The air temperature can be found by using the linear equation T = T' + ΔT, where T is the water temperature and ΔT is the temperature difference, both in degrees Celsius.
Herein we know the information of the water temperature in Antartica and the difference between water and air temperatures. Hence, we can find the air temperature by using the following linear equation:
T - T' = ΔT (1)
Where:
If we know that T' = - 2 °C and ΔT = - 9 °C, then the expression that can be used to find the air temperature is:
T = T' + ΔT
