This process often causes clouds to develop. As the clouds become heavy, the weight of the clouds can cause precipitation, or convection rainfall. Convectional storms occur in many different geographic locations, but are more severe in tropical areas where water sources are abundant and climates are warmer. They are also more severe in warmer mountain regions.
