Explain orographic precipitation
WebJan 31, 2024 · Orographic rainfall occurs in most parts of the world. Convectional rainfall is regional in nature. There is a certainty in the convectional rainfall occurring in the equatorial areas. Comparatively, the orographic and cyclonic rainfall is less certain. And therefore, such areas are prone to very heavy rainfall, floods or droughts frequently. WebJan 3, 2024 · This is a fancy name with a very simple meaning. When wind hits a mountain and is forced to rise over the mountain, this is called orographic lift. This simple concept is such a powerful lifting force in the atmosphere that it is likely responsible for the majority of the snow that falls in big mountains. When air runs into a mountain, the side ...

WebMar 28, 2024 · Orographic precipitation, also referred to as relief precipitation, is precipitation produced upon encountering a physiographic upland by a forced upward movement of air (see anabatic wind). Two mechanisms may cause this lifting: the upward deflection of large-scale horizontal flow by the orography. Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation. Orographic lifting can have a number of effects, including precipitation, rain sh…
