摘要:

本文通過(guò)一系列敏感性試驗(yàn)探究臺(tái)風(fēng)"煙花"移動(dòng)緩慢的可能機(jī)理。結(jié)果表明:臺(tái)風(fēng)"煙花"的移動(dòng)對(duì)臺(tái)風(fēng)"尼伯特"的強(qiáng)度較為敏感。"尼伯特"強(qiáng)度主要通過(guò)影響其附近大尺度低壓系統(tǒng)的強(qiáng)度與范圍,間接影響"煙花"的大尺度引導(dǎo)氣流,進(jìn)而影響"煙花"的移動(dòng)。具體而言,"尼伯特"與其附近大尺度低壓系統(tǒng)環(huán)流共同激發(fā)西北風(fēng)引導(dǎo)氣流,抵消了部分副高西南側(cè)的東南風(fēng)引導(dǎo)氣流,從而造成"煙花"受到的大尺度引導(dǎo)氣流偏弱,致使其移動(dòng)緩慢,路徑復(fù)雜。此外,當(dāng)"尼伯特"強(qiáng)度越大時(shí),以上過(guò)程對(duì)"煙花"移動(dòng)的影響也越大。因此,當(dāng)兩個(gè)臺(tái)風(fēng)相距較遠(yuǎn)時(shí),雙臺(tái)風(fēng)相互作用可能通過(guò)影響周?chē)拇蟪叨认到y(tǒng),間接對(duì)臺(tái)風(fēng)路徑產(chǎn)生較大影響。

Abstract:

This study employed a series of sensitivity experiments to investigate the potential mechanisms of the slow movement of Typhoon "In-fa". The findings show that the movement of Typhoon "In-fa" is influenced by the intensity of Typhoon "Nepartak". The intensity of "Nepartak" mainly affects the strength and range of the nearby large-scale low-pressure system, indirectly affecting the large-scale guiding airflow of "In-fa" and then affects its movement. In particular, the northwest wind-steering flow generated by "Nepartak" and low-pressure system partially neutralizes the southeast wind-steering flow on the southwest side of the subtropical high. This neutralization leads to the reduction in the large-scale steering flow of "In-fa", resulting in its slow movement and a complex track. Moreover, the study points out that the stronger "Nepartak" is, the greater its influences on movement of "In-fa" are. Results emphasize that interaction between distant typhoons can indirectly affect typhoon tracks by influencing the large-scale systems in its vicinity.
