 areas of responsibility. 



The Navy Fleet Weather Centrals and Facilities 

 have operational oceanographic divisions, manned 

 by personnel trained in both meteorology and 

 oceanography. Fleet Weather Centrals and Facili- 

 ties, acting as regional operational oceanographic 

 support centers, provide technical guidance to 

 Naval Weather Service Environmental Detach- 

 ments (NWSED's) and mobile oceanographic 

 teams aboard ships in order to help tailor their 

 services to the user's needs. 



The Navy operates Fleet Weather Facilities at 

 Yokosuka, Japan; Sangley Point, Phillippine 

 Islands; San Diego, California; Jacksonville, 

 Florida; Quonset Point, Rhode Island; Kodiak, 

 Alaska; Argentia, Newfoundland; Keflavik, Ice- 

 land; and London, England as specialized centers. 

 These Facilities provide forecasts and warnings 

 tailored to specific naval operating and training 

 areas. Many Fleet Weather Facihties and Weather 

 Centrals have other specific responsibiUties: 



Argentia and Kodiak provide ice forecasting serv- 

 ices; Alameda and Norfolk operate the Navy's 

 Optimum Track Ship Routing Program (this pro- 

 gram provided routing services for 3980 DOD 

 ships in 1967). Guam is the site of a joint 

 Navy/ Air Force typhoon warning center. All activ- 

 ities of the Integrated Fleet Weather Central 

 System participate in the Anti-Submarine Warfare 

 Environmental Prediction System (ASWEPS). 



The Fleet Numerical Weather Central (FNWC), 

 Monterey, California is the center of the weather 

 and oceanographic data-processing computer net- 

 work; it is also the center for computer program 

 development for the Naval Weather Service Com- 

 mand. FNWC issues operational analyses/forecasts 

 covering thermal structure, sound-speed structure, 

 wave conditions, and surface currents in support of 

 fleet operations. 



The most significant FNWC forecasting activi- 

 ties are the thermal structure programs for the
