For the following table, fill in the missing values. Tparcel refers to the temperature of a single parcel being lifted from 0 – 5 km, whereas Tenvironment represents the environmental lapse rate. "e" is the yapour pressure and "es" is the saturation yapour pressure. The figure relating saturation yapour pressure and temperature can be found below. The dry adiabatic lapse rate is 10° C/km and the moist adiabatic lapse rate is constant and 6° C/km.
