The diagram depicts the formation of rain-shadow deserts as moist air interacts with mountain range
Overall, The process consists of seven stages, beginning with the moist air moving inland from sea and including with the formation of a desert on the Leeward side of a mountain. The notable feature is that rain falls on the windward side of one, while dry air descends leeward side, making much drier conditions
At the beginning of the process, winds travel from the sea towards the coast. As these winds reach the mountain range, they are pushed upwards along its slopes. When the moist air rises, it’s cooler, causing clouds to form. Eventually , the rain falls on the windward side, which result in the majority of moist air being depleted during this stage
In the finals , the dry air continues to flow over the mountain; it has lost most of its moisture. It becomes increasingly drier as it goes down on the leeward side. The dry air then travels further inland as dry winds . Because very little water reaches these areas, insufficient moisture is created . Consequently, it gradually becomes a rain-shadow desert in the inland of the mountain
