Campidano
Campidano () is a plain located in South-Western Sardinia (Italy), covering approximately 100 kilometres between Cagliari and Oristano. Geography Geologically, it is a graben, a tectonic structure formed in the mid-Pliocene/early Pleistocene (4 to 2 million years ago). Later it was subject to large sedimentary deposition phenomena, creating an overall thickness of 600 m of sediments. The plain is crossed by the Tirso River, the longest in Sardinia. History Agriculture has been successful in Campidano since the Neolithic, continuing on through the Punic and the Romans, who cultivated here grains and grape. Dams of the large Sardinian rivers nourish the artichoke and wheat cultures, also typical products of this zone. Paddy fields are present near Oristano. The Sardinians from this area, and by extension all the people inhabiting the lowlands of Southern Sardinia, are called Campidanese (, ).

National Institute Of Statistics (Italy)
The Italian National Institute of Statistics (; Istat) is the primary source of official statistics in Italy. The institute conducts a variety of activities, including the census of population, economic censuses, and numerous social, economic, and environmental surveys and analyses. Istat is the largest producer of statistical information in Italy and is actively involved in the European Statistical System, which is overseen by Eurostat. History The Italian National Institute of Statistics () was established by Legislative decree no. 1162 on 9 July, 1926, as the Central Institute of Statistics () in order to replace the General Statistics Division of the Ministry of Agriculture, Food Sovereignty and Forests (Italy), Ministry of Agriculture. Corrado Gini was established as the first director of the institute, under the authority of the head of state. The institute, with a staff of about 170 workers, was charged with publishing the data of the 6th general population census, gener ...

Servizio Meteorologico
The Italian Meteorological Service () is an organizational unit of the Italian Air Force and the national meteorological service in Italy. The weather forecasts and other services serve both the armed forces and the general public. Organization Unlike almost all other national meteorological services, its historical development in Italy has led to it being within the armed forces. On the one hand this avoids duplication between government civilian and military weather services. On the other military priorities entail disadvantages in comparison to purely civilian organizations, especially in the field of international cooperation. The Italian Air Force Weather Service reports to a department at the General Staff of the Air Force in Rome. They are also responsible for planning and policy matters to promote international cooperation through the World Meteorological Organization. The headquarters of the Meteorological Service is located on the Pratica di Mare Air Base near Rome. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...

Humidity
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation (meteorology), precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 8 g of water per cubic metre of air at , and 28 g of water per cubic metre of air at Three primary measurements of humidity are widely employed: abso ...

Sirocco
Sirocco ( ) or scirocco is a Mediterranean wind that comes from the Sahara and can reach hurricane speeds in North Africa and Southern Europe, especially during the summer season. Names ''Sirocco'' derives from '' šurūq'' (), verbal noun of '' šaraqa'', related to the East, ''aš-šarq''. Various names for this wind in other languages include: * * * or ''marin'' * * * * or * * , or romanized: sirókos * or * ( sr-Cyrl, југо), in Croatia rarely ''širok'' (широк) * * or * Libyan Arabic: , romanized: , which means "coming from the Qibla" * , which means "fifty" ("fifty-day wind") * , probably from with the same meaning as ; or * , pronounced širguī The Roman poet Horace refers to the sirocco at Trevico in Apulia as "Atabulus" (a Messapic word) in his account of his journey to Brundisium in 37 BC. Development Siroccos arise from warm, dry, tropical air masses that are pulled northward by low-pressure cells moving eastward across the Med ...

Mistral (wind)
The mistral (; ; Corsican: ''maestrale''; ; ; ; ) is a strong, cold, northwesterly wind that blows from southern France into the Gulf of Lion in the northern Mediterranean. It produces sustained winds averaging 31 miles an hour (50 kilometres an hour), sometimes reaching 60 miles an hour (100 kilometres an hour). It can last for several days. Periods of the wind exceeding for more than sixty-five hours have been reported. It is most common in the winter and spring, and strongest in the transition between the two seasons. It affects the northeast of the plain of Languedoc and Provence to the east of Toulon, where it is felt as a strong west wind. It has a major influence all along the Mediterranean coast of France, and often causes sudden storms in the Mediterranean between Corsica and the Balearic Islands. The name ''mistral'' comes from the Languedoc dialect of the Occitan and means "masterly". The same wind is called ''mistrau'' in the Provençal variant of Occitan, ''me ...

Anticyclone
A high-pressure area, high, or anticyclone, is an area near the surface of a planet where the atmospheric pressure is greater than the pressure in the surrounding regions. Highs are middle-scale meteorological features that result from interplays between the relatively larger-scale dynamics of an entire planet's atmospheric circulation. The strongest high-pressure areas result from masses of cold air which spread out from polar regions into cool neighboring regions. These highs weaken once they extend out over warmer bodies of water. Weaker—but more frequently occurring—are high-pressure areas caused by atmospheric subsidence: Air becomes cool enough to precipitate out its water vapor, and large masses of cooler, drier air descend from above. Within high-pressure areas, winds flow from where the pressure is highest, at the center of the area, towards the periphery where the pressure is lower. However, the direction is not straight from the center outwards, but curved du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Climate
A Mediterranean climate ( ), also called a dry summer climate, described by Köppen and Trewartha as ''Cs'', is a temperate climate type that occurs in the lower mid-latitudes (normally 30 to 44 north and south latitude). Such climates typically have dry summers and wet winters, with summer conditions being hot and winter conditions typically being mild. These weather conditions are typically experienced in the majority of Mediterranean-climate regions and countries, but remain highly dependent on proximity to the ocean, altitude and geographical location. The dry summer climate is found throughout the warmer middle latitudes, affecting almost exclusively the western portions of continents in relative proximity to the coast. The climate type's name is in reference to the coastal regions of the Mediterranean Sea, which mostly share this type of climate, but it can also be found in the Atlantic portions of Iberia and Northwest Africa, the Pacific portions of the United States ...

Carboniferous
The Carboniferous ( ) is a Geologic time scale, geologic period and System (stratigraphy), system of the Paleozoic era (geology), era that spans 60 million years, from the end of the Devonian Period Ma (million years ago) to the beginning of the Permian Period, Ma. It is the fifth and penultimate period of the Paleozoic era and the fifth period of the Phanerozoic eon (geology), eon. In North America, the Carboniferous is often treated as two separate geological periods, the earlier Mississippian (geology), Mississippian and the later Pennsylvanian (geology), Pennsylvanian. The name ''Carboniferous'' means "coal-bearing", from the Latin ("coal") and ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern "system" names, it was coined by geologists William Conybeare (geologist), William Conybeare and William Phillips (geologist), William Phillips in 1822, based on a study of the British rock succession. Carboniferous is the per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
