Forecasters Handbook for the Philippine Islands and Surrounding Waters
Abstract
The analysis and forecasting of atmospheric and oceanic conditions important to air/ sea operations in the Philippine Islands area are described. The area covered includes the islands -- Luzon the Visayas (the central islands) and Mindanao -- from about 4.7 deg N to 21.5 N and 117 E to 127 E; and the Philippine Sea, Luzon Strait, South China Sea, and Sulu Sea. Seasonal climatologies of the southwest and northeast monsoons and tradewind regime, plus electromagnetic and ducting conditions, are presented. Appendices provide additional climatologies, a study of tropical cyclone characteristics, climatic normals for 60 Philippine stations, and percent frequencies of wave heights. Five case studies examine current accuracy of the Navy Operational Global Atmospheric Prediction System (NOGAPS) model analyses and prognoses. Tropical cyclone bulletins issued by the Joint Typhoon Warning Center, Guam, are identified and described; forecast philosophies are discussed. Interaction of Typhoon Yunya and the eruption of Mount Pinatubo volcano in June 1991 is described, and the dangers posed to aviation by volcanic ash are discussed.
