AEROGRAPHER'S MATE 3 & 2 



particularly with respect to observing and ex- 

 changing coded information reflecting the sys- 

 tem's continuously changing state. The U.S. 

 Navy is an active participant in the World 

 Meteorological Organization (WMO), an organiza- 

 tion of international cooperation in meteorology. 



NAVAL WEATHER UNITS 



To carry out their assigned functions, weather 

 units ashore and afloat are maintained with all 

 major aviation units on certain types of com- 

 batant and auxiliary vessels, on certain fleet 

 flagships, and at other naval activities ashore. 



The trained enlisted and commissioned me- 

 teorological personnel assigned to a particular 

 ship or station comprise the naval weather unit. 



Detailing Aerographer's Mates to each ship 

 or station is performed by the Bureau of Naval 

 Personnel. The number of personnel provided 

 to each naval weather unit depends upon the op- 

 erational requirements placed upon the unit. 

 The number of hours per day during which me- 

 teorological services must be available is a 

 particularly important factor in determining per- 

 sonnel requirements. 



WEATHER UNITS ASHORE 



There are five basic types of weather units 

 ashore: 



1. Fleet Numerical Weather Central. 



2. Fleet Weather Centrals. 



3. Fleet Weather Facilities. 



4. Naval Weather Service Facilities. 



5. Naval Weather Service Command Detach- 

 ments. 



The centrals and facilities are structured to 

 provide, collectively, global fleet support. 



Fleet Numerical Weather 

 Central (FLENUMWEACEN) 



The Fleet Numerical Weather Central, 

 Monterey, CA, is the operational hub of the 

 Naval Weather Service (NAVWEASERV) system. 

 It is globally-oriented to generate basic numeri- 

 cal (computer) products in support of the entire 

 NAVWEASERV system and from which specific 

 fleet support products and services are de- 

 rived. 



Fleet Weather Central 

 (FLEWEACEN) 



The Fleet Weather Centrals utilize the basic 

 numerical products to provide specific fleet 

 environmental support (less the polar regions). 

 This support includes the fleet environmental 

 broadcasts, as well as that support in response 

 to specific requests by the operating forces. 

 Each FLEWEACEN is oriented to a major ocean 

 basin area. 



Fleet Weather Facility 

 (FLEWEAFAC) 



Fleet Weather Facilities, within assigned local 

 and/or functional areas of responsibility, sup- 

 plement the direct fleet support provided by 

 the FLEWEACENs. For example, FLEWEAFAC 

 Suitland, MD, is oriented primarily to provide 

 fleet environmental support in the polar regions, 

 particularly sea ice forecasting, and to pro- 

 vide global meteorological satellite analysis and 

 interpretation support to the FLEWEACENs. 



Naval Weather Service Facility 

 (NAVWEASERVFAC) 



Naval Weather Service Facilities are oriented 

 primarily to management functions, although they 

 also provide local and aviation fleet forecast 

 services. They command NAVWEASERV detach- 

 ments and manage selected technical programs, 

 thus permitting FLEWEACENs and FLEWEA- 

 FACs to concentrate more completely on op- 

 erational support services. 



Detachments of the 

 Naval Weather Service 



Detachments are established to provide lo- 

 cally-oriented support at stations and air sta- 

 tions, and to perform specific technical functions 

 in support of the NAVWEASERV system. 



NAVAL WEATHER SERVICE ENVIRONMEN- 

 TAL DETACHMENT (NWSED). — NWSEDs are 

 established under an Officer in Charge or Chief 

 Petty Officer in Charge who reports to a des- 

 ignated NAVWEASERV central/facility. They are 

 oriented to provide direct environmental sup- 

 port, including aviation and oceanographic serv- 

 ices, within their local areas. 



Detachments assigned to NAVWEASERVFAC 

 Pensacola, FL, are oriented toward support of
