摘　　要：采用日本气象厅(JMA)东京台风中心(RSMC-Tokyo)发布的1951~2015年西北太平洋台风最佳路径数据集,对影响中国广东沿海地区的台风进行了统计与分析。结果表明:65年间影响到广东沿海的台风共计300次,年均4.6次,较多的年份达到10次,较少的只有1次,每年第一次影响广东沿海台风的生成时间主要在7月前后,最早到4月份,最迟到9月份;其源地均位于赤道以北,主要分布在10°N附近、120°~150°E之间;在广东沿海登陆的台风每年在3次左右,主要集中在都在7~9月,只有极少部分出现在4、5、11月,而临近台风年均在1.5次左右,其分布的时间较分散,除1、2月外几乎全年都有出现;影响到广东沿海的台风主要以超强台风为主,占总数的49%。In this paper, typhoons affecting the coastal areas of Guangdong Province were analyzed by using the best path data set of typhoons over the Northwest Pacific Ocean from 1951 to 2015 published by the Tokyo Typhoon Center （RSMC-Tokyo） of Japan Meteorological Agency （JMA）. The results show that there are 300 typhoons affecting the coastal areas of Guangdong Province in the past 65 years, with an average of 4,6 typhoons per year, ranging from 1-10 typhoons in a year.The onset time of the first typhoons affecting Guangdong coastal areas every year is mainly around July, the earliest time of which is April and the latest is September.The cradle is located in the north of the equator, mainly distributed near 10 ° N, 120-150 ° E.Ty- phoons landing along the coast of Guangdong occur about three times a year, mainly from July to September, and only a few of them occur in April, May, and November. The approaching typhoons are about 1.5 times a year, and the distribution time of them are dispersed, occurring almost all year except January and February. Besides, typhoons affecting the coast of Guangdong are mainly super typhoons, accounting for 49% of the total.
