convectional rainfall
frontal rainfall

warm moist air blows in and rises over hills or mountains, cools and condenses into clouds and we get rain.
where does the warm air come from for relief rainfall?
The Atlantic
What is convectional Rainfall?
During the summer, strong heating from the sun causes the ground to heat up rapidly. This can set up rising air pockets of warm air, known as convection currents. Warm air rises rapidly to high altitudes where it cools.
what are the rising air pockets known as during convectional rainfall?`
convection currents
What is frontal Rainfall?
frontal rainfall develops along weather fronts which form where two air masses meet. Warm moist air meets cold air and forced upwards. It rises, cools and condenses to from rain.
where does frontal rainfall develop?
along two weather fronts
