The Annual Tropical prepared by the staff of Warninq Center (JTWC), a Cyclone Report is the Joint Typhoon combined USAF/USN organi~ation operating under the command of the Commanding Officer, U. S. Naval Oceanography Command Center/ Joint Typhoon Warning Center, Guam. JTWC was established in April 1959 when USCINCPAC directed USCINCPACFLT to provide a single tropical cyclone warning center for the western North Pacific region. The operations of JTWC are guided by CINCPACINST 3140.1 (series).
The mission of the Joint Typhoon Warning Center is multi-faceted and includes:
1. Continuous monitoring of all tropical weather activity in the Northern and Southern Hemispheres, from 180 degrees longitude westward to the east coast of Africa, and the prompt issuance of appropriate advisories and alerts when tropical cyclone development is anticipated.
2. Issuing warnings on all significant tropical cyclones in the above area of responsibility.
3. Determination of reconnaissance requirements for tropical cyclone surveillance and assignment of appropriate priorities.
4. In depth post-storm analysis of all tropical cyclones occurring within the western North Pacific and North Indian Oceans for publication in this report.
5. Cooperation with the Naval Environmental Prediction Research Facility, Monterey, California, on the operational evaluation of tropical cyclone models and forecast aids, and the development of new techniques to support operational forecast scenarios.
Satellite imagery used throughout this report represents data obtained by the tropical cyclone satellite surveillance network. The personnel of Detachment 1, lWW, colocated with JTWC”at Nimitz Hill, Guam, coordinate the satellite acquisitions and tropical cyclone surveillance with the following units:
Det 5, lWW, Clark AB, RP
Det 8, lWW, Kadena AB, Japan Det 15, 30WS, Osan AB, Korea
Det 4, lWW, Hickam AFB, Hawaii
Air Force Global Weather Central, Offutt AFB, Nebraska
In addition, the Naval Oceanography Command Detachment, Diego Garcia, and DMSP equipped U.S. Navy aircraft carriers have been instrumental in providing vital satellite position fixes of tropical cyclones in the Indian Ocean.
Should JTWC become incapacitated, the Alternate Joint Typhoon Warning Center (AJTWC) located at the U. S. Naval Western Oceanography Center, Pearl Harbor, Hawaii, assumes warning responsibilities. Assistance in determining satellite reconnaissance requirements, and in obtaining the resultant data, is provided by Det 4, lWW, Hickam APB, Hawaii.
