摘要:

本文是應(yīng)用100hPa北半球高度場(chǎng)格點(diǎn)資料,選取2003-2005年6-7月南亞高壓季節(jié)性東進(jìn)、北移的15個(gè)過(guò)程,其中包括這3年中在入、出梅期間500 hPa副熱帶高壓有響應(yīng)的季節(jié)性北移個(gè)例.計(jì)算了40 °N的波譜物理量-1～7波的方差比和波能密度,分析其西風(fēng)帶長(zhǎng)波-超長(zhǎng)波的調(diào)整和南亞高壓的東進(jìn)、北移的相關(guān),并從波能密度的演變特征來(lái)識(shí)別何種長(zhǎng)波波動(dòng)對(duì)南亞高壓的季節(jié)性變化具有最大的貢獻(xiàn).從而得出100hPa 40 °N的超長(zhǎng)波的調(diào)整是南亞高壓季節(jié)性東進(jìn)、北移的環(huán)流背景,而西風(fēng)帶4～6波的長(zhǎng)波槽波能密度的激增是誘發(fā)南亞高壓季節(jié)性演變的最大貢獻(xiàn)者.

Abstract:

In this paper, applying altitude field grid data of North Hemisphere at 100hPa , choosing 15 processes of south Asia high seasonal eastward and northward advances in June and July from 2003 to 2005,including example that subtropical high at 500 hPa had seasonal northward advance responding in entering and outing plum rain, the wave spectrum physics on 40 °N, the variance ratio of 1~7 waves and wave energy density are calculated. On the basis of this calculation, the responding relations between adjustment of long wave-extra-long wave within westerly belt and south Asia high eastward and northward advances are analyzed in order to recognize what kind of the long wave that made the most contribution to seasonal movement of south Asia high from the development feature of wave energy density. These analysis shows that the adjustment of extra-long wave on 40 °N at 100 hPa is the circumfluence background of south Asia high eastward and northward advances, the wave energy density increment of long wave groove from 4 to 6 waves within westerly belt made prominent contribution to seasonal development of south Asia high.
