1891. DAILY MEAN TEMPERATURE. 
In his comprehensive survey of tiie temperature distribution in the Russian Empire, Wild* gives 
a few general deductions, about as follows, concerning the daily march of the temperature of the air 
in the middle latitudes: 
A. The amplitude of the daily curve is determined essentially by the nature of the locality, the 
amplitude being greatest over dry and arid regions and least over marine localities. 
The least mean amplitude observed on the ocean is from i°to 20 Cent., and the greatest observed 
in deserts 170 Cent. 
For the United States the mean amplitudes of various stations for the different months of the 
year are:

It is evident from the table that the amplitude is greatest over arid dry regions and least in 
marine localities. At Winnemucca in August the amplitude is 33°.8, while for the same month at 
Galveston it is only 6°.5 Fahr., or somewhat less than one-fifth of the value at Winnemucca. Gal- 
veston is also a place where the amplitude varies but slightly, from month to month, there being but 
i° Fahr. difference between the value for July (6°.6) and that of January (5°.6). At Winnemucca 
the value tor July (29°.3) is nearly twice that of January (i5°.i), the difference amounting to i4°.2. 
Galveston, Alpena, Boston, Buffalo, Chicago. New Orleans, and Toledo may be taken as types 
ot the marine locality in which the amplitude is relatively small; and Winnemucca, Roseburgh, 
Yuma, and Santa Fe may be taken as types of the inland or continental locality, in which the 
amplitude is great. DAILY MEAN TEMPERATURE. 
It will also be seen that in all places, except San Diego, the least amplitude occurs in the winter 
months and the greatest in the summer months. San Diego is a striking exception to this general 
law. The climatic conditions in the vicinity of San Diego are remarkable in this, that during the 
winter months the isocheimals have a value equaling those of the country closely surrounding the 
northern portion of the Gulf of California, whereas the isotheral curves, showing the mean summer 
temperature distribution, are of a very different character from those on the eastern slope of the San 
Jacinto Mountains. 
B. The time of occurrence of the maximum depends upon locality. In the diurnal fluctuations 
it will be seen from the following table, showing the corrections to be applied at any hour to reduce 
to the true mean temperature, that this second of Wild’s deductions also holds, and that making 
allowance for the time of the sun's reehing the zenith and the seasonal influence, the time of occur- 
rence of the maximum temperature depends upon the locality. The maximum occurs earliest in the 
purely marine climate and latest in dry and arid regions. Over the ocean and on the coast the 
highest temperature of the day occurs between midday and 1 o’clock p. in. (in summer a little earlier 
than in winter), while in the interior of continents and particularly in deserts the maximum occurs 
between 2’and 3 p. m. (in summer somewhat later than in winter), as follows:

C. The time of the occurrence of the minimum temperature, making allowance for the season and 
the time of sunrise, is also determined by the nature of the locality. Over a purely marine locality 
the minimum occurs always a certain time (from i to 2 hours) before sunrise, and over dry and arid 
regions, in the interior of continents, and especially in deserts, almost exactly at the time of sunrise 
or a little (15 minutes) later. In the winter months, however, the time of the occurrence of the mini- 
mum is always much earlier than sunrise, and so it is only in localities with continental climates that 
the minimum occurs 111 winter about the time of sunrise, as follows:

