4. what is the mean amount of rainfall?

The middle value of aggregate sum of precipitation recorded during a schedule month or year is called as mean amount of rainfall. Both mean and middle precipitation are incorporated into these insights, despite the fact that from the meteorological perspective, the middle is generally the favored proportion of 'normal' or 'ordinary' precipitation.
