Relief rain occurs when warm, moist air ascends along the slope of a mountain. The air then condenses and rainfall occurs on the windward side. The leeward side of the mountain receives very little rainfall. This is called the rain shadow region.
Relief rain is also termed orographic rain. It's generally seen in coastal regions where a chain of mountains runs parallel to the coast. The oncoming sea breeze bares moisture from the sea and carries the moisture towards the hills.
Many parts of the West Indies and the United Kingdom receive relief rain. The western coast of India, along the Western Ghats, also receives orographic rain.Learn More
Rain and other forms of precipitation occur when water accumulates in the clouds and falls to the ground. This occurs due to the water cycle, which continually recycles the water on Earth.Full Answer >
Orographic rainfall is rain that is produced from the lifting of moist air over a mountain. The moist air rises and cools, producing orographic clouds, which are the source of the rain. Most orographic rain falls upwind of the mountain range, with some also falling a short distance downwind. This process can produce any type of precipitation, including snow, sleet, hail or freezing drizzle.Full Answer >
Rain brings a multitude of benefits to the earth, including watering wild plants and crops, humidifying the air, creating streams and rivers, replenishing the water table and creating healthy negative ions. Perhaps the most important benefit of rain is its redistribution of fresh water in the water cycle.Full Answer >
Rain is made when water vapor in the air condenses, and the water droplets become too heavy and fall rain drops. When a mass of air cools to saturation point, it leads to condensation of the water vapor, which forms clusters of water droplets and frozen water crystals.Full Answer >
