Abstract: In this study, the long term change of the Arabian Peninsula subtropical jet stream (APJS) is investigated for winter time of the period 1980-2014, using data retrieved from NCEP/NCAR reanalysis of the geopotential heights 300 hPa, 200 hPa and 150 hPa. The value and position of the monthly mean of the maximum zonal wind in the jet core are determined for the mentioned period and analysed. We found that the APJS has experienced a pronounced change. It is shifting poleward and eastward for about 1.5° in January and 2.5° in February also its speed has a slight increase during autumn and more pronounced in winter. However, it is decreasing during spring and the beginning of summer. The analysis of points of different positions shows that the wind speed is broadly decreasing in the tropics, whereas the wind speed increases in the subtropics.
