Abstract:

Xinyang 1961 through 2009, statistical analysis of temperature observations reveal the fact that global warming Xinyang. Linear regression analysis, moving average methods such as monthly mean temperature changes in diagnostic analysis, using non-parametric test (MK method) to the temperature trend in seasonal variation was tested. The results showed that: ① In the 1960s, the temperature fluctuations changed amplitude, the late 1960s had the lowest average annual temperature into the 1970s average temperature is rising, the average increase of about 0.027 ℃, and significant at 0.05 level; ② seasonal differences in temperature changed during the year. Order of successively decreasing temperature in winter, autumn and spring. Xinyang on the fact that global warming has made a positive response, nearly 49 years the average temperature increasing trend evident, particularly the recent increasing trend is accelerating.
