To calculate the average monthly temperature air (low temperature indicator for a particular month), add up all the daily average values.
In calculating the average daily air temperature spend several dimensions.Type used in this thermometer will depend on your goals.Regular alcohol thermometer is better to check for reference, since alcohol devices have become outdated.Mercury instrument to use is not recommended in winter, when severe frosts it can fail.
grading scale will depend on the requi
red accuracy.Common alcohol thermometer has a precision of one degree.If imposed relatively high requirements for the determination temperature, use the device with finer grading, available indicators of hundredths or thousandths of a degree.
to experiment in the warm season, make sure that the thermometer is in the shade.Terms of observations should be the same, otherwise you can not avoid mistakes.Write down in a diary of observations of the thermometer in the morning, at lunch, in the evening, at midnight.Fold them, divide by 4 (number of observations).
Fold positive and negative numbers, just as always.For example, if the night thermometer -2 ° C, and in the daytime + 4 ° C, divide by the number of observations in the value of + 2 ° C.
Once you obtain and add up all the daily mean air temperature for the month, divide the resulting amount by the number of days in it (30, 31, 28 or 29).
Round the resulting number to the value of the accuracy that you need (often enough tenths, but sometimes it may be necessary hundredths and even thousandths).By the same token, you can calculate the monthly average daytime and nighttime temperatures in isolation from each other.
average monthly temperature of the water is determined by the same principle as the air.The only difference is applied instrumentation.
