WebMar 27, 2014 · Relative humidity (RH) is 100% times the ratio of the environmental vapour pressure, e (T), to the saturation vapour pressure es (T). RH = 100% * e (T)/es (T) The environmental vapour pressure is the saturation vapour pressure at the dew point or e (T) = es (Td) so RH becomes RH = 100% * es (Td)/es (T) In other words: if you have a parcel of ...

WebSPECIFIC AND RELATIVE HUMIDITY. Specific humidity, w, (or absolute humidity) gives the measure of the water vapor in the air: w = m v / m a (kg of H 2 O vapor/kg dry air). using the ideal gas law: w = 0.622 ( P v / P a ) or: w = 0.622 [ P v / ( P - P v )] Air can hold only a certain amount of water vapor. The limit is reached when P v reaches the saturation pressure of … WebThe Peak of both parameters occurred on the same day (day 12) and the least was seen on day 25 and day 30.
