Heat transfer horizontally within the atmosphere is called

Convection transfers heat vertically into the atmosphere. In order for heat to be transferred to other regions, it must be transferred horizontally by the wind. The horizontal transfer of heat by the wind is called advection. Advection is a transport mechanism of a substance or conserved property by a fluid due to the fluid’s bulk motion. An example of advection is the transport of pollutants or silt in a river by bulk water flow downstream.
