Annual mean temperature

from Wikipedia, the free encyclopedia

The annual mean temperature of a location, also known as the annual mean temperature , is calculated from the average of the twelve monthly mean temperatures . In principle, the specification of mean values ​​without a measure of dispersion is only meaningful to a limited extent. Information on both day-night amplitudes and variance over the years of the survey period is desirable . 30 years of measurements by a weather station are considered sufficient to achieve a stable value for the annual mean temperature.

Forestry and Biology

In forestry and biology , the annual mean temperature in the vegetation period is often determined to characterize a forest area .

The warmest and coldest monthly mean temperatures are often decisive for whether a plant species can thrive in one location. The tropical tree coconut palm cannot tolerate it when the mean temperature of the coolest month is below 20 degrees.


The annual mean temperature and the highest and lowest monthly mean temperatures are also used to characterize and differentiate between different types of climate .

Global warming

An average annual mean temperature for the entire earth is calculated from the results of many weather stations distributed around the world. Here, one is global warming observed. According to the Intergovernmental Panel on Climate Change (IPCC), the average global temperature increase between 1880 and 2012 is 0.85 ° C.

Influence on productivity

In a study, the importance of different location factors for the total factor productivity of a region was examined using data from 257 regions of the EU. Numerous influencing properties of the regions were taken into account for the analysis. A high annual average temperature had a negative impact on productivity.
