In fact, any body with temperatures gives off heat energy in the form of radiation. This includes the moon, the earth, and even your body. But there are other forms of heat transfer that can be very important in determining our weather. Convection of heat is used by weather forecasters quite a bit in predicting temperatures.
Convection is a form of heat transfer due to the mass movement of the atmosphere.
Similar to ocean currents, atmospheric currents in the form of wind transfer heat from southern areas toward the north and cold from the north toward the south. Convective currents also transfer heat from the ground up into the atmosphere. These currents, known as thermals, can be seen when cumulus clouds develop on a warm day. The other form of heat transfer, known as conduction, is far less important in our atmosphere. Conduction is caused by molecular motion in a solid.
