Abstract:

In order to further study on some disaster weather variation under the background of climate warming of Shanxi southeastern regions, using the temperature data of 11 meteorological observation stations in southeast Shanxi during 1971-2010, the author analyzed the average annual temperature, obtained the fact of climate warming, the average annual temperature rise speed was 0.3℃/10 a. Then, the author compared year, season mean temperature with arid event, cold wave, high temperature days tendency evolution, drew the conclusion: the climate warming were the primary cause for the disaster weather mutation. Along with age average temperature's rise, the arid event times increased; along with the rise of annual temperature tendency, the cold wave times reduced, its speed reduced was 4.8 times/10 a, the autumn temperature rise caused the cold wave initial period postponed, the autumn temperature's rise speed was 0.23℃/10 a, the cold wave delay rate was 15 d/10 a; the spring temperature rise made the cold wave finishing period to be ahead of time, spring temperature rise speed was 0.3℃/10 a, cold wave advance speed was 10 d/10 a; The high temperature date number was consistent with the summer age temperature's change tendency, from the 80s, along with age temperature rise, the high temperature days increased obviously.
