摘要:

利用ERA-Interim和MERRA-2再分析资料,考察1980—2017年青藏高原大气温度变化趋势和规律,年、季、月不同时间尺度分析结果均揭示2008年以来青藏高原春季大气温度变化呈现逆转趋势:高原上空平流层下部150~50 hPa呈现明显的增温趋势(1.0~2.7℃/10a),对流层上部300~175 hPa呈现明显的降温趋势(-3.1~-1.0℃/10a),这与此前的大气温度变化趋势完全相反。利用TOMS和OMI卫星臭氧遥感资料,考察同期青藏高原臭氧总量变化特征,表明2008年以来青藏高原臭氧总量也表现出逆转的增加趋势,与大气温度逆转趋势吻合,从冬末至春季各月均有显著增加趋势,尤以5月臭氧总量增加速率最大,达13.7 DU/10a。青藏高原春季大气温度变化趋势与同期臭氧总量变化特征紧密相关,2008年后臭氧总量的快速恢复可能是引起大气温度逆转趋势的一个重要影响因素。

Abstract:

Trends of atmospheric temperature during 1980-2007 over the Tibetan Plateau were evaluated using the ERA-Interim and MERRA-2 reanalysis data sets. Analyses of different time scales from annual to seasonal and monthly show that remarkable reversal trends of atmospheric temperature after 2008: temperatures at the lower stratosphere (150-50 hPa) are increasing with rates of 1.0-2.7℃/10a, while in the upper troposphere (300-175 hPa), temperatures are decreasing with rates of -3.1- -1.0℃/10a. Trends of atmospheric temperature in spring after 2008 over the Tibetan Plateau are reversal with those of 1980-2007. Analysis of total ozone trends over the Tibetan Plateau during 1980-2017 were carried out and results show significant increasing trends of monthly total ozone from end of winter to spring, especially in May with the highest increasing rate of 13.7 DU/10a. Analysis results show that variations of atmospheric temperature are closely linked with variation of total ozone, and the reversal trends of atmospheric temperature in spring maybe the results of total ozone recovery after 2008 over the Tibetan Plateau.
