Extended Forecasts

S2S 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 International Research Institute (IRI) data (https://iridl.ldeo.columbia.edu/SOURCES/.ECMWF/.S2S) library interface was used to develop the extended forecast. The extended forecast is based on ECMWF, NCEP and UKMO models.
 

Single Model based Extended Forecast:

The NCEP Climate Forecast version 2 (CFSv2) is a fully coupled model representing the interaction between the Earth's atmosphere, oceans, land and sea ice (Saha et. Al., 2014). The weekly forecast displayed here is the ensemble mean of 16 forecast members from the initial date.





Experimental Seasonal Forecast

The seasonal outputs are based upon the multimodal ensemble of climate forecast models includes, Climate Forecast System Version-2 (CFSV2) model, The National Aeronautics and Space Administration (NASA) seasonal forecast model, National Center for Atmospheric Research (NCAR) climate model, CANCM1 (CMC1) climate model and Geophysical Fluid Dynamics Laboratory (GFDL) climate model respectively. These models are selected on the basis of their skill score for the region Pakistan. The horizontal resolution for all the selected models is shifted to 1° X 1°.
