Saturation Vapour Pressure in Losses from Precipitation Formulas

Saturation Vapour Pressure at Water Surface (mm of mercury) is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature. And is denoted by e_s. Saturation Vapour Pressure is usually measured using the Millimeter Mercury (0 °C) for Pressure. Note that the value of Saturation Vapour Pressure is always negative.
