ENSO Prediction of CMFC Pacific SSTAprediction by analogue method for summer(JJA) (1977, 1994) 6-month prediction of Niño 3.4 index by statistical methods Niño 3.4 index: near or above normal But significance : relatively low
Dynamic Prediction by CAM3.0 ∘ Meridional circulation : strengthened in middle latitude of East Asia ∘ Okhotsk high : stronger ∘ West Pacific Subtropical High : weaker than normal Interpreting the model ∘ Temperature: near normal ∘ Precipitation: below or near normal JJA 500 hPa mean and anomaly
Physical and Statistical Prediction 500hPa Height Prediction & Anomaly by Seasonal Variation in Atmospheric Circulation Temperature: near Normal Precipitation: below or near normal Composition years : 1973, 1980, 1992, 2005, 2011
Monsoon Activity normal Nearor above normal T : near normal R : below normal Abnormal Precipitation and Temperature Predicted by MPI and Niño 3.4 Index for Summer
Summary 1. Seasonal climate outlook for summer 2013 over DPRK • Temperature : Near normal • Precipitation : Below or near normal • Cooling summer over the eastern coast area will be appeared • 2. Monsoon activity: Near normal • 3. Okhotsk high will be stronger and West Pacfic Subtropical High weaker than normal
