FIGURE 16.25 Weather stations collect data on land and sea. Weather balloons, satellites, and radar collect data in the atmosphere. Many weather satellites orbit Earth. They constantly collect and transmit weather data from high above the surface. A radar device sends out radio waves in all directions. The waves bounce off water in the atmosphere and then return to the sender. The radar data shows where precipitation is falling. Its raining in the orange-shaded area shown above.

This diagram shows the effect of rains on hills. The moist air from the green side of the hills rising up in the air and condenses as water vapor. This is called precipitation. The other side of the hill form the rain shadow region. Rain shadow region is a region having little rainfall because it is sheltered from prevailing rain-bearing winds by a range of hills. The dry air descends from this region.

climate and its causes
DD_0024
The diagram is a representation of how a rain shadow is formed. A rain shadow is a dry region of land on the side of a mountain range that is protected from the prevailing winds. Prevailing winds are the winds that occur most of the time in a particular location on the Earth. The protected side of a mountain range is also called the lee side or the down-wind side. Prevailing winds carry air toward the mountain range. As the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. On this side of the mountains, called the windward side, precipitation falls in the form of rain or snow. The windward side of a mountain range is moist and lush because of this precipitation. Once the air passes over the mountain range, it moves down the other side, warms, and dries out. This dry air produces a rain shadow. Land in a rain shadow is typically very dry and receives much less precipitation and cloud cover than land on the windward side of the mountain range.
