Which statement is not true about the LCL (lifting condensation level)?
A)Below the LCL the air temperature is greater than the dew-point temperature.
B)The relative humidity is 100 percent at the LCL.
C)The vapor pressure is equal to the saturation vapor pressure above the LCL.
D)Evaporation exceeds condensation above the LCL.

Question

The statement "Evaporation exceeds condensation above the LCL" is not true. Above the LCL, the air cools at the dry adiabatic lapse rate, and if it becomes saturated, then condensation will occur. The saturation vapor pressure decreases with decreasing temperature, so the vapor pressure will be less than the saturation vapor pressure above the LCL.
