The difference lies in what causes the rainfall to occur. In convectional rainfall, the sun heats the earth and the heat causes moisture from soil, plants and open water bodies to evaporate. This moisture is carried upwards through convective air currents until it reaches a certain altitude. At that point, where the air is cooler, it condenses and creates water droplets (rain). This usually occurs in the afternoon on warm summer days. Frontal rainfall occurs because of the movement of the fronts of two air masses. When a cold front is moving over a mass of warm air, it causes the warm moist air to rise. In this case, rain occurs ahead of the cold front. When a warm front is moving over a mass of cold air, the warm moist air is forced upward, and the rain occurs over or behind the front. Finally, relief rainfall is caused by changes in topography. Moist warm air can be forced upward by mountains, for example, which causes the moisture to condense into rain. This type of rainfall occurs on the side of the mountain away from the wind direction.
