Practice questions
Why is humidity measurement especially important in the study of monsoon regions?If actual vapour pressure is (12) and saturation vapour pressure is (24), what will be the relative humidity?Which combination is scientifically most suitable for increasing the rate of evaporation?If actual water vapour increases while temperature remains constant, why does relative humidity rise?A very small difference between dew point and air temperature indicates which condition?Why can cloud droplet formation be difficult in saturated air without condensation nuclei?Why can relative humidity be high in cold air even with a small amount of water vapour?Why does relative humidity fall during daytime warming if vapour amount remains same?What is the main energy source involved in evaporative cooling?What is the meteorological importance of latent heat release during condensation?If saturated air is cooled further, what will happen to excess water vapour?Why may evaporation not appear very rapid in coastal areas despite abundant water?Why may clouds be fewer in a desert despite rapid evaporation?If moist air rises along a mountain slope, what is the main physical reason for its temperature decrease?Why does a clear night sky increase the chance of dew formation?Which additional thermal condition is needed for frost compared with dew?If (e) remains constant in (RH=\frac{e}{e_s}\times100) and temperature rises, why can (RH) decrease?Why can evaporation slow down near a water surface in still air?How does strong wind help increase evaporation?Why are cloud droplet formation and rainfall considered different processes?
