10a.m. Noon •

The frequency of calms has a maximum

in November, and a minimum

in May. (PI. I. Calm days; 1 mm. = 1 day) It is above the mean from August to the end of the year, and below the mean from January to July. Calms are very rare as compared with cases with wind. The proportion is 18 to 982, or 1 to 55.

DYNAMIC

WIND-ROSES

Taking, for each month, the sum of the numbers expressing the velocity of the wind in metres per second, for each direction of the wind (32 points), and dividing the sum by the corresponding number of observations, we get a series of numbers representing the mean velocity of each of the winds blowing from the various points of the compass, commonly called the dynamic wind-rose, or the wind-rose for the velocity of the different winds. In order to reduce the wind-directions to 16 points, I have taken for the intermediate points half the sum of the velocities and half the number of observations, and added these halves to the sum and to the number for the adjacent 16 points; I have then added the 3 velocity-numbers and the 3 observation-numbers (weights), and divided the first sum by the last. x The following Table shows the numbers thus obtained.

1 The exact reduction is not one half, but 0.5 sec. ll'/40, or (V509S. The resulting error in the computed mean velocity is very small, the addition of 0'98 per cent affecting the denominator as well as the numerator.

METEOROLOGY.

In order to find a formula for the diurnal period of the pressure of the air for the different months, the number designated by D. f. m. in the foregoing tables have been treated by harmonic analysis. The formulae are given below. In the following table Ihe numbers D. f. m. are designated by 0, the numbers computed from the formula by G, and their difference by 0 — G. For the months in which the Fram was drifting in the ice in high latitudes, I have taken the means of 3 (or 2) years. August and September, 1893, during which the Fram sailed along the Siberian Coast, have been treaded separately.

The 24-hours Period. The angular constant At lies about 160° (max. hour 7h 20m p. m.) except in September. Its range at varies between 0.041 mm. and 0.167 mm. and has maxima in February, July and September, and minima in April, September and December. The 12-hours Period. The angle A2 oscillates around 297° (max. hour 5h 5m). The general rule, maximum at 10h and minimum at 4h, is here nearly reversed. The value of a2 has a regular annual period, with maxima in February and September, and minima in December and July. The July minimum is the lowest. This corresponds with the general rule, viz. one minimum

at

the time of the Sun's perigee and one lower minimum at the apogee. The value of a2 for the year, 0.022 mm., is rather large for the high latitude of 82°. 7.

values. The change in the geographical position of the Fram has, of course, also some influence upon the change in the pressure of the air from one year to another in the same month. The smoothed curve gives a maximum of pressure, 761.47 mm., in April, and a second maximum, 760.5 mm., in December. The lowest minimum, 758.09 mm., we find in July, and a somewhat higher minimum, 758.65 mm., in February. The mean for the year is 759.55 mm.

METEOROLOGY.

The different months do not show much regularity in the amount of the relative humidity with different winds. The means for the seasons give a clearer result. PI. VII. (1 mm. = 1 per cent.). The dryest winds are those about east, and the most humid those from south to west. The equinoctial months have minima of relative humidity at east and west-north-west, and maxima at north-east and about south. Range Minimum

An inquiry into the question as to whether there is a difference between the diurnal period of the amount of cloud with weak winds and that with strong winds, has led to the following results. The days with a wind-velocity less or more than 4'5 metres per second are the same as in the similar tables already given (pp. 299 and 478) for the diurnal period of the velocity of the wind and that of the temperature of the air.

We see from these Tables that in every month the amount of cloud is greater with the stronger winds, and less with the weaker winds. The difference is greatest in the colder months, about 3'4 from January to April, and least in September, which month has the greatest amount of cloud. The weaker winter winds and the fresher summer winds give no appreciable diurnal period of the cloudiness. The general rule is that the amount of cloud is greater during the day than during the night, and that the diurnal range is greater with the stronger winds than with the weaker. PI. VIII.

Cirro-stratus has a less regular period. In winter, summer and autumn, we find a greater amount during the day than during the night ; but in spring the period is reversed. Cirro-cumulus has a maximum of frequency at 2 p. m., and a minimum about 2 a. m. in all seasons. Strato-cumulus has a maximum in the day hours, in spring and summer a couple of hours after noon, in autumn at 10 a. m., and a minimum in the early morning hours, with a rather large range. Cumulus has a very slightly pronounced period with a maximum in the middle of the day, and a minimum at midnight. Stratus shows a maximum in the early morning hours and a minimum at noon or later in the afternoon. The range is rather large in summer and autumn.

