Ref:    (a) OPNAV Instruction 3140.17E of 29 October 1965
        (b) SECNAV Instruction 5600.16 of 2 November 1960

1.    The Annual Typhoon Report, 1965, is submitted herewith in accordance with reference (a).

2.    During calendar year 1965, a total of 21 typhoons, 13 tropical storms and six tropical depressions occurred in the Western Pacific area between 180°E longitude and the Malay Peninsula, north of the equator. There were 805 warnings issued in this area in 1965. A new record of 167 calendar days in warning status was established in 1965.

3.    Reference (a) directed the Fleet Weather Centrals at Pearl Harbor and Alameda to forward summaries of tropical cyclones in their areas to Fleet Weather Central/Joint Typhoon Warning Center Guam for inclusion in the subject report. Fleet Weather Central Alameda issued a total of 241 warnings on one hurricane, nine tropical storms and two tropical depressions in their area of responsibility. One of these tropical storms (DOREEN) crossed to the west of 140°W and Fleet Weather Central Pearl Harbor issued three warnings on this cyclone. A complete summary of tropical cyclones east of 180 degrees longitude is included in Annex A.

4.    One interesting fact of the 1965 typhoon season was that a record number of "super typhoons" (i.e., sustained surface winds of 130 knots or more) occurred in the FWC/JTWC Guam area of responsibility. There were 11 typhoons in this category which surpassed the previous record of eight.

5.    This report has been reviewed and approved in accordance with reference (b).

FOREWARD

   This report is published annually and summarizes Western North Pacific Tropical Cyclones. Effective this year. Annex A is added to summarize Tropical Cyclones from 180 degrees eastward to the North American Coast.

   When directed by CINCPAC in May 1959, CINCPACFLT redesignated Fleet Weather Central Guam as Fleet Weather Central/Joint Typhoon Warning Center (FWC/JTWC), Guam with the following responsibilities:

1.    To provide warnings to U. S. Government agencies for all tropical cyclones west of 180 degrees longitude north of the equator to the Asiatic coast and Malayan Peninsula.

2.    To determine tropical cyclone reconnaissance requirements and assign priorities.

3.    To conduct Investigative and post analysis programs including preparation of the Annual Typhoon Report.

4.    To conduct tropical cyclone forecasting and detection research as practicable.

   Fuchu Air Force Weather Central, coordinating with Fleet Weather Facility Yokosuka was designated as alternate JTWC in case of failure of FWC/JTWC Guam.

   The JTWC, which is an integral section of FWC/JTWC Guam, is staffed by three Air Force and three Navy meteorologists and three enlisted men from each service. The senior Air Force Officer has been designated as the Director, JTWC.

   The Joint Hurricane Warning Center in Hawaii, a coordinated agency composed of the U. S, Weather Bureau, Honolulu, the Air Force Kunia Weather Center, and Fleet Weather Central Pearl Harbor, is responsible for surveillance and issuance of warnings in the Central North Pacific area north of the equator between 180 degrees and 140 degrees west.

   The Fleet Weather Central, Alameda, California, is responsible for issuance of warnings between 140 degrees west and the North American Coast.
