摘要

利用1949—2010西北太平洋热带气旋最佳路径数据集,分析了西北太平洋热带气旋的时空分布特征,结果发现: 1) 62 a来西北太平洋生成的热带气旋和登陆我国的热带气旋年频次呈下降趋势,热带低压下降的趋势尤为明显; 2) 热带气旋平均生成位置随着月份变化呈现季节移动规律,纬度上有明显北移趋势; 3) 热带气旋中心气压低值和最大风速高值主要集中在南海盆地和菲律宾海以东洋面区,热带气旋前移速度分布具有显著纬度地带性.

Abstract

The spatiotemporal characteristics of the tropical cyclone in Northwest Pacific basin are analyzed from TC best-track datasets of NWP between 1949 and 2010. It was found that that the tropical cyclone in Northwest Pacific basin and those that have landed in China experienced a statistically significant decrease trend from 1949 to 2010, the percentages of the tropical depression specially had an greater downward trend. The genesis location of tropical cyclone changed with season, the average genesis latitude increased in the passed 62 years, which meant more cyclones were formed at higher latitude. Low value of central pressure and high value of maximum wind speed were mainly concentrated in the South China Sea and in the east of the Philippine Sea. Distribution of forward direction and forward velocity of the tropical cyclones showed a significant latitude zone pattern.
