The orographic effect is a meteorological phenomenon where moist air is forced to ascend over a mountain range, cooling and condensing to produce precipitation on the windward side, while creating drier conditions on the leeward side, known as a rain shadow. This effect significantly influences local climate patterns, vegetation, and water resources in mountainous regions.

Precipitation is a meteorological phenomenon where water in various forms, such as rain, snow, sleet, or hail, falls from the atmosphere to the Earth's surface. It plays a crucial role in the Earth's water cycle, influencing weather patterns and climate systems globally.

precipitation

The windward side of a mountain or island is the side that faces the prevailing winds, receiving more precipitation due to the orographic effect. This results in lush vegetation and a wetter climate compared to the leeward side, which is sheltered from the wind and typically drier.

windward side

The leeward side of a geographical feature, like a mountain, is the side sheltered from the prevailing wind, often resulting in drier conditions due to the rain shadow effect. This phenomenon significantly influences local climate, vegetation, and human settlement patterns in the region.

leeward side

A rain shadow is a dry region on the leeward side of a mountain range, where the mountains block the passage of rain-producing weather systems, casting a 'shadow' of dryness behind them. This phenomenon leads to significant differences in climate and vegetation between the windward and leeward sides of the mountain.
