Cloud Streets of Warm Air Advection - Building bands of cumulus clouds indicate warm air advection as they progress to the northwest over the Houston-Galveston Bay area. Warm, moist air from the Gulf of Mexico is borne on southeasterly winds over the sun-warmed land areas. The heated air at the surface combines with the steady flow to produce parallel corridors of rising air, marked by cumulus, and subsiding air as clear. Note the lack of significant clouds over the cooler water surfaces and how the cumulus increase in size and height as they continue to acquire heat from the land surfaces.
