摘要:

利用NCEP提供的0.25°×0.25° FNL資料和國家氣象信息中心提供的高分辨率三源融合降水資料,以臺(tái)風(fēng)"利奇馬"為研究個(gè)例,從動(dòng)力和熱力因素兩個(gè)方面研究了中緯度高空槽與臺(tái)風(fēng)之間的相互作用對(duì)臺(tái)風(fēng)遠(yuǎn)距離暴雨的影響。研究認(rèn)為中緯度高空槽—臺(tái)風(fēng)的相互作用是此次臺(tái)風(fēng)遠(yuǎn)距離暴雨的主要原因之一。在高空槽—臺(tái)風(fēng)的相互作用中,隨著弱正PV異常從中緯度高空槽向臺(tái)風(fēng)區(qū)域的水平平流,臺(tái)風(fēng)西北部地區(qū)逐步處于高空槽前西南急流的次級(jí)環(huán)流的上升區(qū)域,而對(duì)流層深厚的暖平流恰好位于臺(tái)風(fēng)西北部3~5個(gè)緯距的地區(qū),此熱成風(fēng)暖平流的作用增強(qiáng)了臺(tái)風(fēng)西北地區(qū)的上升運(yùn)動(dòng)。另外,中緯度高空槽后的干冷空氣的逼近,促進(jìn)了在臺(tái)風(fēng)西北部地區(qū)的中緯度斜壓鋒生,斜壓鋒面進(jìn)一步增強(qiáng)了臺(tái)風(fēng)遠(yuǎn)距離暴雨處的動(dòng)力抬升作用。同時(shí)還發(fā)現(xiàn)當(dāng)臺(tái)風(fēng)與中緯度槽的距離大約是10個(gè)緯距時(shí)其相互作用最為顯著。

Abstract:

By using the 0.25°×0.25° FNL data provided by NCEP and the high-resolution three-source merged precipitation data provided by National Meteorological Information Center, the interaction between the mid-latitude upper trough and Lekima (1909) on remote heavy precipitation was investigated involved dynamic and thermal processes. The interaction between the mid-latitude upper trough and Lekima (1909) is considered as one of the main reasons for the remote heavy precipitation. In the interaction between the mid-latitude upper trough and typhoon, the northwest of typhoon is gradually located in the ascending area of the southwesterly jet in front of the trough as the weak positive Potential Vorticity (PV) anomaly is advected horizontally from the mid-latitude upper trough to typhoon. The deep tropospheric warm advection is located in the area of 3°-5° to the northwest of typhoon, which enhances the ascending motion at the northwest of typhoon. In addition, the approach of dry and cold air behind the upper trough promotes the middle-latitude baroclinic frontogenesis at the northwest of typhoon, which further enhances the dynamic uplift of the typhoon at remote heavy precipitation area. Furthermore, the interaction between typhoon and mid-latitude upper trough is the most significant when their distance is about 10°.
