【摘要】 本文就我们5年来在下垫面强迫对东亚区域气候影响方面的研究进行了总结。这些工作包括青藏高原、陆面过程及热带西太平洋热源异常对短期气候变化影响的数值试验研究，积雪、地温及海温等下垫面状况与短期气候变化关系的分析研究，以及在特征地质时期的边界条件下对东亚古气候的数值模拟。这些研究从不同角度强调了下垫面强迫作用在东亚区域气候形成、变化中的重要性。更多还原

【Abstract】 This paper reviews our the last five years’ research on the influence of underlying surface forcing on the regional climate in East Asia. These studies include the numerical experiments on the impact of heat source anomalies in the Tibetan Plateau, land surface processes and the western tropical Pacific on short-term climatic variaton, statistical analyses of the relationship between land snow cover, soil temperature and sea surface temperature, and short-term climatic variations, and numerical simulations under the boundary conditions of typical geological periods. All the work emphasizes the importance of forcing action of underlying surface in the formation and variation of East-Asia regional climate.更多还原
