ABSTRACT

　　The purpose of this paper is aimed at discussing the development and movement of typhoons which occurred in October 1974. The interesting points are focused on the resemble characteristics of these typhoons as westward movement, deepenig near 120°E. After careful study, some conclusions are obtained. 1). Monsoon coupled with trade wind strengthened the easterly basic flow. 2) Monsoon transfering kinematic energy into low latitude caused the possibility of typhoon intensification.
