Abstract:

利用逐日的NCEP再分析资料分析了1978~2004年期间发生的18次强爆发性增温时平流层中下层行星波1波和2波的异常以及极涡崩溃的形式.分析表明,爆发性增温前期1波都异常增幅,波振幅达到峰值之后的一段时间内发生爆发性增温,然而在增温过程中行星波2波的变化却有明显不同,可分为三种情况:(1)在增温前期,行星波2波很弱;在增温期间,行星波2波异常发展,伴随着极涡崩溃的形式是由偏心型向偶极型过渡.(2)在增温前期,行星波2波较强;在增温期间,行星波2波明显减弱,极涡的变化形式是远离极地,在极地外围活动,但不发生分裂.(3)在增温前期,行星波2波不太强;在增温期间,行星波2波有所发展,但始终强不过1波,极涡的变化是先偏离极地,然后发生不对称的变形.作者还计算和分析了EP通量及其散度,利用波流相互作用理论对这三种行星波的异常变化及其与爆发性增温的关系进行解释.
