Foehn wind means "hairdryer," and the form "phon" is used in French-speaking parts of Switzerland as well as in Italy. The form "fen" is used in Croatia and Slovenia. Regionally, these winds are known by many different names. These include: Foehn wind A föhn or foehn (, ) is a type of dry, warm, down-slope wind that occurs in the lee (downwind side) of a mountain range. It is a rain shadow wind that results from the subsequent adiabatic warming of air that has dropped most of its moisture on windward slopes ("see" orographic lift). As a consequence of the different adiabatic
Weather radar angles are used. Due to the Earth's curvature and change of index of refraction with height, the radar cannot "see" below the height above ground of the minimal angle (shown in green) or closer to the radar than the maximal one (shown as a red cone in the center). Because the targets are not unique in each volume, the radar equation has to be developed beyond the basic one. Assuming a monostatic radar where formula_5: Weather radar Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its
