Abstract : The paper presents up-to-date climatological statistics on the frequency, intensity, movement and environmental conditions associated with tropical disturbances and tropical cyclones of the western North Pacific. Data summaries are stratified into annual and monthly averages for two periods 1900-1945 and 1946-1968, with more emphasis placed on the latter period. The study also presents both a physical description and dynamical interpretation of the tropical cyclone statistics. In addition, data summaries are presented of conditions associated with the maintenance and intensification of trade wind disturbances into tropical cyclones as observed by weather satellites. A section is included on analysis and forecasting techniques for tropical disturbances and tropical cyclone genesis and maintenance. (Modified author abstract)
