Tempo Spatial Behavior of Drought in Iran
As the first step in introducing the geographical characteristics of drought events in Iran I have prepared a collection of 37 drought map time series. To construct these maps drought is defied as follow
DI = ( P - Mean ) / Sd
where DI is Drought index , P is annual precipitation ,and Sd is standard deviation.
