Explanation:

Majority of sun radiation is absorbed by the ocean, where the ocean acts like a massive, heat-retaining solar panel in which the heat would later quickly radiate into space after sunset.

The ocean doesn't just store solar radiation, it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds.
