Convection: is the transfer of heat through fluids (gases or liquids) from a warmer spot to a cooler spot.
Hawaiian Translation: Paialewa
Convection Air Currents (gas)
Day: The land is warmer than the ocean. The warm air over the land rises and the cooler air over the ocean sinks and rushes in underneath to fill the space. This heat transfer by a circulation of rising warm air (less dense) and sinking cooler air (denser) creates air currents with an onshore breeze.
Night: The water cools off more slowly than the land and the air above the water is slightly warmer than over the land. The warmer air over the water rises and the cool air over the land sinks which creates air currents with an off shore breeze.
