Most often, Cumulus clouds occur in cold air masses in the rear of the cyclone, but are often observed in warm air masses in cyclones and anticyclones except for the Central part of the latter. In temperate and high latitudes observed mainly in the warm season second half of spring, summer and first half of autumn, and in the tropics year-round. As a rule, occur in the middle of the day and destroyed in the evening although the seas can be observed at night. The height of the lower boundary of the Cumulus clouds strongly depends on the humidity of the ground air and is often from 800 to 1500 m, and in dry air masses especially in the steppes and deserts can be 2-3 km, sometimes even 4-4.5 km.
