Rainfall is measured by an instrument called the rain gauge. It is basically a measuring cylinder with a funnel on top to collect rainwater. The day to-day condition of the atmosphere at a place with respect to the temperature, humidity, rainfall, wind speed, etc., is called the weather at that place. temperature, humidity, and other factors are called the elements of the weather. The average weather pattern taken over a longtime, say 25 years, is called the climate of the place. The western region of India, for example Rajasthan, will show that the temperature is high during most part of the year. But during winter, which lasts only for a few months, the temperature is quite low. This region receives very little rainfall. This is the typical desert climate. It is hot and dry. The northeastern India receives rain for a major part of the year.
