Nao index forecast
http://research.jisao.washington.edu/data_sets/nao/ WitrynaThe NAM (or Arctic Oscillation) is defined as the first EOF of NH (20°-90°N) winter SLP data. It explains 23% of the extended winter mean (December-March) variance, and it is clearly dominated by the NAO structure in the Atlantic sector. Although there are some subtle differences from the NAO regional pattern over the Atlantic and Arctic (see ...

WitrynaThe NAO exhibits considerable interseasonal and interannual variability, and prolonged periods (several months) of both positive and negative phases of the pattern are common. The NAO index is obtained by projecting the NAO loading pattern to the daily anomaly 500 millibar height field over 0-90°N. Witryna5 paź 2024 · The NAO index (NAOI) is the quantitative indicator that can reflect the intensity of the NAO events, and its traditional definition is the normalized sea level pressure (SLP) difference between Azores and Iceland.
Witryna12 gru 2005 · The daily NAO indices are shown for the previous 120 days, and the ensemble forecasts of the daily NAO index at selected lead times are appended onto the time series. The indices are standardized by standard deviation of the observed monthly NAO index from 1950-2000 interpolated to the day in question. WitrynaWe provide global forecasts, climate reanalyses and specific datasets, designed to meet different user requirements. These are available via the web, point-to-point dissemination, data servers and broadcasting. ECMWF’s operational forecasts aim to show how the weather is most likely to evolve.
