Relief rainfall, also known as orographic rainfall, is a type of rain caused by warm, moist air that is forced to rise as it passes over higher elevations. As the moist air rises, it also cools and condenses, forming clouds and eventually, rain.Continue Reading
After the air flows over the top of the mountain and has dropped down to the other side, it warms once again. Because of this, the air now has a greater ability to carry water moisture and so there is little rain on the far side of the mountain. This area, opposite of the relief rainfall, is called the rain shadow.
Relief rainfall is very common in mountainous areas, especially on the west coast of the United Kingdom, since the prevailing weather also comes from that direction.Learn more about Environmental Science
Some of the abiotic factors found in a tropical rainforest are high temperatures, heavy rainfall, poor nutrient content in soil and sunlight that is found primarily at the tree canopy level while remaining limited at ground level. Because of the heavy overhead canopy, the forest floor may receive as little as 2 percent of the sunlight. Precipitation, which is a significant abiotic factor in a non-aquatic ecosystem, can range between 98 and 177 inches annually in a tropical rainforest.Full Answer >
A climatogram is graph chart that displays only the rainfall and temperature of a given area. A climatogram is a measure of the general climate of a large ecosystem, also known as a biome.Full Answer >
The tundra and desert biomes receive the least amount of rainfall. The annual rainfall total of a tundra averages between 10 to 25 cm each year, while the desert receives fewer than 25 cm per year.Full Answer >
The desert and the nonforest biome (tundra) are the two biomes that receive the least amount of rainfall during the year. The tundra receives very little rainfall in the form of liquid water, and the desert receives less than 9.9 inches per year.Full Answer >
