The evaporation creates a negative water vapor pressure develops in the surrounding cells of the leaf. (scientificamerican.com)
Therefore, the August - Roche - Magnus equation implies that saturation water vapor pressure changes approximately exponentially with temperature under typical atmospheric conditions, and hence the water - holding capacity of the atmosphere increases by about 7 % for every 1 °C rise in temperature.

The solution of the relation yields an exponential dependence of saturated water vapor pressure on temperature, which can be mis - interpreted in accurately estimating the frequency / intensity of extreme events like cyclones or high - intensity rainfalls during the non-rainy season.
