摘要
9005号台风北上时间比常年早,到达位置偏北,造成山东东南沿海暴风雨天气过程,主要影响因素是:西太平洋副热带高压西向脊线偏北;河西—河套地区高空西风环流较平直,利于台风西行—北上.台风路径预报可从太平洋副高西向脊线位置、高空环流形势和台同母体云系长轴方向三个方面综合分析.
Typhoon No. 9005 passed of Qingdao coast on the Yellow Sea and brought a pouring storm to the southeast part of Shandong Province after it swept East China coastal area on landing at Fujian Province on June 24,1990. It is an unusual case of typhoon-moving toward North China coast earlier and farther north in latitude than in most years past. The factors contributing to such a case are probed. It is revealed that the strong north-and west-advance of the typhoon was due to the fact that at the time the westerly West Pacific subtropical high ridge line lay north of normal position and the part of westerly wind cell over Hexi-Hetao area was somewhat flat. The observations of typhoon No. 9005 suggest that the forecast of the course of typhoon should be based on the comprehensive analysis of three elements;the position of westerly West Pacific subtropical high ridge line,the situation of westerly wind cell and the direction of macro-axix of cloudy cluster of typhoon.
