What is the climatic norm?

11/17/2016 16:54

When it comes to the weather, it is common to compare meteorological characteristics (temperature, pressure, precipitation) with the climatic norm. For example, “the temperature background corresponds to the norm for this time”, or “the temperature background turned out to be 7–9degrees above the climatic norm. So what is the climate normal?

The concept of “norm” in statistics refers to the average value over the entire series of some indicator. In climatology, this is most often the long-term average: the average monthly or annual precipitation; average daily, monthly, annual temperature, it can also be extreme (extreme) values ​​of meteorological parameters.

Climate normal is the average value of a meteorological element, statistically obtained from a long-term series of observations in a given area.

Thus, the average daily air temperature is calculated as the average of 8 observation periods. Accordingly, the average monthly temperature is the average of 30 or 31 daily averages.

For the temperature characteristics of the past day, the deviation of the average daily temperature from the climatic norm (Δ Tday) is calculated.

If the deviation does not exceed 3 °C, then the day is considered within the normal range. A day is called cold if the absolute deviation is greater than 3 °C and less than 7 °C. If the modulo deviation is more than 7 °C, then the day is considered very cold. The same criteria apply for positive deviations: from 3 °C to 7 °C – a warm day, more than 7 °C – a very hot day. In the period from October to March, when the deviation of the average daily temperature from the climatic norm by 7 ° C for at least 5 days is called the period of abnormally cold weather. Abnormally hot weather can be observed during the warm period of the year from April to September for 5 days or more, when the average daily temperatures are 7 °C or more above the climatic norm.

If the deviation of the average monthly air temperature from the norm does not exceed 1 °C, then the month is considered within the norm. A month is called cold if the absolute deviation is greater than 1 °C and less than 4 °C. If the modulo deviation is more than 4 °C, then the month is considered very cold. The same criteria apply for positive deviations: from 1 °C to 4 °C – a warm month, more than 4 °C – a very warm month.

If the length of the series is large, then the average value, and values ​​close to it, are repeated most often. When it comes to climate, the notion of normality becomes more complex.
