Abstract

This paper is designed to be an annual summary of the Eastern Hemisphere tropical cyclones of 1995. The tropical cyclone statistics presented are those of the Joint Typhoon Warning Center, Guam. The text focuses primarily upon the tropical cyclones that occurred in the western North Pacific during 1995; however, since the area of responsibility of the Joint Typhoon Warning Center covers the entire Eastern Hemisphere, brief summaries of the tropical cyclone activity within the north Indian Ocean, south Indian Ocean, and the southwest Pacific are also presented. Overall, 1995 was a relatively quiet year in the Eastern Hemisphere: the 22 tropical cyclones of the Southern Hemisphere were only one shy of the record low of 21, and for the first time since 1988 the number of tropical storms and typhoons in the western North Pacific was below normal. In the western North Pacific, there was a marked shift to the west of the preferred region for the genesis and development of tropical cyclones. This is consistent with the end of persistent large-scale circulation anomalies characteristic of the warm phase of the El Niño–Southern Oscillation (ENSO) and the onset (during 1995) of weak ENSO cold-phase anomalies (i.e., La Niña conditions).
