Extended Forecast
The extended forecast is based on Sub-seasonal to Seasonal (S2S) data (Vitart et al. 2017). S2S is a joint initiative of the World Weather Research Programme (WWRP) and the World Climate Research Programme (WCRP). The original S2S database is hosted at ECMWF ( https://apps.ecmwf.int). We have used IRI (https://iridl.ldeo.columbia.edu/SOURCES/.ECMWF/.S2S ) data library interface to create the extended forecast. The ECMWF, NCEP and UKMO model datasets with grid resolution 1.5X1.5 [Lon; Lat] are used to create ensemble mean extended forecasts for the South Asian region mainly focus on Pakistan. This extended forecast is likely to update provided with the availability of S2S updated datasets in IRI data library.
