GEOMAGNETIC-ACTIVITY AS A POSSIBLE CAUSE OF CHANGES IN THE MIDDLE ATMOSPHERE AND TROPOSPHERE - OBSERVATIONS MADE IN PRAGUE IN THE YEARS 1932-1987

A possible relation between the 10-day, 1-month, and 2-month geomagnetic as well as solar activity, characterized by SIGMAKp and Wolf's number R, and temperatures measured at the Prague-Klementinum meteorological station in January-February of the years 1932-1987 was sought. It was found that: 1) SIGMAKp correlates with the temperature in Prague better than Wolf's number R. 2) If the QBO phase is taken into account, the correlations improve. 3) Even if the correlations improves with increasing length of the subintervals into which the individual winter periods (January-February) were derived, their statistical significance declines.
