evaporation

Scientists have provided strong evidence that the dynamic behind this is an increase of greenhouse gasses from human industry that trap heat, cooking the oceans to extreme levels that cause greater evaporation.

The threshold for extreme drought is reached after six months of very low rainfall or very high levels of evaporation from plants and soil - or both.

Hot weather increases the evaporation of water from soil which makes periods when there is no rain even drier.

Only its president and treasurer knew that the cordage trust was hobbled by overproduction, a lack of credit and the evaporation of its working capital.

Secondly, hotter temperatures increase the evaporation from plants and soils, so they lose more water.
