Subject: how to find probable rain wall from past data (PMP) Posted: 5/21/2015 Viewed: 14768 times
i have a 50 years rainfall data, i would like know a proper method to find the maximum probable rainfal. Past data verying randomly, there is no uniform variation in a perticular month in each year.

Well I always tend to opt for the simpler approach: did you try to calculate the empiric cumulative distribution of your 50 years data?
This will only calculate the percentage of occurence of the maximum observed rainfall in your 50 year data, it won't extrapolate to a more extreme probability (such as 1 in 100 years, 1 in 1000 years), for this you'd have to use a statistical model.
