一九八三年,西北太平洋的台风活动,有三个明显的特点:一是第一个台风出现的时间晚。正常年份,5月以前便有台风生成,而1983年1—5月份均无台风生成,第一个强台风生成的时间在7月11日,这是近35年来,台风出现最晚的一年。二是间歇期长。从1982年12月8日至1983年6月25日共200天在西北太平洋无台风生成,在历史上是少有的。三是台风少。历年1—9月份平均有20个台风生成,多的年份有32个,而1983年1—9月份只有11个台风生成,是最近35年的最低值。 In 1983, there were three distinct characteristics of typhoon activity in the western North Pacific. First, the first typhoon appeared late. In normal years, typhoons were generated before May and no typhoon was generated in January-May 1983. The first strong typhoon was generated on July 11, the latest one in the past 35 years . Second, intermittent long. There are no typhoons in the western North Pacific since 200 days from December 8, 1982 to June 25, 1983, and rare in history. Third, fewer typhoons. In the first nine months of this year, there were an average of 20 typhoons generating, 32 more years, compared with 11 typhoons in January-September 1983, the lowest in 35 years.
