The Sea surface temperature (red) is leading with some months. The land temperature (green) follows, making higer spikes.
- The oceans have two thirds of the Earth's surface, and can store more heat than land surface.
- Land surface heats quicker and cools quicker as well.
- Land surface is heated up by direct insolation from the sunlight plus redirected ocean heat, trapped by the air. The warm air is moved by the winds over the land, where it reduces cooling of the land mass.
