State Meteorological Agency
The State Meteorological Agency (, AEMET) is a state agency of the Government of Spain responsible for providing weather forecast, warnings of hazardous weather and assisting the administrations in such matters. The AEMET is part of the Secretariat of State for Environment of the Ministry for the Ecological Transition and is headquartered in the University City, Madrid. The agency was known as Central Institute of Meteorology from 1887 to 1978 and National Institute of Meteorology from 1978 to 2008 when it adopted its current name. The AEMET performs its task through a collection of data from its network of centers. The agency has centers distributed through the regions and it has offices in almost every airport and air force base. In addition, there are synoptic observatories spread throughout the Spanish geography. It represents Spain in international meteorological institutions, such as the World Meteorological Organization (WMO), the European Organisation for the Exploitation ...

Institución Libre De Enseñanza
La Institución Libre de Enseñanza (ILE, English: ''The Free Institution of Education''), was an educational project developed in Spain for over half a century (1876–1936). The institute was inspired by the philosophy of Krausism, first introduced to the Complutense University of Madrid by Julián Sanz del Río, and which, despite being subsequently ejected from that university, was to have a significant impact on intellectual life in Restoration Spain. The institution was founded in 1876 by a group of disaffected university professors, including Francisco Giner de los Ríos, Gumersindo Azcarate, Teodoro Sainz Rueda and Nicolás Salmerón, who distanced themselves from the main university campus in Madrid to achieve academic freedom. They declined to adjust their teaching to any official religious dogma or the moral and political imposition of the time. Consequently, they had to continue their educational work outside the state sector by creating a secular private educational ...

Governmental Meteorological Agencies In Europe
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 major types of political systems in the modern era are democracies, monarchies, and authoritarian and totalitarian regimes. Historically prevalent forms of government include monarchy, aristocracy, timocracy, oligarchy, democracy, theocracy, and tyranny. These forms are not always mutually exclusive, and mixed governme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lightning Detection
A lightning detector is a device that detects lightning produced by thunderstorms. There are three primary types of detectors: ''ground-based'' systems using multiple antennas, ''mobile systems'' using a direction and a sense antenna in the same location (often aboard an aircraft), and ''space-based systems''. The first such device was invented in 1894 by Alexander Stepanovich Popov. It also was the first radio receiver in the world. Ground-based and mobile detectors calculate the direction and severity of lightning from the current location using radio direction-finding techniques along with an analysis of the characteristic frequencies emitted by lightning. Ground-based systems use triangulation from multiple locations to determine distance, while mobile systems estimate distance using signal frequency and attenuation. Space-based detectors on satellites can be used to locate lightning range, bearing and intensity by direct observation. Ground-based lightning detector networ ...

Weather Radar
Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate 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 World War II, radar operators discovered that weather was causing echoes on their screen, masking potential enemy targets. Techniques were developed to filter them, but scientists began to study the phenomenon. Soon after the war, surplus radars were used to detect precipitation. Since then, weather radar has evolved on its own and is now used by national weather services, research departments in universities, and in television stations' weather departments. Raw images are routinely used and speciali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiosonde
A radiosonde is a battery-powered telemetry instrument carried into the atmosphere usually by a weather balloon that measures various atmospheric parameters and transmits them by radio to a ground receiver. Modern radiosondes measure or calculate the following variables: altitude, pressure, temperature, relative humidity, wind (both wind speed and wind direction), cosmic ray readings at high altitude and geographical position (latitude/longitude). Radiosondes measuring ozone concentration are known as ozonesondes. Radiosondes may operate at a radio frequency of 403 MHz or 1680 MHz. A radiosonde whose position is tracked as it ascends to give wind speed and direction information is called a rawinsonde ("radar wind -sonde"). Most radiosondes have radar reflectors and are technically rawinsondes. A radiosonde that is dropped from an airplane and falls, rather than being carried by a balloon is called a dropsonde. Radiosondes are an essential source of meteorological data ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weather Station
A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for 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 Typical weather stations have the following instruments: * Thermometer for ...

