Why can layered clouds be more likely in a stable atmosphere?Why is vertical cloud development greater in an unstable atmosphere?What is the importance of dew point temperature in cloud formation?Clouds giving long-duration uniform rainfall are generally of what nature?If falling precipitation drops freeze near a cold surface, which form can occur?Dew and rain both involve water drops, yet why are they different?Why can visibility below a dense cloud decrease when droplet concentration is high?Why can precipitation probability increase when cloud water content increases?Why can raindrops become slightly flattened instead of perfectly spherical?Why is local relief considered important in the study of clouds and precipitation?If moist air rises over a mountain and gives rain on the windward slope why does dryness increase on the leeward slope?In which condition can clouds exist but rainfall may not reach the ground?Why are cumulonimbus clouds especially favourable for hail formation?Why can the chance of convectional rainfall increase in the afternoon?If a cloud has very tiny droplets but they do not join together why will rainfall not occur?What is the correct difference in rainfall nature between nimbostratus and cumulonimbus clouds?Why do cirrus clouds produce little precipitation reaching the ground despite being very high?Why is the type of precipitation affected by vertical temperature?When condensation nuclei are numerous cloud droplet number may increase but why may each droplet remain small?If a cloud is dense but vertical motion is weak why may hail chance be low?
