Heat and Weather

This video explores both convection and radiation to explain how weather is related to the transfer of heat energy. Convection occurs when temperature differences arise within a fluid, such as an ocean, and fluid motion almost certainly follows in which heat is transferred from one area to another. Movements of hot ocean currents can have profound effects on global weather. Radiation is energy traveling in the form of electromagnetic waves or photons. An example of this regarding weather would be the effect of the Sun melting an ice cap, or the greenhouse effect, whereby heat is trapped within the atmosphere.
