Frictional drag

From Glossary of Meteorology

frictional drag

  1. The molecular (viscous) retarding force on an object, such as air, as it moves across the earth's surface.

    In the atmospheric boundary layer, turbulent drag dominates by many orders of magnitude over molecular frictional drag.

  2. The retarding force that an object such as a raindrop or airplane encounters as it moves through the atmosphere.
