Areas of high elevation, such as mountain ranges, often drain the air of its moisture. As the air rises up the mountain, it cools. As the air cools, it loses its ability to hold water. The water then condenses out of the air and falls as precipitation.Know More
The high altitudes of mountains often receive a significant amount of precipitation. Often, this precipitation falls in the form of snow, which is why many high mountain peaks are always covered in snow. In mountains near the equator, the constantly high levels of humidity form what is called a "cloud forest." Cloud forests are habitats that feature numerous mosses, algae and epiphytic plants; often, these plants are covered in water for most of the day.
While the top of the mountain may receive abundant rainfall, mountains often remain dry on the down-wind side. This is called the "rain shadow effect," and it causes the downwind side of the mountain to remain dry for most of the year. One of the best examples of this phenomenon is created by the Himalayan Mountains. As the warm, moist air blows from the Indian Ocean, it flies up the side of the Himalayas. Most of the rain falls on the south side of the mountains, and the area on the north side of the mountains remains dry.Learn more about Rain
In the arctic tundra, the average annual precipitation ranges from 6 to 10 inches. Typically, this precipitation is in the form of snow. The arctic tundra is a cold biome that has two seasons, summer and winter.Full Answer >
In the temperate woodland and shrubland biome, the annual amounts of precipitation ranges from 100 to 1,000 millimeters (8 to 39 inches). Most of this precipitation falls during the spring and winter months. The weather in this biome varies from very hot summer months to cool or mild winters.Full Answer >
Average precipitation levels in polar climates are very low. Rainfall is normally below 10 inches per year in polar tundra climates and can be as low as 4 inches near the polar ice caps.Full Answer >
Acid rain affects the economy as the U.S. Acid Rain Regulations incurs costs per ton of sulfur, as well as by increasing the cost of electricity. While initial forecasts suggested that these costs would rise to $5 billion per year in the early phases of the program, they were around $836 million per year.Full Answer >
