A possible relation between geomagnetic activity and winter air surface temperatures in Prague

A possible relation between the 10-day geomagnetic activity, solar activity and temperatures as measured at the meteorological station Prague - Klementinum in 1932–1975 was sought. It was found that: 1) ΣKp correlates with the surface temperature in Prague substantially better than Wolf's number R. 2) The correlation between ΣKp and the surface air temperature is not very close, but is significant at the level p=0.9! 3) If the QBO phase is taken into account, the correlations for the January and February decades of the years 1956–1975 improve as in [27] (van Loon, Labitzke).
