Chapter 17 — ADMINISTRATION, PUBLICATIONS, AND SUPPLY 



Naval Air Training. SimUarly, the detachments 

 assigned to NAVWEASERVFAC Glenview, IL, 

 primarily support the Naval Air Reserve pro- 

 gram. Detachments providing data support and 

 liaison functions primarily are assigned to 

 FLENUMWEACEN Monterey, CA. 



NAVAL WEATHER SERVICE DETACHMENT 

 (NWSD). — NWSDs are oriented to provide spe- 

 cific technical support of the NAVWEASERV sys- 

 tem. For example, NWSD Asheville.NC, provides 

 climatological support to the Naval Weather Serv- 

 ice. NWSD Asheville, NC, is under the command 

 of FLEWEAFAC Suitland, MD. 



NAVAL WEATHER SERVICE 

 METEOROLOGICAL UNITS 



Naval Weather Service Meteorological Units 

 composed of varying numbers of meteorological 

 personnel are assigned to staffs, ships, and 

 activities according to the specific requirements 

 for environmental support. These units are nor- 

 mally integral components of the commands to 

 which they are assigned, and they are staffed 

 and equipped in accordance with their desig- 

 nated functions. 



PARTICIPATING UNITS 



Ships, aircraft squadrons, and some shore 

 activities to which no meteorological personnel 

 are assigned are also elements of the Naval 

 Weather Service in that they are direct con- 

 tributors of environmental observations. The 

 NAVWEASERV provides technical guidance and 

 direction in the observing and reporting pro- 

 cedures to be employed by these units. 



OBSERVATIONAL PROGRAMS 



Requirements for taking environmental ob- 

 servations emanate from obligations to the De- 

 partment of Defense, the Department of the Navy, 

 and from agreements of mutual benefit between 

 national and international agencies. NAVWEA- 

 SERVCOMINST 3140.1( ) provides the minimum 

 requirements for taking and recording observa- 

 tions by Navy and Military Sealift Command 

 (MSC) ships. 



Such additional and special weather and 

 oceanographic observations and reporting sched- 

 ules as may be required in support of fleet 

 operations are promulgated in pertinent operation 



plans and orders. Requirements for increased 

 frequency of weather reporting by ships at sea 

 in specific areas, particularly in areas where 

 tropical disturbances are suspected or known 

 to exist, will be promulgated as necessary by 

 the cognizant area or force commander. 



WEATHER SERVICES 



The very large and nearly continuous flow 

 of data required to provide operational fore- 

 casts necessitates the use of high-speed data 

 links and centralized computer processing. 

 FLENUMWEACEN Monterey, "CA, satisfies this 

 requirement, and, in so doing, affords the fore- 

 caster with additional time for analytical thought 

 and for application of scientific methods in the 

 preparation of forecasts. 



CENTRALIZATION CONCEPT 



Hemispheric data are needed on a routine 

 basis for forecasts beyond 36 to 48 hours. 

 It is not feasible for most units to collect 

 and process the volume of data necessary to 

 meet their requirements for service. The 

 FLEWEACENs, within assigned areas of re- 

 sponsibility, provide the smaller units with prod- 

 ucts that have been computer generated by the 

 FLENUMWEACEN. 



Utilization of Common Services 



Environmental support ashore is provided by 

 certain centrals and facilities andbyallNWSEDs. 

 This support is supplemented in some areas by 

 Air Force services and, within the U.S., by 

 services provided by the Federal Aviation Ad- 

 ministration (FAA) and the National Oceanic 

 and Atmospheric Administration (NOAA). 



Common Services Provided 

 by NAVWEASERV Units 



Weather warnings of tropical phenomena (hur- 

 ricanes, typhoons, etc.) are routinely provided 

 to activities ashore by designated FLEWEACENs. 

 Daily forecasts and warnings of extratropical 

 destructive weather (high winds, thunderstorms, 

 etc.) are routinely provided for the local area 

 by the co-located NAVWEASERV activity. 



Local and functional areas of responsibility 

 are assigned and described in the U. S. Navy 

 Meteorological and Oceanographic Support Man- 

 ual, NAVWEASERVCOMINST 3140.1( ).
