Intraseasonal oscillation intensity over the western North Pacific:Projected changes under global warming
摘要
Abstract
本文利用8个CMIP5模式的日资料,预估了RCP4.5和RCP8.5情景下全球增温达1.5℃和2.0℃时西北太平洋夏季30~60天和10~20天季节内振荡(ISO)强度的变化情况.大多数模式都认为,无论增温水平或情景如何,预估结果均显示从中南半岛南部到菲律宾以东的带状区域内ISO强度增加,并且关键气象要素背景的变化会对ISO强度异常的空间分布造成影响.具体表现为,ISO强度增大的区域往往伴随着低层湿度和湿静力能的增加.其中菲律宾东部的湿度变化最为明显,ICP南部的湿静力能变化最为明显,上述区域的ISO强度均增强.相反,印度尼西亚西部和菲律宾东北部有局地下沉运动增强,当地的ISO强度减小.关键词
