Assume a dry atmosphere in which the potential temperature is constant. at the surface, the temperature is 10°c and the pressure is 1013 hpa. what is the potential temperature? if an air parcel were raised adiabatically to 963 hpa what would the temperature be? use the hydrostatic relation to estimate the change in altitude.
