1. Rain shadow effect is a phenomenon associated with topographic precipitation, which is used to explain the significant difference of topographic uplift precipitation on windward slope and leeward slope. Specifically, when terrain uplift precipitation occurs on the windward slope of the mountain, the leeward slope can show sunny weather, forming a "rain shadow"?
2. The synoptic interpretation of the rain shadow effect is the dry adiabatic warming on the leeward slope due to the decrease of water vapor saturation after the wet gas block produces precipitation on the windward slope, and the blocking effect of the mountain itself on the topographic precipitation cloud system. Because the rain shadow effect is related to specific terrain and wind direction, it will appear repeatedly in some areas, which is of reference value for weather forecast?
3. On the climate scale, the rain shadow effect can partly explain the dry climate of the leeward slope of the mountain, which is in contrast to the windward slope. Examples include the inland desert to the west of the Great Divide in Australia and the Atacama Desert in northern Chile.
