Convection
qConvection is heat
transfer by mass motion of a fluid (such
as air or water).
qConvection is produced
when the heated fluid moves away from the heat source and carries energy with it.
qConvection is an
efficient mechanism of heat transfer for
the atmosphere in some regions (such as
the tropics) but is an inefficient
mechanism in other regions (such as the
polar regions).
