The teleconnection between the global mean surface air temperature and precipitation over Europe

Abstract

The teleconnetion between the Global Mean Surface Temperature (GMST) and Prediction Center Merged Analysis of Precipitation (CMAP) data over Europe has been investigated. For the purpose of the present study a 2.5 × 2.5 degree latitude/longitude gridded monthly data for surface temperature and precipitation over Europe through the period (1979-2005) has been used. The statistical annual and seasonal correlations between the temperature and precipitation over Europe have been studied. The results revealed that significant annual and seasonal correlations existed between the surface temperature and precipitation over Europe. It is clear that the significant correlations vary from region to region over Europe. In general, the time lags or time leads of the annual and seasonal surface temperature has a distinct significant correlation rather than that without time delay between surface temperature and precipitation. These results revealed that there is a feedback mechanism between the GMST and CMAP over Europe. © The International Journal of Meteorology.
