HOW OCEANS AFFECT WEATHER


Convection is the heat going into the air or water of the atmosphere. The heat of the Earth creates circulation cells. They control mostly two-thirds of the warmness of the tropical regions and the polar regions. When air around the equator becomes hot and the air either cools down or heats up. Water vapour starts to form and turns into rain in the equator zone. The rain causes the Earths air to dry up while traveling through the north and south poles causing it to cool down. The temperature starts decreasing immediately to 30 degrees. Then two circulation cells are formed. The Ferrell cells and the Polar cells.
