The windward side On the windward side of mountains, much of the moisture in the air falls as rain. This frequently means that the region on the opposite side of the mountain (the leeward side) receives significantly less rain—an phenomenon known as a "rain shadow"—resulting in a desert.
However, this is not always the case. If there are other factors at work, such as another mountain blocking the wind, then the leeward side may also receive rainfall. Also, if there are glaciers on the leeward side, they can contribute to its wetness by melting and releasing water vapor into the cloudbase. Finally, if there are orographic effects going on, such as when a forest grows on a cliff face, then the leeward side could also receive more rain.
Overall, though, the windward side of mountains tends to receive more precipitation.
Windward Precipitation generally falls on the mountain's summit and windward slopes (the side where the air travels up). When the air falls on the other side, or leeward side, it has lost the majority of its moisture owing to rain. Leeward areas often experience less rainfall than windward areas due to evaporation from the ground.
Hail and snowfall occur primarily on the windward side because these particles are driven by winds upward toward the summit. As a result, wind-blown debris is usually found near the top of mountain peaks. Rockfalls and landslides are also common in windy places like Mount Washington in New Hampshire. The leeward side of the mountain may receive small hail and snowflakes carried by low-level clouds but does not produce as much large hail because strong winds tend to blow away small hailstones before they can grow large enough to fall off the mountain.
The amount of precipitation that falls on each side of the mountain depends on many factors such as elevation, latitude, and proximity to oceans or continents. At high elevations, there is less moisture in the air so less rain or snow will fall. If a continent is close by, moisture from oceans or lakes can be transported inland causing mountains to become covered in forests instead of being bare. Climate scientists use data about the distribution of precipitation around mountains to learn more about climate change over time.
Rain shadows can be cast by mountains and mountain ranges. The air cools and precipitation falls when winds increase on the windward side of a mountain range. The air is dry and sinks on the other side of the range, the leeward side. As a result, on the leeward side of a mountain range, there is relatively little precipitation. Snowfall is usually limited to the windward sides of high peaks, while the leeward sides are marked by rainforest.
Mountains can have a major impact on climate. They can cause changes in temperature and precipitation by blocking heat from reaching the earth's surface or by absorbing moisture from the clouds that form over them. This can lead to local weather conditions such as deserts on the leeward side of a mountain or frozen poles near a glacier on its windward side.
Some mountains play an important role in water cycles on Earth. For example, the Andes act as a barrier between the warm waters of the ocean and the cold currents that flow toward South America, which causes some of the largest tropical storms in history to develop in the Atlantic Ocean. These storms then have no place else to go but up against the steep slopes of the mountains, causing devastation where ever they fall out into the sea.
Other mountains serve a similar function but are too small to affect global weather patterns. Still others remain isolated peaks with no influence on their surroundings.
Warm, dry air is frequently linked with a mountain's leeward side. Rain shadows are formed on the leeward slopes of mountain ranges, resulting in deserts or other low-precipitation regions. This has an effect on both the condensation and precipitation water cycle steps.
On the ocean floor, where there is no land to rise up above it, leeward areas receive less rain than windward areas. The difference in rainfall between these two sides of islands and continents is called "island syndrome". Island syndrome can also occur on large bodies of water such as lakes or ponds. Leeward areas of these bodies of water often have less rainfall than windward areas because they are exposed to the wind which prevents clouds from forming and therefore no rain drops can fall. Wind also causes waves which wash away any soil that might otherwise hold moisture.

After passing over the mountain range, the air travels down the other side, where it heats and dries out. A rain shadow is cast by the dry air. Area under a rain shadow is often exceedingly dry and receives far less precipitation and cloud cover than land on the mountain range's windward side. Plants that grow in these conditions are called desert flora.
The area around Mount Everest is known as the Himalaya, after its highest peak. It is a large mountain range in Asia, extending from north-east India into China. The Himalaya has many peaks over 8,000 feet (2,440 m) high, making it the highest mountain range on Earth not covered in ice or snow.
Everest is also one of the most dangerous places on Earth. An avalanche can bury someone standing right next to the mountain's edge. Flooding can occur when melting snow causes rivers to overflow their banks. The danger comes from all angles: up, down, north, south, across open spaces or within buildings. There have been deaths due simply to people ignoring warnings not to climb mountains.
People have died in accidents related to falls from cliffs, rocks, and trees while trying to capture photos or videos on the mountain. In 2013, an Australian woman died while climbing Mount Everest. She was attempting to climb the tallest mountain on each continent; her goal was to raise awareness for mental health issues.
