607th Weather Squadron The 607th Weather Squadron ( 607 WS ) of the U . S . Air Force has overall responsibility for planning , providing , and / or arranging weather support for the United States Army during armistice conditions in Korea . 607 WS and elements of the US Navy and US Marines support the Republic of Korea Air Force ( ROKAF ) Weather Wing , Combined Meteorological and Oceanographic ( METOC ) Officer ( CMO ) and subordinate squadrons during exercises and contingencies . The 607 WS commander is also the Joint METOC Officer ( JMO ) and the senior US METOC officer ( SMO ) for the Korean Theater of Operations ( KTO ) . History . Following the conclusion of World War II , Korean weather support was managed by the 20th Weather Squadron , headquartered in Japan . The lone Air Force weather detachment in Korea was closed in September 1949 . Mobile units of the 20th returned to Korea the next year at the start of the Korean War . The 30th Weather Squadron was soon reactivated with its headquarters in Korea to support the Fifth Air Force and other United Nations Forces . Within one month , the unit ' s headquarters were forced to retreat south from Seoul to Taegu . It remained in Taegu until July 1951 , when it returned to Seoul . In 1954 , the headquarters moved to Osan Air Base . After the end of the Korean War , the 30th Weather Squadron began to turn over several of its locations to the Republic of Korea ( ROK ) Air Force . In 1957 , headquarters of the 30th moved from Korea to Japan , to oversee the weather detachments in Korea and Japan with the inactivation of the 20th Weather Squadron . In 1957 , the 30th was assigned to the 10th Weather Group . In 1959 , the 30th was inactivated and its detachments assigned directly to the 10th Weather Group . The 10th Weather Group was inactivated in 1960 . From 1960 to 1964 , the remaining USAF weather units in Korea reported directly to the First Weather Wing located at Hickam AFB , Hawaii . In 1964 , the 20th Weather Squadron was reactivated at Fuchu Air Station , Japan , and again took responsibility for managing the USAF weather units in Korea . In 1974 , 20th Weather Squadron headquarters moved to Yokota AB , Japan , and continued to manage USAF weather support in Korea until it was inactivated on 1 September 1976 . On that date , the 30th Weather Squadron was reactivated at Yongsan Army Garrison , Seoul , and all USAF weather units on the Korean peninsula were placed under the squadron ' s control . The 30th Weather Squadron managed all US weather support in Korea until 1992 . In 1992 , the US Air Force reorganized , placing all support assets under the control of the local Wing Commander . The 30th Weather Squadron was again inactivated , the squadron at Yongsan was redesignated as the 51st Weather Squadron , and weather units at Osan and Kunsan were removed from squadron control and placed under the local USAF Wing Commanders at their respective bases . The 51st Weather Squadron continued to manage weather support to the Commander , United Nations Command , the Commander , Combined Forces Command , the Commander , United States Forces Korea ( CDR , USFK ) , the Commander , Eighth Army ( CDR , 8A ) , and to all US Army units on the peninsula . Because the 51st Weather Squadron was not under the operational control of the 51st Fighter Wing at Osan AB , the decision was made in July 1993 to replace it with the reactivated 5th Weather Squadron , which had a long lineage of battle decorations from the Pacific Theater in World War II and the Vietnam War . Another USAF restructuring of Numbered Air Forces and a drive toward standardized naming conventions caused the Air Force to inactivate the 5th Weather Squadron and to activate the 607th Weather Squadron in December 1994 . Today , the 607th Weather Squadron is part of the 607th Air Support Operations Group , 7th Air Force , Pacific Air Forces . In 1999 , the 607th Weather Squadron became the USAF ' s second " Weather Hub " . In this capacity , the squadron was responsible for providing all point and area weather forecasts for US Forces Command forces operating on the Korean Peninsula . The Weather Hub portion of the 607th was decommissioned and moved to Japan in 2003 . Today , the 607th Weather Squadron has 62 personnel assigned at four locations throughout the Republic of Korea including USAG - Yongsan , Seoul ; K - 16 Air Base , Seoul AB East ; USAG - Red Cloud , Uijongbu ; and USAG - Humphreys , Pyongtaek . Organization . The 607 WS is functionally organized to provide weather support to Headquarters , United Nations Command / US Forces Korea ( UNC / USFK ) and subordinate Air , Ground , Naval , Marine and Special Operations Component Commands . In - theater units provide weather support at 15 locations in the ROK . Five locations support the U . S . Army ' s 2 Combat Aviation Brigade and 2nd Infantry Division ( United States ) and three units support combined / joint operations during exercises and contingencies . These units would be augmented by weather forces attached to and supporting inbound combat units in contingencies / war . The 607 WS at ( United States Army Garrison ) USAG - Yongsan , Seoul is divided into two main functional areas : staff support , and the weather team for Seoul AB East at K - 16 . The 607 WS provides weather forecast products for Korea and the adjacent waters . The staff form the nucleus of the Combined Meteorological Forecast Unit ( CMFU ) during exercises / contingencies . Forecasters assigned to the staff also prepare weather forecasts for American Forces Korean Network ( AFKN ) . USAG Humphreys is the regional briefing station for the Korean Theater of Operations . The 607WS staff areas of expertise include operations , forecasting , observing , plans , communications , mobility / readiness , security , scientific services , administration , training and logistics . The 607 WS staff provides direct support to the UNC / USFK and Eighth Army ( 8A ) . They maintain liaison with US Navy weather support activities and also coordinate weather support with the ROKAF Weather Wing ( WW ) of the ROK Air Force and ROK Navy . The combat weather teams provide briefings , observations , and staff weather support , including limited observing support at H - 264 helipad .
