中文摘要: 利用南半球海平面气压场格点资料，通过差值场和相关分析，研究了南半球大气环流对华南前汛期降雨的影响。结论指出，无论是同期还是前期，华南前汛期多雨年和少雨年所对应的南半球大气环流系统基本呈反相，两者之间存在密切关系。还就澳大利亚高压、马斯克林高压、南美对流活跃区等对华南前汛期降雨影响的可能机理进行了初步分析。首次讨论了澳大利亚高压强度与影响华南的南海西南季风强度之间反相关的有趣事实。
Abstract:By using the solenoid fields data of sea level pressure over Southern hemisphere,through the difference value fields and correlation analysis,the influence of general circulation of atmosphere over Southern hemisphere on precipitation over South China during pre flood season have been analyzed.The results show that the general circuation of atmosphere systems over the Southern hemisphere are basically out of phase for drought and waterlogging years,in same term or earlier stage.The influence mechanism of Australia anticyclone,Mascarene anticyclone and convective active region of South America have been preliminary analyzed.The significant fact of the anticorrelation relationship between the Australia anticyclone intensity and SW monsoon in South Sea affecting South China have been researched for the first time.
