§ Annual rainfall in Germany

Annual rainfall in Germany in 2020: 705 l/m2

§ How is rainfall measured and estimated?

In Germany, the amount of rainfall is indicated in liters per square meter (l/m2), which exactly corresponds to millimeters of precipitation (mm). This value means the amount of precipitation in the liquid state over a certain period of time, for example, year, season, month, etc. The annual precipitation includes: rain, snow, rain and snow mixed, as well as hail, dew and fog; before the measurement, precipitation is reduced to the liquid state and then measured, so, the precipitation indicator is essentially the number of liters of water per square meter.

To estimate the amount of precipitation, whether it is large or small, whether it means a drought or a flood, it is required to compare this indicator with the average value by year, month or region. Table 1 below shows the averaged precipitation values characteristic of different regions or latitudes of the Earth:

Table 1. Precipitation by region of the Earth.

Amount of precipitation, mm or l/m2 Region of the Earth
from 1000 up to 2000 equator
from 500 up to 1000 temperate latitudes, incl. Germany
from 300 up to 500 tropics
from 100 up to 200 polar latitudes
below 100 deserts
