Abstract
The analysis of measurements of stratospheric wind and radio wave absorption in lower ionosphere in Central Europe and southern Spain shows that the apparent difference between the response of the lower ionosphere in Central (decrease of absorption) and Southern (increase of absorption) Europe to well-developed stratospheric warmings is essentially caused by the different response of the neutral middle atmosphere (Stratosphere) to stratwarms. The periods of dominant meridional wind (much less frequent in Central Europe) are accompanied by enhanced absorption of radio waves. A decrease of absorption (weakening or break-down of the winter anomaly) appears to be observed near or after the strong stratwarm maximum in both regions.
