【摘要】 0601号台风“珍珠”具有强度强、路径怪异、影响范围广、来得早等显著特点。通过诊断分析发现,台风“珍珠”是1949年以来5月份登陆我国最强的台风之一,强度位于历史第3位;“珍珠”的路径在历史上是少见的,进入南海后,遇上了刚好到达华南和南海中北部海面的北方强冷空气,使得台风无法向北走,只能沿着冷空气的南边界,向西移动。后期,转受副热带高压的偏南气流引导,所以路径又转为北上。“珍珠”影响范围广,在不同程度上给广东、福建、江西、浙江、台湾等地都带来了很大的经济损失。“珍珠”形成前期,发源地的海温偏高、对流强盛以及冬春季青藏高原积雪偏少等导致了台风“珍珠”的异常偏早。更多还原

【Abstract】 The intensity of 0601 typhoon “Chanchu” is strong、the track of it is strange、the coming of “Chanchu” is early . By the diagnostic analysis, the result showed that “Chanchu” is one of the most early China Land falling typhoon in June, the intensity of “Chanchu” is the third from the June of 1949 to the June of 2006. the track of it is strange, when it comed to South China Sea, it is blocked by the strong cold wave of the in Mid-and North-Parts of south China sea and South China, so it move to the west. And the after stage, effected by the south airflow of Subtropical High,the “Chanchu” move to the north。Respond range of it is large , The economic loss of Guangdong、Fujian、Jiangxi、Zhejiang and Tailand are all with different density. Before the genesis stage of “Chanchu”, the SST in the region of origination is more high、the convection activity is severe and the below normal snow of the Winter and Spring over Qinghai-Xizang Plateau are all the reason which cause the earlier of “Chanchu”.更多还原
