Extreme Value analysis of Annual mean Rianfall of Data from 28 stations of Pakistan from Period 1985 to 2016

Abstract

The climate of earth has been changing with time, over million of years and mostly in the previous two centuries with the involvement of greenhouse effect, which has put the climate on stake in an unprecedented level. Change of solar cycle patterns, atmospheric changes, impacts of El-Nino southern oscillation (ENSO), sea ice extent changes, natural biosphere variability are the reasons that show the evidence of both external and internal references to change and variability. The different earth components are also subjected to show the variation in response to all these variability. The surface air temperature has increased around 2.9°C in Boreal Asia over the last century. The nations located in Asia subjected to the greenhouse and climate change effects are expected to have more shift patterns of floods, storms, droughts and also the increase in sea level rise. The historical evidences of these region show that they are more vulnerable to the variation in monsoons, tropical cyclones and El-Nino southern oscillation
