A similar analysis was carried out for wind components in the free atmosphere calculated from aerological soundings. An abrupt increase in the upper-air zonal wind component around 1987 was detected in January and February over North-East Europe that may form a significant part of the intensification of the western flow. This increase is accompanied by a shift in the meteorological regime near the surface over a wider area. In March, the regime shift in the upper air flow that has taken place in the middle of the 1990s is not reflected in the meteorological parameters at the surface. Besides the regime shift at the end of the 1980s, also shifts in the middle of the 1970s and at the beginning of the 2000s are suggested.
