where do cumulus clouds form in the atmosphere
Cumulus cloud
The height at which the cloud forms depends on the amount of moisture in the thermal that forms the cloud . Humid air will generally result in a lower cloud base . In temperate areas , the base of the cumulus clouds is usually below 550 metres ( 1,800 ft ) above ground level , but it can range up to 2,400 metres ( 7,900 ft ) in altitude . In arid and mountainous areas , the cloud base can be in excess of 6,100 metres ( 20,000 ft ) . Some
