WebApr 13, 2024 · A significant global transition to flash droughts is driven by regional increases in flash drought ratio over 74% of the IPCC SREX regions, notably for the significant increases (P < 0.1) over East and North Asia, Europe, Sahara, and the west coast of South America ().Moreover, the onset speed of subseasonal droughts has increased over most … Vapour-pressure deficit, or VPD, is the difference (deficit) between the amount of moisture in the air and how much moisture the air can hold when it is saturated. Once air becomes saturated, water will condense out to form clouds, dew or films of water over leaves. It is this last instance that makes VPD important for greenhouse regulation.