Numerical Weather Prediction
Numerical weather prediction (NWP) uses mathematical models of the atmosphere and oceans to predict the weather based on current weather conditions. Though first attempted in the 1920s, it was not until the advent of computer simulation in the 1950s that numerical weather predictions produced realistic results. A number of global and regional forecast models are run in different countries worldwide, using current weather observations relayed from radiosondes, weather satellites and other observing systems as inputs. Mathematical models based on the same physical principles can be used to generate either short-term weather forecasts or longer-term climate predictions; the latter are widely applied for understanding and projecting climate change. The improvements made to regional models have allowed for significant improvements in tropical cyclone track and air quality forecasts; however, atmospheric models perform poorly at handling processes that occur in a relatively const ...

Weather Forecasting
Weather forecasting is the application of science and technology forecasting, to predict the conditions of the Earth's atmosphere, atmosphere for a given location and time. People have attempted to predict the weather informally for millennia and formally since the 19th century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere, land, and ocean and using meteorology to project how the atmosphere will change at a given place. Once calculated manually based mainly upon changes in atmospheric pressure, barometric pressure, current weather conditions, and sky condition or cloud cover, weather forecasting now relies on numerical weather prediction, computer-based models that take many atmospheric factors into account. Human input is still required to pick the best possible forecast model to base the forecast upon, which involves pattern recognition skills, teleconnections, knowledge of model performance, and knowledge of model biases ...

Sovereign State
A sovereign state or sovereign country, is a polity, political entity represented by one central government that has supreme legitimate authority over territory. International law defines sovereign states as having a permanent population, defined territory (see territorial disputes), one government, and the capacity to enter into International relations, relations with other sovereign states. It is also normally understood that a Sovereignty#Sovereignty and independence, sovereign state is independent. According to the declarative theory of statehood, a sovereign state can exist without being Diplomatic recognition, recognised by other sovereign states.Thomas D. Grant, ''The recognition of states: law and practice in debate and evolution'' (Westport, Connecticut: Praeger, 1999), chapter 1. List of states with limited recognition, Unrecognised states will often find it difficult to exercise full treaty-making powers or engage in Diplomacy, diplomatic relations with other sovereign ...

Ministry Of Transport (Spain)
The Ministry of Transport was a department of the Government of Spain which existed between 1977 and 1991. The Department was originally named Ministry of Transport and Communications and it was endowed with powers over the postal, telegraphic, radiotelegraphic, telephone and radiotelephone services, the management of all kind of transports (land, air and maritime) and fishery. The fishery powers were transferred to the Ministry of Agriculture in 1980 and the same year the Secretariat of State for Tourism was added to the Ministry. For this reason, the department was renamed Ministry of Transport, Tourism and Communications the following year until its dissolution in 1991. The Department of Transport was suppressed in March 1991 and most of its competences returned to the Ministry of Public Works. From 1977 to 1991, seven people served as Ministers of Transport.

Spanish Civil War
The Spanish Civil War ( es, Guerra Civil Española)) or The Revolution ( es, La Revolución, link=no) among Nationalists, the Fourth Carlist War ( es, Cuarta Guerra Carlista, link=no) among Carlists, and The Rebellion ( es, La Rebelión, link=no) or The Uprising ( es, La Sublevación, link=no) among Republicans. was a civil war in Spain fought from 1936 to 1939 between the Republicans and the Nationalists. Republicans were loyal to the left-leaning Popular Front government of the Second Spanish Republic, and consisted of various socialist, communist, separatist, anarchist, and republican parties, some of which had opposed the government in the pre-war period. The opposing Nationalists were an alliance of Falangists, monarchists, conservatives, and traditionalists led by a military junta among whom General Francisco Franco quickly achieved a preponderant role. Due to the international political climate at the time, the war had many facets and was variously viewed as cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