At Winuemucca during the winter months the minimum occurs an hour before sunrise and in 
the summer months about half an hour after sunrise, whereas at Galveston or Alpena the minimum 
occurs in summer as well as winter before sunrise. 
D. The amplitude of the daily oscillation and the times of maximum and minimum temperatures 
are influenced by the environment of the locality and in particular by the elevation. Just as the 
amplitude vaiies in passing from land to sea, so will it vary in passing from the surface of the earth 
to high atmospheric strata, and we will And the maximum coming earlier and nearer the time of the 
sun’s reaching the zenith, while the minimum (but not always, however) appears to move back from 
the time of sunrise toward midnight. 
E. The amplitude of the daily oscillation, other influence being allowed for, varies somewhat 
with the latitude of the place, seeming to be less in high latitudes than in low. This influence would 
be opposed to those mentioned above, and again it is essentially modified of course by the day’s 
length, i. e., the time the sun is above the horizon. 
F. The amplitude is greatly modified by the condition of cloudiness. Lamont* has shown for 
Munich, E. Quetelett for Brussels, Rykatscheff for St. Petersburg, Jesse for Hamburg, and Angot§ 
for Paris that the amplitude on clear days is much greater than on cloudy days. This influence may 
be so effective that the influence of the day’s length may be entirely masked. 
Owing to the lack of adequate cloud observations (for only an extended and continuous series 
from self-recording instruments would be really valuable in a comparison of this nature) the relation 
between the degree of cloudiness and the variation in the daily amplitude cannot be given with any 
degree of accuracy. These few conditions seem evident: 
1st. The times of the maximum and minimum temperatures vary in the course of the year much 
more on clear than on cloudy days. For example, if the maximum temperature occur at a given place 
in January, at 2.30 p. m., in July on clear days the times of maximum may vary as much as two 
hours from this time, whereas on cloudy days the tendency is to approach closely this time. 
2d. I11 the United States the greatest amplitudes are found with the least cloudiness, e. g., Win-

or difference between the highest and lowest points of the curve of diurnal variation approaches 25° 
Falir., while at Toledo, Cleveland, and Eastport, where the mean annual cloudiness is T or slightly 
over, the mean amplitude is about one-half or less that of the first-named places. 
The following table gives the amplitude and degree of cloudiness for the different months of the 
year at different places, the cloudiness being given in tenths; thus, Cleveland, 7.35 means 7 tenths

G. Topographical features have also a marked influence on the daily amplitude, and Woeikof * 
has summarized these effects as follows: 
a. A convex land surface (such as a hill or mountain) has the effect of diminishing the daily 
amplitude, and the greater the ratio of the vertical to the horizontal dimensions the greater the 
diminution. 
b. A concave land surface (such as a valley or pass) increases the daily amplitude, but only 
increases tip to a certain ratio between the vertical and horizontal dimensions. 
c. Only a perfectly level land surface can give a normal daily amplitude. 
TRUE DAILY MEAN. 
The true daily mean temperature is the sum of the observations made each hour of the twenty- 
four divided by 24. There are but few stations, however, where such a series of observations can be 
maintained for any length of time. Recourse has, therefore, been had to combination hours, from 
* “ Lehrbuch der Meteor.” Van Bebber. Page 30. DAILY MEAN TEMPERATURE. 
which a mean very close to that of the true mean is obtained. The corrections to the various 
‘‘combination hour” methods are given further on. The best known of these means are— 
6 a. m., 2 p. m., io p. m., divided by 3. (Dove’s system.)

