Rain. It’s one of those things that we don’t really think about until it starts to pour down on us, but what is the real reason for rain? Why do we need it and where does it come from? Well, as you might know, water needs to evaporate into the air in order to form clouds and produce rain. This process is called condensation.

The earth releases heat which makes its surface dryer than normal. Clouds are formed when cold air meets warm moist air causing condensation (water vapor) which then changes back into a liquid state (rain). The water is then carried away from the earth’s surface to form oceans.

In order for this process to start, there must be an area where warmer air can meet cooler air (or humid and dry). This usually happens in a certain region of clouds called cumulus or towering vertical convective clouds with thick bases that are fair-weather type because they don’t have enough strength to produce rain.

These types of storms will eventually dissipate if it doesn’t find a way to break through warm gulf currents which release heat at the bottom of these storms causing them to evaporate too quickly before reaching cold ocean waters near Alaska. To get more technical: upper level atmosphere winds blow towards Antarctica as low pressure zones develop over the continent releasing cold
