Boundary layer skew
http://www.theweatherprediction.com/thermo/qanda/ WebIn meteorology, the planetary boundary layer(PBL), also known as the atmospheric boundary layer(ABL) or peplosphere, is the lowest part of the atmosphereand its behaviour is directly influenced by its contact with a planetary surface.[1] On Earth it usually responds to changes in surface radiative forcingin an hour or less.
