Clouds and precipitation
Practice questions
Why is it scientifically incomplete to treat cloud and precipitation as the same process?If the atmospheric column has moisture but a dry layer in the middle what effect can occur on surface rainfall?If widespread layered clouds gradually change into vertically developed clouds how can rainfall style change?If large particles form in a cloud but strong uplift continues why may they not fall immediately?If clouds appear in a rain shadow area but rainfall remains low what conclusion is appropriate?If turbulence is high in a cloud what balanced effect on droplet size is possible?If moisture is high and uplift is continuous why is precipitation chance from cloud strong?If only high thin cirrus clouds are present why is heavy surface rainfall unlikely?If droplets fall from a cloud but both melting and evaporation are possible in lower air what will final precipitation depend on?If moist air keeps rising on a windward slope for a long time why can rainfall persist?If below-freezing zones are small in a storm cloud what will hinder large hail growth?If raindrops are large and wind is also strong why can surface impact increase?Why can it be wrong to use only colour in cloud classification?If small liquid drops are continuously falling from a cloud but they are not large raindrops which form is likely?If droplet growth is rapid and lower air is not very dry why does surface rainfall chance increase?If a cloud has enough moisture uplift and condensation nuclei yet rain is low what cause is possible?If low clouds form above a river valley while higher clouds occur nearby which local factor can help explain it?If heavy rain occurs at the surface in a short time what immediate water cycle effect can occur?If supercooled liquid droplets exist in a cloud why are they considered different from ordinary liquid droplets?If a weather system first gives widespread layered rain and later local thunder rain what change is indicated?
