Sea Ice Cycle
Evaporation
The evaporation of a water surface goes on continually under favourable conditions. It requires heat, and the heat is taken from the water itself, thus lowering its temperature. The amount of heat loss due to evaporation depends on several factors including the wind speed, relative humidity near the water surface, and the temperature difference between air and water.
Conduction
The process by which heat is transferred from the ocean to the atmosphere through the movement of particle is known as conduction. When warm air is in contact with the cold ocean water, heat is transferred from the air to the water; heat will be conducted down into the ocean. When the water is warmer, heat is transferred from the water to the air; heat will be conducted away from the ocean.
Convection
Convection also plays a part in assisting the transfer of heat away from the ocean surface because when the air near the warm ocean gets heated, it expands, rises and carries heat away from the ocean.