cumulus and stratus. The Tables give the sums of cases of each of the 16 points for the whole year and for the sunny season. In the dark season and in the night, the observation of the form of clouds is very difficult and sometimes impossible. The figures for this season and for the equinoctial months are therefore not to be considered as altogether trustworthy. It is only for the sunny season that they are likely to give results of scientific interest. CIRRUS. N

PRECIPITATION. For each month of the drift of the Fram, and for each observation-hour, the sum has been taken of the numbers of cases in which rain, snow, sleet or hail have been noted. These sums, divided by the whole number of observations made at the respective hour in the month, give a fraction representing the probability of precipitation for that hour. The following Table gives the diurnal period of this probability in thousandths, or per mille. For the months from October, 1893, to February, 1894, in which the observations were made only every fourth hour, the numbers for the intermediate hours have been interpolated. The numbers are (smoothed) deviations from the diurnal means.

The most frequent winds with precipitation are southerly to south-easterly, in July and August south-westerly. The westerly winds are much less frequently attended with precipitation, and calms very seldom. Taking the number of cases in which precipitation has been observed with a certain wind in a month, and dividing this number with the number of cases in which this wind has been observed in the same space of time, we get a number which gives an expression for the probability of precipitation with that wind. The following Table shows the result of such a computation.

PRECIPITATION.

17.]

The Table and the diagrams on PL IX (1 mm. = 10 per cent.1) show that the greatest probability of precipitation belongs generally to winds from the south-eastern quadrant, but without any regular distribution in the different months. The least probability is found with winds from the north-eastern and north-western quadrants. All winds may be attended by precipitation. Calms are very seldom accompanied by precipitation. The formation of rain and snow goes on more easily and frequently with wind than in calm weather. The following Table sums up the results-. Minimum Winter . . . Spring . . . Summer . . Autumn . .

In 1895, the rainy season was rather late. Hail was observed only 5 times, viz. in 1894, June 10 and July 11, in 1895, July 6 and 7, and in 1896, March 27. Counting the number of cases in which the precipitation has lasted one day, two days, etc. (of course with interruptions during the 24 hours), and taking the means for one month, we get the numbers in the following Table.

The expedition had a rain-gauge and a snow-gauge, and observations were made with them. As may have been seen from the remarks below the Tables of observation, the snow was very often observed drifting from the ground and the observations of the snow-gauge were consequently erroneous. It is therefore of no use to discuss them. The observations made with the rain-gauge can scarcely be called satisfactory, as snow-falls occur in every month, and oftener than rain.

OF THE

[NORW. POL. EXP.

POLAR

ICE.

Professor NANSEN has sent me the following note about the observations of the temperature of the drifting polar ice made during the drift of the Fram. "I considered it very desirable that the seasonal changes in the thickness of the ice covering the Polar Sea, as well as the seasonal changes in the temperature at various depths in the ice, should be systematically investigated during the years the expedition lasted. Such systematic investigations had not, to my knowledge, previously been made, and they might evidently give very valuable results, if only satisfactory methods for the observations could be found. For measurements of the thickness of the ice, long, specially-constructed augers were used, with diameters of 2 inches (5'1 cm.) and 4 inches (lO'l cm.). The difficulty of these investigations proved to be that ice-pressure on several occasions disturbed the ice, so that the investigations could not be carried on at the same place during the whole expedition; and as the ice-floes were often of different ages, their thickness might vary a good deal, even though they were flat and not disturbed by ice-pressure. We

did not therefore

succeed in getting a continuous series of observations of the growth of the same ice-floe during the whole drift of the Fram ; but our observations, when properly worked up, will nevertheless give valuable information as to the formation of the ice and its relation to the temperature of the air.

Observations of the Temperature of the Ice at Various Depths. For these observations I had ordered 3 "earth-thermometers" from NEGRETTI & ZAMBRA, as described in their large illustrated catalogue, § 57 (p. 42. See also figs. 48, 49). The thermometers (one maximum thermometer, and one slow-action thermometer) were lowered into bore-holes in the ice;

but as they would easily stick fast there when left for some time, they were often difficult to recover, and had sometimes to be dug out. ' During an operation of this kind, one of the thermometers was broken.8 I did not therefore, on the whole, consider the above method satisfactory. After several experiments, I adopted the following method. The bulbs of some ordinary thermometers (Soderbergs sling-thermometers) used for meteorological observations were enclosed in thick lumps of paraffine-wax. These thermometers were mounted in suitable holes at the ends of round wooden rods (in a manner similar to that of bath-thermometers in their wooden mounting).

