摘要
海陆热力差异是季风形成和演变的根本驱动力,青藏高原与印度洋热力差异是影响南亚季风活动的重要因素。本文围绕次季节、季节、年际和年代际等不同时间尺度上青藏高原与印度洋的热力差异对南亚季风活动的影响,回顾和总结了相关研究成果。在次季节尺度上,主要聚焦在两者的热力差异对南亚季风爆发的影响;在年际尺度上,着重阐释了其对南亚季风强度年际变化的指示意义;在年代际尺度上,考察了热力差异和南亚季风降水关系的年代际变化。同时,本文对该领域一些需要进一步研究的问题进行了讨论。
Land-sea thermal contrast is the fundamental driving force for the onset and evolution of the Asian summer monsoon.The Tibetan Plateau-Indian Ocean thermal contrast is a crucial factor influencing South Asian monsoon activity.This article reviews and summarizes relevant research results on the effects of the Tibetan Plateau-Indian Ocean thermal contrast on South Asian monsoon activity on various time scales,including subseasonal,seasonal,interannual,and interdecadal scales.On the subseasonal scale,the main focus is on the influence of thermal contrast on the onset of the South Asian monsoon.On the interannual scale,emphasis is placed on the indicative significance of the thermal contrast concerning the interannual variation in monsoon intensity.On the interdecadal scale,the interdecadal variations in the relationship between the thermal contrast and South Asian monsoon precipitation are examined.This article discusses some issues that require further research in this field.
