Question

How do cyclones, sea waves, salinity,pollution and conventional currents affect the temperature of sea water?

Answer 1

Insolation: The average daily duration of insolation and its intensity.

Heat loss: The loss of energy by reflection, scattering, evaporation and radiation.

Albedo: The albedo of the sea (depending on the angle of sun rays).

The physical characteristics of the sea surface: 
Boiling point of the sea water is increased in the case of higher salinity and vice versa 
[Salinity increased == Boiling point increased == Evaporation decreased].The presence of submarine ridges and sills [Marginal Seas]:Temperature is affected due to lesser mixing of waters on the opposite sides of the ridges or sills.

The shape of the ocean: 
The latitudinally extensive seas in low latitude regions have warmer surface water than longitudinally extensive sea [Mediterranean Sea records higher temperature than the longitudinally extensive Gulf of California].

The enclosed seas (Marginal Seas – Gulf, Bay etc.) in the low latitudes record relatively higher temperature than the open seas; whereas the enclosed seas in the high latitudes have lower temperature than the open seas.

Local weather conditions such as cyclones.Unequal distribution of land and water: 
The oceans in the northern hemisphere receive more heat due to their contact with larger extent of land than the oceans in the southern hemisphere.