The first and fourth of these give means very close to the true means. The 8 a. m. and 8 p. m., 
on the ground of convenience to observers, has been discussed and the corrections given in detail, 
with also a table giving the corrections for the mean obtained from observations taken at local times 
corresponding to 8 a. m. and 8 p. 111., 75th meridian time. 
MEAN TEMPERATURES. 
Twice during the twenty-four hours occurs a mean temperature of the day. The forenoon mean 
over water surfaces occurs about 8 o’clock, and over dry and arid localities nearly an hour later. The 
evening mean, in general, occurs after sunset, and comes earlier over water surfaces than over dry 
and arid regions, and varies less in the course of the year than the morning mean. 
icoppen’s method of determining the true daily mean temperature. 
I11 the “Ann. der Hydrog.,” 1888, p. 341, and in You Bebber’s “ Lehrbuch der Meteorologie,” 
p. 34j is described a method for obtaining the true daily mean temperature from the mean of the 8 a. 
in., 2 p. m., and 8 p. m. observations in connection with the minimum. This last is not given equal 
weight with the others, but has a value varying with the month. 
Let n — mean of 8 a. 111., 2 p. 111., 8 p. m. & = minimum. m=rtrue daily mean. 
Then m = n — A; (n — b) and k = -—The correction to be applied to 8-— is propotional to the 
n 0 3 
distance of the minimum temperature from the mean. 
rnl . , . 8 a., 2 p., 8 p. 7 ( 8 a., 2 p., 8 p. . . ) 
The formula is — ’ ’ — k • —minimum > = true mean. A determination 
3*3 > 
of the value of this factor A; shows that it varies from a mean value of o°.i75 Fahr. [o°.i Cent.] in 
January to o°.22 Fahr. [0.12 Cent.] in June. 
Table I on page ix gives the values of k, and shows also very clearly the variation in this value 
with the season as well as with locality. 
This method isopen to criticism, however, in this that for general use it requires the nicest 
determination of the minimum temperature, and in the absence of self-registering instruments this 
necessitates an observation at what is apt to be an inconvenient hour. Conversely the formula sug- 
gests an interesting method of determining the true minimum when the true mean and the various 
other observations are given. 
Let i°—k = li and 7 —l Minimum temperature— 7 - h 7 =1 ( U — true mean. 
k 3 A; k \ 3 / 
TO DETERMINE THE TRUE DAILY MEAN TEMPERATURE FROM THE MAXIMUM 
AND OTHER TEMPERATURES. 
Koppen’s method, given just above, suggested the following method of getting the mean, making 
use of the maximum instead of the minimum temperatures and using the 8 a. 111. and 8 p. m. (local 
time) observations. The maximum temperature occurs at a time of day when, in the ordinary routine 
of life, an observer is able to note with convenience to himself the temperature, and in this respect, 
therefore, this method is more advantageous. 
The formula is, if we let L 1 ' maximum = c, true daily mean = d, i° Fahr.— k' = h. 
b—kf {b — c)=d, b-\-kf [c — b)—d, bh=d — A/ c, and d = b h-\- W c. 
Table II on page ix gives the values of kf and h for different places in the United States, and it DAILY MEAN TEMPERATURE. 
will be observed that in the summer months the sign of k' may be chauged and its value become a 
negative one, a partial interpretation of which is, that in these months, the 8 a. m. and 8 p. m. observa- 
tions divided by two, give a temperature very close to or a little above the true mean, where during 
the rest of the year this value is below the true mean.

Table II.— Values of K' and H. DAILY MEAN TEMPERATURE. 
The following values are based upon the observations of temperature made at the stations of the 
United States Signal Service from January, 1877, to July, 1888, covering a period of twelve years. 
These observations were carefully reduced in the office of the Chief Signal Officer, and a series of 
mean hourly values for the twelve years determined. These values were plotted, and a series of 
curves representing the mean daily march of the temperature at each station and for every month 
obtained. Thermograph records for periods of from one to three years, which furthermore had been 
carefully checked each day at different times by eye readings of the exposed thermometer, were also 
available and were given proper weight in determining the true form of the curve. The value of the 
temperature at each of the twenty-four hours of the day was then taken from the curve and the true 
daily mean temperature obtained by dividing the sum of the twenty-four by 24. For a large number 
of stations, as will be evident, these corrections have been worked out in full, but where interpolated 
values occur they have been obtained by determining first the average values of corrections for that 
time and locality, the hours at which the mean temperatures would occur, the times of maximum and 
minimum temperatures and their departures from the mean, and finally by comparison with a station 
in the vicinity, for which actual values had been worked out. In all cases where not otherwise stated 
local time has been used as the standard. 
It further remains for me to acknowledge my indebtedness to General A. W. Greely, Chief 
Signal Officer. In its aim and scope this paper rightly belongs to him. He suggested most, if not 
all, of the methods employed, and daily gave the work, while in progress, his personal supervision 
and criticism.
