An avalanche.
A warm dry air mass typically brings clear skies, warm temperatures, and low humidity to the area over which it moves. It can lead to dry conditions and increased evaporation, which may contribute to heatwaves and drought.
A warm and dry air mass can make the area over which it moves arid and less humid. This is why deserts have dry air while coastal areas are humid.
landlocked and undeveloped dry and mountainous
the land which have less or scracity of water is called dry land area such as deserts are dry and xerophytic
The dry side of a mountain is called the leeward side. This is the side away from the wind. The dry area is known as a rain shadow.
A rain shadow is a dry area on the lee side of a mountainous area. The mountains block the passage of rain-producing weather systems casting a "shadow" of dryness behind them. As shown by the diagram to the right, the warm moist air is "pulled" by the prevailing winds over a mountain. Then it condenses and precipitates and the dry air moves forward leaving a rain shadow behind the mountain.

The entire Sahara is dry. That is why it is called a desert.
