The spatial and temporal characteristics, abrupt change, variation periodic and possible atmospheric circulation influence factor are analyzed through using linear trend, Mann-Kendall nonparametric test, wavelet analysis and the data from 1960 to 2013 of Yunnan Province 0 cm surface temperature. The results showed that:on the whole, the distribution characteristics of annual average surface temperature, annual average minimum surface temperature were low in the northern region and high in the southern region; but the annual average maximum temperature was low in the northwest and northeast, high in the central and southern areas, high in deep valley, low in the plateau area, lower in the high mountain region. at the same time, there were differences on the regional scales, the annual average surface temperature, annual average maximum (minimum) surface temperature high value center mainly distributed in Jinsha River valley (Yuanmou meteorological station) and Yuanjiang River valley (Yuanjiang meteorological station), the Valley South Lancang River and its tributaries (Jinghong and Mengla meteorological station); the seasonal distributions of annual average surface temperature, annual average maximum (minimum) surface temperature were similar to the annual. The annual average surface temperature, annual average maximum (minimum) surface temperature and different climate zone showed significant warming trend, from the seasons, the most increase occurred in winter; from the different climatic zones, the warming trend was obvious in the plateau climatic zone of the annual average surface temperature and annual average minimum surface temperature, the annual average maximum surface temperature was observed in the north tropical zone. Annual average surface temperature, annual average maximum (minimum) surface temperature and different climate zone significantly mutated warming; among them, annual average surface temperature, annual average maximum (minimum) surface temperature marked mutation in 2000, 2004, 1997, respectively. The variation period was mainly long time scale of annual average surface temperature, annual average maximum (minimum) surface temperature and different climate zone; among them, the mainly variation period of annual average surface temperature, annual average maximum (minimum) surface temperature are 28 a, 26 a, 26 a, respectively. The annual average surface temperature, annual average maximum (minimum) surface temperature had significant negatively correlation with latitude and elevation; Asia polar vortex area (strength), Western Pacific deputy high west ridge point index significantly reduced, and the Western Pacific subtropical high pressure(extent, intensity, ridge line, north side), the India Burma trough, Tibet plateau, India subtropical high area index showed significant increase in 1961-2013, which may be the reasons for the surface temperature change of Yunnan Province.
