A weather front or front is a
narrow region between two air masses of different densities. Because of the
difference in density between warm and cold front, cold air tends to go
underneath the warmer air. It often creates the strongest winds above the
ground surface. This is caused due to the heat and mass transfer between
particles of air. They can be slowed down by the presence of mountains and
valleys. Cold air moves fast and the temperature around it can be felt as if
you are blown away due to its density. Whereas warm air moves slowly.
