However, katabatic winds might also reach gale force as an outblowing wind over ice-covered surfaces in Antarctica and Greenland, where the wind may be extremely strong and gusty near the coasts and less severe in mountain regions. An anabatic windfrom the Greek anabatosverbal of anabainein meaning moving upward, is a warm wind which blows up a steep slope or anabafic side, driven by heating of the slope through insolation.
