The 20th Operational Weather Squadron which provided forecasts for the Air Force and Army in Japan and South Korea, is now inactive following the transfer of its mission to Hickam Air Force Base, Hawaii on April 17, 2006.

An army or land force is a fighting force that fights primarily on land. In the broadest sense, it is the land-based military branch, service branch or armed service of a nation or state. It may also include aviation assets by possessing an army aviation component. In certain states, the term army refers to the entire armed forces. Within a national military force, the word army may also mean a field army.

Japan Constitutional monarchy in East Asia

Japan is an island country in East Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asian continent and stretches from the Sea of Okhotsk in the north to the East China Sea and the Philippine Sea in the south.

South Korea Republic in East Asia

South Korea, officially the Republic of Korea (ROK), is a country in East Asia, constituting the southern part of the Korean Peninsula and lying to the east of the Asian mainland. The name Korea is derived from Goguryeo which was one of the great powers in East Asia during its time, ruling most of the Korean Peninsula, Manchuria, parts of the Russian Far East and Inner Mongolia, under Gwanggaeto the Great. South Korea lies in the north temperate zone and has a predominantly mountainous terrain. It comprises an estimated 51.4 million residents distributed over 100,363 km2 (38,750 sq mi). Its capital and largest city is Seoul, with a population of around 10 million.

Mission

Until its inactivation in April 2006, the 20th Operational Weather Squadron was responsible for producing and disseminating mission planning and execution weather analyses, forecasts, and briefings for Air Force, Army, Navy, Marines, Guard, Reserve, USFK, PACOM, PACAF, USAPRAC, SOCPAC, and NAVPAC forces operating at 115 installations/sites over 5.2 million sq.mi. within the Pacific theater of operations.

Navy Military branch of service primarily concerned with naval warfare

A navy or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores. The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications, open-ocean applications, and something in between, although these distinctions are more about strategic scope than tactical or operational division.

This weather squadron was responsible for base or post forecasting, developing weather products, briefing transient aircrews, and weather warnings for all of their geographical units. Using automatic observing systems located at all military installations and communicating with their combat weather flights, the squadron was able to 'watch' the weather in their entire area of responsibility from one central location.

The Operational Weather Squadron was the first place a newly schooled weather apprentice would report. At the squadron, working alongside a seasoned weather professional, the forecaster was trained in all aspects of Air Force meteorology, from pilot briefing to tactical forecasting.

Meteorology Interdisciplinary scientific study of the atmosphere focusing on weather forecasting

Meteorology is a branch of the atmospheric sciences which includes atmospheric chemistry and atmospheric physics, with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not occur until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics and more particularly, the development of the computer, allowing for the automated solution of a great many equations that model the weather, in the latter half of the 20th century that significant breakthroughs in weather forecasting were achieved.

The weather squadron worked closely with the combat weather flights they support to ensure a flawless exchange of weather information.

Cairo City in Egypt

Cairo is the capital of Egypt. The city's metropolitan area is one of the largest in Africa, the largest in the Middle East, and the 15th-largest in the world, and is associated with ancient Egypt, as the famous Giza pyramid complex and the ancient city of Memphis are located in its geographical area. Located near the Nile Delta, modern Cairo was founded in 969 CE by the Fatimid dynasty, but the land composing the present-day city was the site of ancient national capitals whose remnants remain visible in parts of Old Cairo. Cairo has long been a centre of the region's political and cultural life, and is titled "the city of a thousand minarets" for its preponderance of Islamic architecture. Cairo is considered a World City with a "Beta +" classification according to GaWC.

Egypt Country spanning North Africa and Southwest Asia

Egypt, officially the Arab Republic of Egypt, is a country spanning the northeast corner of Africa and southwest corner of Asia by a land bridge formed by the Sinai Peninsula.

Blue and yellow are the Air Force colors. Blue alludes to the sky, the primary theater of operations. Yellow refers to the sun and the excellence required of Air Force personnel. The weather satellite symbolizes the mission of the unit to provide support in the atmospheric sciences. The black and light blue background depicts night and day capability. The globe is from the emblem of the parent major command and further depicts global responsibilities. The two stars indicate the services, US Air Force and U.S. Army, that the unit supports by providing meteorological information.

Weather Short-term state of the atmosphere

Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Most weather phenomena occur in the lowest level of the atmosphere, the troposphere, just below the stratosphere. Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth.

History

The 20th Weather Squadron activated at Cairo, Egypt, on April 15, 1943, and was assigned to the Ninth Air Force, but was soon thereafter disbanded on October 31, 1943.

The Army Air Forces again activated the 20th on December 6, 1944, on Biak Island in what was then known as the Netherlands East Indies, today’s Indonesia. The 20th absorbed the resources and mission of the 5231st Weather Squadron (Provisional). The 20th was assigned to the Far East Air Forces Weather Group (Provisional) at that time.

In May 1945 the squadron moved its headquarters by from Biak Island to Fort William McKinley near Manila, Philippines. By the close of July 1945, the squadron had grown to more than 700 men and the headquarters was overseeing the work of 34 weather stations, many of which were in isolated locations.

The Army Air Forces Weather Service assumed control of all weather organizations on July 1, 1945, and organized the 20th under the 1st Weather Group on September 20, 1945. Due to congested quarters at Fort William McKinley, the 20th’s headquarters moved again in August 1945 to nearby Nichols Field. While headquartered in the Philippines, the 20th lost two men to combat action.

Following the capitulation of Japan, the 20th began its long association with Japan. The squadron moved its headquarters to Tokyo on November 2, 1945, and accompanied Headquarters, Fifth Air Force to Nagoya on May 22, 1946.

War demobilization caused the 20th to lose personnel rapidly. To accomplish its growing mission, the 20th hired local nationals, employed non-weather officers to oversee some weather stations, and began on the-job schools to cross-train enlisted men into weather career fields.

By late 1946, the 20th was operating weather stations in Japan, China, and Korea. The 20th relinquished control of the China stations in 1947 and the last Korean station was closed in 1949. The squadron came under the leadership of the 2143d Air Weather Wing in 1949.

Within three days of North Korean troops crossing into South Korea in June 1950, a detachment of the 20th Weather Squadron was airlifted to Daegu, Korea. The leadership of the 20th Weather Squadron was soon burdened by the growth of detachments both in Korea and Japan to support the war effort. By early November 1950, the 20th was overseeing 27 detachments, eight of which were in Korea, where, on average, one of these detachments relocated every five days. The Air Force activated the 30th Weather Squadron to oversee Korean operations, but the 20th remained deeply involved in the war effort.

The 20th was assigned to the newly activated 1st Weather Wing in 1954. The squadron was inactivated on February 18, 1957, but emerged anew at Fuchu Air Station, Japan, on June 8, 1964, where it remained until 1974 when it relocated to Yokota Air Base. Again, it was inactivated in 1976 as part of an Air Weather Service reorganization only to return at Yokota on January 1, 1985.

As part of the divestiture of Air Weather Service, the 20th was assigned to Pacific Air Forces in 1991. It relocated to Hickam Air Force Base, Hawaii, on April 1, 1992, and was inactivated on June 1. With the reengineering of the Air Force Weather Agency the 20th was redesignated an Operational Weather Squadron on July 13, 2000, and activated on October 1. It was assigned to Fifth Air Force and stationed again at Yokota Air Base, Japan.

Recent history

The 20th Operational Weather Squadron became inactive on April 17, 2006 when its mission was transferred to the 17th Operational Weather Squadron at Hickam Field, Hawaii.
