Using the ERA5 and JRA-55 reanalysis datasets on latitude bands of nearlyequal area, we analyze the trend of 200 mbar zonal wind anomalies for theperiod 1958-2021 as well as annual-mean latitude of the polar jet stream. Wefind basically no change of 200 mbar zonal wind in either the JRA-55 or ERA5dataset. In addition, the polar jet core moves poleward in the NorthernHemisphere, but the movement is not statistically significant, while nopoleward shift at all has occurred in the Southern Hemisphere.
