Although the equatorial regions have the highest annual average temperatures, the salinity in the oceans is highest near the tropics because: 1. equatorial areas receive heavy rainfall 2. salinity is not affected by temperature 3. equatorial oceans experience a lot of turbulenees 4. high relative humidity in equatorial areas checks evaporation
