A survey over the PMP-1 winters 1978/79–1981/82 in comparison with earlier winters

The main features of the “PMP-1 Winters” are summarized and compared with information available on earlier winters, dating back partly till the winter 1951/52. The emphasis is put on a comparison of the stratospheric temperatures over the polar region and of the development of the planetary-scale waves 1 and 2. A possible modulation of these waves by the QBO (Quasi-Biennial Oscillation) and by the sunspot cycle is discussed briefly.
