Some of us have always adored the sound of fallen raindrops hitting the roof and the smell of the rain – I think it is so peaceful. However, not every one of us like the rain, especially the individuals who live in regions with frequent rainfall. But it is evident that we require the rain because plays vital role for the cycle of returning water back to our planet. Rain is recycled water which evaporated from the oceans, lakes, rivers, and seas. Once evaporated the water will eventually fall as precipitation, and the droplet of water may travel several miles throughout this process. For every minute, each day – 1 billion tons of rain falls on earth.
The primary cause of rain production is the moisture moving along 3-dimensional zones of temperature and moisture differences known as weather fronts. If sufficient moisture and upward motion exist, precipitation falls from the convective clouds (those with sturdy upward vertical motion) like cumulonimbus (thunder clouds) that can organize into narrow rain-bands. In mountainous regions, heavy precipitation is very possible where upslope flow is maximized within the windward sides of the terrain at an elevation that forces moist air to condense and finally fall out as rainfall at the sides of mountains. On the leeward side of the mountains, desert climates can occur due to the dry air caused by a downslope flow that causes heating and the drying of the air mass. The movement of the monsoon trough, or inter-tropical convergence zone, carries rainy seasons to Savannah climes.
Water droplet which becomes sufficiently substantial to drop under gravity, due to the decrease of water vapors in the atmosphere is called Rain. It is a significant part of the water cycle and is responsible for saving the high amount of the fresh water on the Earth. Did you know that rain occurs on other planets? Or that the Antarctica is the driest continent on Earth? Understand how rain occurs and why is it essential to life on Earth. Check this 9 most interesting facts about rain.
Interesting Facts Of Rain:
1. Rain can fall to a level of 22 miles per hour.
2. One droplet of rains remains in the atmosphere of Earth for almost 10 Days.
3. Rain does not have a teardrop shape; it is ovular.
4. Every second, almost 16 million tons of water evaporates from the Earth surface.
5. Also, every second, 16 million tons of water precipitates back onto the surface of Earth (Water cycle).
6. The rain that falls from clouds in the atmosphere in the form of water droplets is referred to as precipitation.
7. Water can also fall from the sky I form of sleet, hail or snow.
8. Weather radar is usually used to detect and monitor rain.
9. Rain also occur on other planets in our solar system. Though it is very different from the rain, we experience on Earth. For instance, Rain on the Planet, Venus is made of sulfuric acid and due to steady heat, it always evaporates before it reaches the surface!
