摘要
The observed trends in some cold indices in the island of Majorca are analysed using the available series of the daily minimum temperatures of the Majorca Airport (1972-2008), supplemented with the inspection of eight more climatological stations of the island covering at least 30 simultaneous years. The analysis yields a statistically significant trend to a rise of about 0.6 degrees C per decade for the ensemble of the stations. There is also a clear shortening of the season with days with T below 0 degrees C or 7 degrees C, but the yearly minima or the dates of the first and last occurrence of these values do not show so well-defined tendencies. A rise in night-time cloud cover could be related to such behaviour. Copyright (C) 2009 Royal Meteorological Society
