摘要
本文在定义台风潜在破坏力(TYDP)、台风破坏时间(TYDT)和台风潜在破坏强度(TYDS)基础上,利用中国气象局上海台风所整理的最优路径数据集资料,分析了南海和西北太平洋上三者的分布特征和变化特征。结果表明:台风破坏力和破坏时间主体分布在南海中北部、台湾岛和菲律宾以东的西北太平洋;主要集中在下半年,高峰月主要分布在9月、8月或10月,南海各区台风活动期长度和高峰月有明显差异;南海和西北太平洋区域台风潜在破坏力、破坏时间及破坏强度主体呈减小(少、弱)趋势,但存在一定的空间差异;台风破坏强度减弱倾向的空间一致性较好,南海和西北太平洋区域的东西两侧呈微弱的增强趋势。
This article defined the typhoon destruction potential （TYDP）, typhoon destruction time （TYDT） and typhoon destruction strength （ TYDS ）. Based on the typhoon data （ 1949--2014 ） from the China Meteorological Administration, the spatial distribution, monthly distribution, and variation characteristics of them over the South China Sea （SCS） and the Northwest Pacific （WNP） were analyzed. The results showed that TYDP and TYDT mainly distributed in the north-central part of the south China sea and east of Taiwan and the Philippines, and mainly concentrated in the second half of the year, with the peak appearing on August, September, or October. The typhoon active season duration and peak months varied greatly among different areas of SCS. TYDP,TYDT and TYDS decreased （weakened） as a whole on SCS and WNP from 1949 to 2014, though there were some spatial differences. The weaken trend of TYDS had better spatial coherency comparing with TYDP and TYDT, with tiny strengthen trend over east and west wing of the study area.
