Abstract:

The consistency and local characteristics of the temperature in Northeast China were studied using the surface temperature data from 162 stations in Northeast China from 1961 to 2015.The results show that there is good spatial consistency in the annual average temperature in Northeast China.The region-wide consistent climate pattern is the most important climate pattern of the region.The time coefficient of the first rotation load vector shows an upward trend and there is also a significant 2-7 years periodicity,indicating that the temperature in the northern region is significantly affected by global warming,ENSO (El Niño-Southern Oscillation),and another large-scale climatic background.The temperature increasing rate in the northern region is 0.34 ℃ per decade from 1961 to 2015,which is higher than that of 0.26 ℃ per decade in the southern region,while the increasing trend slows down after 1980.The probability curve of annual average temperature moves to the high-value area with time.Significant warming appears in winter in the northern region,and in both winter and summer in the southern region,which indicates that the length of spring and autumn may be short.
