Analyse the factors that control the heat balance at 20°N latitude. Although at 20°North the heat balance is surplus even then why is this area not progressively heated up ?
Answer
Short Answer
The heat balance is surplus at 20°N. But this area is not progressively heated because the surplus heat energy from the tropics is redistributed polewards through latent heat released by water vapour through conduction by warm air masses and by ocean currents. Thereby tropics do not get progressively heated up.
