Surface Heating and Cooling
•Surface heating by solar
energy causes ascending
motion, which tends to
decrease a surface low-pressure
center.
•In contrary, surface cooling
produces a surface high-pressure center.
•Surface heating and cooling
are the third mechanisms to
affect the developments of
low- and high-pressure systems.
• The other two processes are the (1) upper-level convergence/divergence causes
by curvature effect and jetstreak effect and (2) surface friction.
