Why is humidity important for the development or deepening of low pressure over a warm sea surface?
Answer and explanation
Correct answer: Moist rising air releases latent heat during condensation and changes air density
A warm sea supplies both heat and water vapour to the lower atmosphere. Moist air can rise through convection; as it cools, water vapour condenses and releases latent heat. This release helps maintain buoyancy and supports further ascent, lowering the mass of air over the surface and encouraging pressure to fall. The exact development of a low also depends on circulation, convergence, and wind shear.
