Mechanisms of producing precipitation include convective, stratiform, [6] and orographic rainfall. [7] Convective processes involve strong vertical motions that can cause the overturning of the atmosphere in that location within an hour and cause heavy precipitation, [8] while stratiform processes involve weaker upward motions and less intense precipitation over a longer duration. [9]
They include more frequent and intense heavy precipitation which affects the frequency, size and timing of floods. [46] Also droughts can alter the total amount of freshwater and cause a decline in groundwater storage, and reduction in groundwater recharge. [47] Reduction in water quality due to extreme events can also occur.
