The three-dimensional topography used in this study is composed of two, two-dimensional …
Nettet25. apr. 2012 · mountain–valley wind systems. The diurnal cycle of local winds in a mountain valley during clear or mostly clear periods of weak synoptic flow. The traditional components of the cycle are upslope ( anabatic) winds, the daytime upvalley wind, … NettetIn coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail. Winds are commonly classified by their spatial scale, their speed and direction, the forces that cause them, the regions in which they occur, and their effect. Winds have various aspects ...
Nettetof three major wind circulations: plain–mountain winds, valley winds, and slope winds. The different phasing and superposition of the valley and slope wind systems produces clockwise and counterclock-wise diurnal rotations on the right and left banks (or sidewalls) of a valley, respectively, when facing down valley (Hawkes 1947; Whiteman 1990). Nettet25. apr. 2012 · upvalley wind.
