Since the end of the 1980s strong changes in air temperature have been observed in Europe. Mainly the temperatures in winter and in the early spring, which are decisive for the plant development in spring, changed distinctly. Most of the last years were warmer than the long-term averages. These observed changes in temperature correspond well to changes in the circulation pattern over Europe. The increased frequency of positive phases in the North Atlantic Oscillation (NAO) index since 1989 led to milder temperatures in winter and in the early spring, because of the prevailing westerly winds from the Atlantic Ocean during this time of the year.
