摘要: 基于1961—2024年山西省国家气象观测站气温、ERA5再分析资料和卫星反演气溶胶等资料,对山西省近60 a气温变化的季节差异进行了分析,并探讨了最大升温季节由冬季转变为春季的可能成因。结果表明:20世纪90年代之前,山西省冬季平均气温升温速率最快,明显高于其他季节,20世纪90年代中期之后升温减缓,春季平均气温升温速率超过冬季,成为升温速率最快的季节;前期(1961—1990年)最低气温的显著升高是冬季快速变暖的主要驱动者,近期(1995—2024年)最低和最高气温的上升同为春季加速升温的主要贡献者;影响山西省冬、春季升温速率变化的主导因子不同,春季土壤湿度的减少及其正反馈作用,增强了土壤对近地面大气的加热,从而使得升温加速,冬季升温速率放缓主要受西伯利亚高压年代际增强影响。

Abstract: Based on monthly temperature data from national meteorological observation stations,ERA5 reanalysis data,and aerosol optical depth data derived from satellite,this study analyzes the seasonal warming differences in Shanxi Province over the period 1961-2024 and identifies the possible causes of seasonal change in the maximum warming from winter to spring.The results indicate that:the rate of warming was highest in winter and significantly exceeded that of other seasons prior to the 1990s.Winter warming has slowed,while the rate of warming in spring has surpassed that of winter,making spring the season with the most rapid temperature increase since the mid-1990s.The pronounced rise in minimum temperature during the early period (1961-1990) was the primary driver of rapid winter warming,whereas in the recent period (1995-2024),both minimum and maximum temperatures contributed significantly to the accelerated warming in spring.The dominant factors affecting the warming change in winter and spring are different:an accelerating spring warming was driven by the persistent decline in soil moisture and its positive feedback,and the weakened winter warming was induced by the strengthened intensity of the winter Siberian High.

Key words: Warming rate, Seasonal differences, Soil moisture, Siberian High
