Comparisons of the Circulation Anomalies Associated with Extreme Heat in Different Regions of Eastern China

摘要: AbstractThe circulation associated with extreme heat (EH) typically shows an anomalous anticyclone that enhances temperature through adiabatic heating, but this study indicates obvious spatial variation in eastern China. The EH-related pattern China can be classified into three categories: typical extratropical pattern, monsoonal and foehn pattern. EH over northeastern north is characterized by a involving subsidence, the air increases throughout almost entire troposphere. In contrast, Yangtze River valley south Over these regions, only lower troposphere as result of subsidence humidity has resulted from farther transportation water vapor stronger southwesterly. Meanwhile, decreases upper because ...
