How does the ocean affect climate?

We think of the sun as the main factor in our daily weather. If it's a sunny day, it'll probably be hot and if it's cloudy we're in for a chilly day. The ocean, however, also plays a major role in the Earth's climate and weather. It does this by pulling the sun's energy along certain paths. For example, the climate on the West Coast of America (where California is) is usually pretty mild, since the winds are warmed up by the Pacific Ocean.

The ocean is able to absorb and store heat that it gets from the sun. The water from the ocean can also affect the temperature of the atmosphere and its circulation all over the world. As a matter of fact, the upper 10 feet (3 meters) of the ocean hold the same amount of heat as is in the entire atmosphere. Water from the ocean is also the source of most of the water in the rain cycle.