The rods were at least

20 cm. longer than the bore-holes in which they were placed, in order to give a handle by which they could easily be hauled up. The rods at several places were

—

surrounded by muffs or cuffs of reindeer-skin with thick hair in order to prevent vertical circulation of air in the bore-holes. One such muff was placed close above the

^_:j

thermometer, another

at the surface of the ice, and if

the bore-holes were deep, one or two in between. The arrangement was as shown in the figure. In cold weather,

the reindeer-hair of these muffs might freeze fast to the sides of the holes, but by a little force the rods could be torn loose. The observations met with most diffi-

1 As the bore-holes had to be fairly narrow, the thermometers would easilyi'freeze fast, or the plastic or viscous ice would often, after a few days, close round the thermometer, especially during the summer. 5 I believe this was in March, 1894, but unfortunately I have not been able to find a mention of the accident in my journals.

up, the temperature-reading was taken at once, and the rods were again put down. The depth of the observations was measured from the surface of the ice to the bulb of each thermometer. There was as a rule only very little snow round the holes, and that was much trampled down. I received the impression that the observations on the whole gave fairly trustworthy results, but one source of error is the brine contained in the ice, which was apt to fill the bottom of the holes, especially the deeper ones, even during the coldest season; during the summer all holes were filled with briny or saline water, the salinity of which, however, decreased inversely as the temperature. As this brine would come from the pores of the ice and run down to the bottom of the holes, it is possible that during winter-time, when the temperature of the ice increased from the surface downwards, brine from the upper, coldest layers of the ice might sink down to the bottom of the hole, where the temperature was much higher, and as the freezing point of this very saline brine would be lower than the temperature of the bottom of the hole, it might influence the latter, and the temperature-reading might become too low.1 In the warm season, when the temperature of the ice near the surface was higher than that lower down, the brine would naturally be less saline, and consequently lighter in the upper layers than in the deeper, as the salinity of the brine varied with the temperature of the ice: the freezing point of the brine would always be the same as that of the ice. In the lowest layers of the ice, below the depth of the minimum temperature, the temperature-reading might naturally become too low in the above manner, even in the summer. Although wood conducts heat relatively slowly, it is possible that the temperature-readings from the small depths near the surface of the ice, may have been slightly influenced in this manner, especially during the summer, when the upper ends of the rods projecting above the surface of the ice were much warmed by the radiation of heat from the sun. A still greater source of error might be due to the fact that in small depths

1 This disturbing influence of the brine might have been avoided by a water-tight iron tube, completely filling the bore-hole, and sufficiently strong to withstand the pressure of the plastic or viscous ice, but unfortunately we had no material for making such tubes, and moreover iron tubes might also have a disturbing influence upon the temperature-readings by conducting the heat. If tubes of this kind were to be used, I believe it would be better to make them of a material that conducted heat slowly, e. g. glass, if it were not too easily broken.

the heat-rays from the sun or the sky penetrating the ice and the melting water (filling the holes), would be absorbed by the dark wood enclosing the thermometers, and that thus the temperature-readings became too high. This may explain the fact that temperatures above zero centigrade were observed in depths near the surface of the ice during summer. The observations of the ice-temperatures were made by myself until the middle of April, 1894. As I then thought I had formed a fairly satisfactory method of making them, I asked Capt. S. SCOTT HANSEN to undertake them as a part of the regular meteorological observations. During 1894, and I believe until the summer of 1895, these observations were made on a flat ice-floe on the port side of the Fram. This floe was formed on a wide, open water-lane about October 27th, 1893."

Fridtjof Namen.

The thermometers used for the observations of the temperature of the ice had been compared with the standard thermometer of the Meteorological Institute before the starting of the expedition. During the drift of the Fram, they were several times compared with standards and with each other, and after the return of the expedition, the thermometers then remaining were compared with the standards of the Meteorological Institute. The corrections were found to vary somewhat with the time, and may be uncertain up to some tenths of a degree C. The circumstances did not always allow of the same thermometers being used in the same depth. The holes into which the rods with the thermometers were put down required frequent cleaning, and they very often had fluid water (brine) in their lower part, this being sometimes pumped out. The place of the thermometers was changed several times, new holes being bored on the same ice-floe or the whole system removed to a new floe. The thickness of the floe in which the thermometers stood, was not constant. The numbers noted are the following: 1894.

The two last figures refer to different floes. The observations of the temperature of the "surface" are not very trustworthy. They may give the temperature of the snow, in which the thermometers were imbedded or a temperature influenced by radiation from or towards the sky (or sun).

The above Remarks give an idea of the difficulties to which the observation of the temperature of the ice were subjected. The following Table gives the monthly means for the different years of the observed temperatures for the air, the surface of the ice, and the various depths. In order to obtain the mean temperatures for the depths of 0'4, 0'8, 1'2, 1'6 and 2'0 metres, I have calculated the missing values for each month and year by means of the formula
