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.Know More
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 about Rain
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 >
Rain water absorbs carbon dioxide from the air it passes through on its way down. The carbon dioxide reacts with the water to form carbonic acid. This mechanism is one of the principal ways in which atmospheric carbon is scrubbed from the air and put back into circulation among living systems.Full Answer >
Any time the droplets in clouds grow and come together to form drops that are large enough to create a speed of falling that is greater than the speed at which the cloud is blowing upward, then they head downward, and if they make it down without evaporating, people on the ground experience them as rain or snow. Sometimes rain evaporates again and heads back up into the clouds. The greater the amount of water vapor under the cloud and the stronger the winds on the updraft, the more likely precipitation becomes.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 >
