| Abstract: | According to the date of the temperature, the precipitation, the frost, the accumulated temperature and the gale material from the record of 38 years in Jiagedaqi , the climate of the Jiagedaqi area is analyzed . The resuits show that the mean temperature appears to be going up and the precipitation appears to be descending, especially in the later 1990＇s, the warming trend increases obviously, the accumulated temperature increases obviously, especially the winter warming scope increases obviously, frost season change with global warming tendency basic consistent, but the end of the 1990＇s , 0℃ termination frost season has towed the tendency, the gale date number has the obvious reduced tendency, the violent weather event increases obviously. |
