Experimental Weather Regime Forecast
This compilation of images gives the weather regime forecast for the 30 days. (A) shows the historical weather regimes as composites of 500 mb geopotential height anomalies based on over 70 years of observational analysis using NCEP Global Reanalysis data. (B) shows the impacts of each weather regime based on observational analysis for (select tabs) precipitation, atmospheric river landfalls, temperature anomalies, and Santa Ana winds probability based on historical analysis linking each weather pattern to daily weather impacts. (C) gives the weather regime probability forecast using information from ECMWF(top) and NCEP (bottom).
