In London, presented data from studies of hydrological processes on all six continents, as a result of which, scientists have come to the conclusion that the soil drying directly affects the number of storms occurring.
The findings have important implications for the future development of global climate models, which can simulate a large number of drought.
In the research team included scientists from Britain, the Netherlands, Austria and France, and led them to Dr. Chris Taylor from the Centre for Ecology and Hydrology in the UK.
Scientists investigated images from weather satellites that monitor the development of storm clouds around the world. In the process, they compared the occurrence of storms and moisture of land, the results at first a bit surprising.
Ie for example, in Africa, scientists knew that the storm is brewing, where it did not rain for several days. But this situation is observed in other regions of the world. And it's a given that, for example, in the U.S. or continental Europe, the climatic conditions are less extreme, in addition there is a greater vegetation cover.
The data were compared with the climate models used to simulate climate change. Our models were not true, because according to their data over the dry soils rain chance decreases, but in fact the opposite. And according to researchers, the correction model is now a priority for the responsible scientists.
Dr. Taylor added that the most important ingredients for a rain cloud elements that are heat and moisture.
On sunny days, the air is heated and formed thermals (rising air masses), which rise in the atmosphere for several kilometers. If the soil is dry, the thermals are stronger, and as is evident from the study, it causes rains often.
