Warm Advection
warm air moves into a cooler region

Warm advection is the process in which the wind blows from a region of warm air to a region of cooler air. The following animation depicts a very simple example of warm advection. The horizontal lines are isotherms in degrees Fahrenheit and the arrows represent wind vectors. Winds are blowing from a region of warm air to a region of colder air, which results in a warming of the colder region. As the warm advection persists, temperatures in the colder region will begin to increase as the warmer air moves into the region of colder air.
