Temperature close to the ground

This map displays the forecast temperature close to the ground at a given time. Note that this may be different from the air temperature. If a warm airmass moves into a region that has just experienced extreme cold, the temperature close to the ground will be colder than the air temperature, due to the fact that it takes longer for the ground to warm up than it does for the air. The opposite can also be true, where cold air moving into an area that has just seen warm weather will result in cold air temperatures and warmer temps close to the ground. This can be important for snow removal (if it’s snowing, but the ground is 40F, the snow won’t accumulate unless it falls heavily) and also for ice accretion (if it’s raining and 35F in the air, but the ground is still frozen from recent cold, ice can accumulate on roadways despite above freezing air temperatures), among other applications.

Temperatur bodennah

Der Parameter "Temperatur bodennah" zeigt die berechnete Temperatur direkt in 0 cm Höhe. Sie ist zum Beispiel sehr nützlich für winterdienstrelevante Sachen, wie zum Beispiel gefrierender Regen oder gefrierende Nässe in der Nacht. Sie ist stark von der Landnutzung (Wald, Wiesen, Stadt, ...) abhängig.
