Precipitation is the water released from clouds as rain, hail, snow, freezing rain or sleet. Precipitation is measured using a rain gauge. It is a simple machine that measures how much water has fallen in it. Its unit is usually millimetre (mm). (I was very confused about how that is possible when I was younger because I thought the larger diameter the gauge, the lesser mm shown right? Actually there is a simple reason behind it. Rain falls equally everywhere. So if it is a gauge with a larger diameter the more water will fall as rain is equally distributed.) Now let’s discuss about rain in India. The driest place in India is Jaisalmer in Rajasthan. Here people experience 209 mm of rain on average per year. The wettest place in India is Mawsynram in Meghalaya. It is also said to be the wettest place on earth with an average rainfall of 11,872 per year! The highest ever rainfall recorded on a day in Mawsynram is about 1,003 mm, which is lesser than the average rainfall in Delhi per year, which is 790 mm. Monsoon in India comes on around June 1st, which starts in Kerala and covers the entire country by around June 15th. I was living in Kohima in Nagaland, which receives around 2,899 mm of rainfall per year. My neighbouring capital, Aizawl in Mizoram, receives a total of 1,8049 mm per year.
