摘　　要：该文利用相关分析方法，研究了台风活动季节南北半球海平面气压与西北太平洋编号台风、登陆我国的台风和强台风频数的关系．对比分析了典型多、少台风年南北半球海平面气压的分布特征．指出秋、冬季节海平面气压与夏季海平面气压存在着隔季遥相关关系，并对台风活动的预报有很好的指示意义．通过回归集成，建立了预报编号台风、登陆台风、强台风发生频数的预报方程．文中还讨论了台风发生、发展的环境条件以及南北半球海平面气压影响台风活动的可能途径．he relationship between mean monthly Sea Level Pressure(SLP) distributions over Northern and Southern Hemispheres and formatting typhoon, landing typhoon and strong typhoon was studied using correlation analysis. The comparison of distributions of mean monthly SLP pattern between active and inactive typhoon years indicates that SLP distributions in the preceding autumn and winter were related with those in this summer. The possible affecting mechanisms of SLP on typhoon activities were discussed. A series of forecast equations associated with numbers of formatting typhoon, landing typhoon and strong typhoon were developed by regression integrated method. Furthermore, environmental conditions of genesis and development, and the possible ways of the influence of SLP over Northern and Southern Hemispheres on typhoons were also discussed.
