The Occurrence Of Dry Periods And Wet Periods In The Northeastern United States
This goal of this research was to understand the occurrence of dry periods and wet periods in the northeastern United States over a 48 year period, from 1961 to 2008. An index that took into account daily precipitation and evaporation was developed and extreme value theory, a branch of statistics us...
