Differences in mid-latitude stratospheric winds between reanalysis data and versus radiosonde observations at Prague

Popis výsledku v původním jazyce

Reanalysis data are very useful for studying the stratosphere. In this paper, we mutually compare three of them, ERA-40, ERA-Interim and NCEP/NCAR, and compare them with balloon radiosonde observations from Prague. This comparison is done for wind speedand direction at pressure levels 100 and 10 hPa and for various periods between 1957 and 2009. The results show that the differences between reanalysis vary. Wind speed data from all three analyses reasonably agree except for the 10 hPa historical data before 1966 and particularly ERA-40 data at the end of the data series (1998?2001). The quality of the ERA-40 10 hPa stratospheric wind data has been proven to be substantially worse over the last four ERA-40 years of 1998?2001 (2002) compared to previousyears, both in wind speed and wind direction. The reanalysis data results are compared with radiosonde observations from Prague at 10 hPa for the months of February between 1989 and 2009. The results show that there are sometimes surpris
