Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. [ 1 ] : 162 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 precipitation occurs when moist air is forced upwards over rising terrain and condenses on the slope, such as a mountain. Precipitation can fall in either liquid or solid phases, is mixed with both, or transition between them at the freezing level. Liquid forms of precipitation include rain and drizzle and dew.
Orographic precipitation is precipitation created through the lifting action of air due to air masses moving over terrain such as mountains and hills, which is most common behind cold fronts that move into mountainous areas. It may sometimes occur in advance of warm fronts moving northward to the east of mountainous terrain.
Computer models simulating these factors have shown that narrow barriers and steeper slopes produce stronger updraft speeds, which in turn increase orographic precipitation. Orographic precipitation is known to occur on oceanic islands, such as the Hawaiian Islands and New Zealand; much of the rainfall received on such islands is on the ...

In the news release, Franklin advised people to push or sweep snow rather than lifting and throwing it. That involves less exertion. And if the wind is blowing, be extra-careful. Wind makes ...
Mechanisms of producing precipitation include convective, stratiform, [10] and orographic rainfall. [11] Convective processes involve strong vertical motions that can cause the overturning of the atmosphere in that location within an hour and cause heavy precipitation, [ 12 ] while stratiform processes involve weaker upward motions and less ...
Minnie Driver knows how to get a conversation started. Amid the growing number of celebrities candidly speaking about their cosmetic enhancements, The Assessment actress, 54, asked a series of ...
