REMARKS --- |
|
|
|
|
|
|
|
|
|
|
|
|
|
Unless otherwise noted, all 1878 data are from fixed time observations taken daily at the Ft. Snelling |
|
|
|
|
|
|
|
|
|
|
|
|
|
post hospital station at 0700, 1400 and 2100 hours local time. So far as can be determined, the station was |
|
|
|
|
|
|
|
|
|
|
|
|
|
not equipped with self-registering maximum-minimum thermometers at any time during 1878. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Foregoing average temperatures include the averages of fixed time observations taken at 0700 and 1400 hours. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Average monthly temperatures were calculated by taking the sum of the daily 0700 hour and 1400 hour readings |
|
|
|
|
|
|
|
|
|
|
|
|
|
plus twice the sum of the 2100 hour readings and dividing the resulting sum by four. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Extreme maxima and extreme minima are the highest and lowest values OBSERVED at the Ft. Snelling station |
|
|
|
|
|
|
|
|
|
|
|
|
|
during the month involved. Monthly average temperatures have NOT been adjusted to the NWS 2400-2400 hour |
|
|
|
|
|
|
|
|
|
|
|
|
|
observation day. Highest 1878 observed temperatures were recorded at 1400 hours on 15, 16 July and 5 September. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Monthly mean cloudiness values are the averages based on visual sky cover observations taken daily at 0700, |
|
|
|
|
|
|
|
|
|
|
|
|
|
1400 and 2100 hours local time. A cloudiness value of zero (0) indicates a totally clear sky: a value of five indicates |
|
|
|
|
|
|
|
|
|
|
|
|
|
50 percent cloud cover, etc. Greatest daily precipitation recorded on 25 July. |
|
|
|
|
|
|
|
|
|
|
|
|
|
November 1878 precipitation value is probably a combination of unmelted snowfall and meltwater data. |
|
|
|
|
|
|
|
|
|
|
|
|
|
Lowest 1878 temperature recorded at 0700 hours on 6 January and 23 December. |
