摘要
文章基于呼和浩特市1957—2012年自地面至高空20hPa的气温资料,统计分析了高空气温的季节变化、垂直分布、高空各层温度与地面温度变化的相关关系、长期变化趋势。结果表明:以150hPa层为界,其上部和下部的温度变化有着不同的特征,如在该层以下各层上的温度年较差为正值,而其上则为负值;近56a来,对流层下层温度显著增加,对流层上层和平流层的温度在降低,对流层温度直减率加大。
Based on the air temperalure data from the ground to the 20hPa during 1957-2010 in Hohhot, the seasonal changes, vertical distribution, the correlativity of air temperature changes between high-altitude each layer and ground, the long-term variation trend were statistically analyzed. The results showed that, there are different temperature variation characteristics in the upper and lower layer of 150hPa layer, such as, under the 150hPa layer, the annual range of each layer air temperature was positive value, over the 150hPa layer, it was negative value. In the past 56 years, the air temperature was obvious increases under the troposphere, but over the troposphere and stratosphere, the air tempeiature was decreased, the temperature lapse rate of tropospheric was increased.
