Question

What is the variation of annual precipitation in india

Answer 1

First of all, “The mean of the annual rainfalls over a period of 35 years is known as Average annual Rainfall.”

So, nobody has answered this question correctly till now.

Average annual rainfall is calculated by simply taking average of total rainfall of several consecutive years. So, considering greater no. of years will result in more correct mean value. Percentage error in mean rainfall for a period of 35 years is 1.8.

Hence, as per Indian Meteorological Department, the average annual rainfall over the whole of India is estimated as 119 cm.

Hope so it will help you ^=^
