Η επίδραση της Madden-Julian κύμανσης (MJO) στο κλίμα της Ευρώπης = The impact of Madden-Julian oscillation (MJO) on the European climate
Περίληψη
The aim of the present study is to investigate the impact of Madden-Julian Oscillation on the climate of European area, and in particular the correlation of the eight MJO phases with specific climate parameters, both for winter and summer. For this purpose, NCEP/NCAR reanalysis data were used, covering the period 1976-2015. The reanalysis represent the anomalies and mean condition for the climate parameters of temperature, rainfall, atmospheric pressure, wind at surface and at 250hPa. Extreme values of the RMM index (>90%) were chosen and they were visualized for each parameter. The results show that for each climate parameter, different conclusions are obtained per phase, which vary by season. Specifically, for the winter period the 7th and 8th phase of the MJO is associated with a decrease in temperature mainly in N-NE Europe. The increase in temperature on the Scandinavian region is associated with the 1st and 2nd phase. On the other hand, during the summer season, the decrease in temperature in central and northern Europe is associated with phases 4 to 6. The enhancement of the positive NAO phase is associated with an increase in rainfall in the Scandinavian region in phases 2 to 4 (winter), while the weakening of the Azores cyclone (3rd, 5th and 8th phase-summer) is associated with the decrease in precipitation parameter in central Europe. The 1st and 2nd phase of MJO is associated with the strengthening of the Etesian winds in eastern Mediterranean during summer season.
