Korea Meteorological Administration
The Korea Meteorological Administration (KMA; ) is the national meteorological service of South Korea. The service started in 1904 joining the WMO in 1956. Numerical weather prediction is performed using the Unified Model software suite. History The current administration was established in 1990. Temporary observatories set up in 1904 in Busan, Incheon, Mokpo and elsewhere were precursors to the current KMA. The Central Meteorological Office (CMO) was established in August 1949. In April 1978, CMO was renamed the Korea Meteorological Service (KMS). In 1999, the administration introduced a meteorological supercomputer for forecasting. As of November 2021, supercomputers ''Guru'' and ''Maru'' ranked 27th and 28th respectively TOP500, in the world. In 2010, the KMA launched South Korea’s first geostationary meteorological satellite, the Communication, Ocean and Meteorological Satellite (COMS), also known as Chollian. Chollian started its official operation in 2011. The Seoul and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

S-band
The S band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a part of the microwave band of the electromagnetic spectrum covering frequencies from 2 to 4 gigahertz (GHz). Thus it crosses the conventional boundary between the UHF and SHF bands at 3.0 GHz. The S band is used by airport surveillance radar for air traffic control, weather radar, surface ship radar, and some communications satellites, particularly satellites used by NASA to communicate with the Space Shuttle and the International Space Station. The 10 cm radar short-band ranges roughly from 1.55 to 5.2 GHz. India's regional satellite navigation network ( IRNSS) broadcasts on 2.483778 to 2.500278 GHz. The S band also contains the 2.4–2.483 GHz ISM band, widely used for low power unlicensed microwave devices such as cordless phones, wireless headphones (Bluetooth), garage door openers, keyless vehicle locks, baby monitors as well as for medic ...

Governmental Meteorological Agencies In Asia
A government is the system or group of people governing an organized community, generally a state. In the case of its broad associative definition, government normally consists of legislature, executive, and judiciary. Government is a means by which organizational policies are enforced, as well as a mechanism for determining policy. In many countries, the government has a kind of constitution, a statement of its governing principles and philosophy. While all types of organizations have governance, the term ''government'' is often used more specifically to refer to the approximately 200 independent national governments and subsidiary organizations. The main types of modern political systems recognized are democracies, totalitarian regimes, and, sitting between these two, authoritarian regimes with a variety of hybrid regimes. Modern classification systems also include monarchies as a standalone entity or as a hybrid system of the main three. Historically prevalent forms ...

State Hydro-Meteorological Administration
The State Hydro-Meteorological Administration ( Chosongul: ) is the National Meteorological service of the Democratic People's Republic of Korea. The service started in 1961, joining the WMO in 1975. History Immediately after liberation, on July 10, 1946, it was founded as the Central Meteorological Organization, an organization under the Ministry of Agriculture and Forestry of the North Korean Provisional People's Committee. In September 1952, it was directly under the cabinet. It was transformed into a State Hydro-Meteorological Administration in March 1961. In May 1975, it became an official member of the World Meteorological Organization (WMO), joined the Intergovernmental Oceanography Committee in November 1978, the International Hydrology Program (IHP) in 1980, and the Antarctic Treaty in November 1987. It became an independent agency in 1995. On 26 August 2020, Korean Central Television (KCTV) broadcast through the night, for the first time, to monitor the progress of Ty ...

Weather Station
A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmosphere of Earth, atmospheric conditions to provide information for weather forecasting, weather forecasts and to study the weather and climate. The measurements taken include temperature, atmospheric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken with as few other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once daily, while automated measurements are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature (SST), wave height, and wave period. Drifting weather buoys outnumber their moored versions by a significant amount. Weather instruments A weather instrument is any device t ...

Weather Radar
A weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation (meteorology), precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the precipitation. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather. During Radar in World War II, World War II, radar operators discovered that weather was causing echoes on their screens, masking potential enemy targets. Techniques were developed to filter them, but scientists began to study the phenomenon. Soon after the war, military surplus, surplus radars were used to detect precipitation. Since then, weather radar has evolved and is used by national weather services, research departments in universities, and in television stations' weather d ...

Klystron
A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian,Pond, Norman H. "The Tube Guys". Russ Cochran, 2008 p.31-40 which is used as an amplifier for high radio frequencies, from ultra high frequency, UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power klystrons are used as output tubes in UHF television transmitters, satellite communication, radar transmitters, and to generate the drive power for modern particle accelerators. In a klystron, an electron beam interacts with radio waves as it passes through cavity resonator, resonant cavities, metal boxes along the length of a tube. The electron beam first passes through a cavity to which the input signal is applied. The energy of the electron beam amplifies the signal, and the amplified signal is taken from a cavity at the other end of the tube. The output signal ...
