E.5. The Temperature Of Ocean Waters
Factors AffectingÂ
- Latitude
- Unequal distribution of land and water
- Prevailing wind
- Ocean currents
- The salinity of oceanic water
Horizontal and vertical Distribution of Temperature –
- Temperature decreases with the increased depth.
- The boundary region( 100-400 m), from where there is a rapid decrease in temperature, is called the thermocline.
- Below the thermocline, the Temperature changes very slightly.
- The average temperature of surface water is about 270
- It gradually decreases from the equator towards the poles.
- The oceans in the northern hemisphere record relatively higher temperatures than in the southern hemisphere.
