Orographic Rainfall: Understanding its Mechanism and Process

Orographic rainfall is a type of precipitation that is created when moist air is pushed up to a mountain range. This occurs when air masses move from low to high altitudes and the air becomes cooler and more humid, leading to the formation of clouds and eventually precipitation (Orographic Rainfall, 2020). This process is usually due to the presence of a strong wind blowing from the sea onto the mountains. As the air is forced up the mountain, the air expands and cools due to the decrease in atmospheric pressure, causing the water vapour to condense and form clouds. If the clouds become sufficiently cold, the water droplets form and fall as rain (Kendall, 2017). The windward side of the mountain range experiences a higher amount of precipitation compared to the leeward side. This process of orographic rainfall is particularly relevant in mountainous regions where it is responsible for a large part of the total precipitation. In conclusion, orographic rainfall is a type of precipitation that is caused by the windward side of a mountain range. It occurs when moist air is forced up the mountain, causing the air to expand and cool, resulting in the formation of clouds and eventually… Cont…
