Rivadavia, Salta
Rivadavia is a town in eastern Salta Province, Argentina in the Department of Rivadavia, from the city of Salta. It is in a low-lying region of the province. Geography Climate Rivadavia has a hot semi-arid climate (''BSh'') according to the Köppen climate classification, having too little rainfall for a humid subtropical climate. Using the Trewartha climate classification the climate is semi-arid A semi-arid climate, semi-desert climate, or steppe climate is a aridity, dry climate sub-type.

Time In Argentina
Argentina is located at a longitude that would naturally put it in the UTC−04:00 or UTC−05:00 time zone; however, it actually uses the UTC−03:00 time zone. Argentina determines whether to change clocks in observation of daylight saving time on a year-by-year basis, and individual provinces may opt out of the federal decision. At present, Argentina does not change clocks. The Argentine Hydrographic Service maintains the official national time. History The first official standardization of time in Argentina took place on 31 October 1894, with establishment of UTC−04:00 as the nation's standard time Standard time is the synchronization of clocks within a geographical region to a single time standard, rather than a local mean time standard. Generally, standard time agrees with the local mean time at some meridian that passes through the r .... From 1920 to 1969, the official time switched biannually between UTC−04:00 as standard time in winter and UTC−03:0 ... [...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 ...

Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSh'' and ''BSk'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as they usually cannot support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): * ...

Salta Province
Salta () is a Provinces of Argentina, province of Argentina, located in the northwest of the country. Neighboring provinces are from the east clockwise Formosa Province, Formosa, Chaco Province, Chaco, Santiago del Estero Province, Santiago del Estero, Tucumán Province, Tucumán and Catamarca Province, Catamarca.

History Before the Spanish colonization of the Americas, Spanish conquest, numerous native peoples (now called Diaguitas and Calchaquíes) lived in the valleys of what is now Salta Province; they formed many different tribes, the Quilmes (tribe), Quilmes and Humahuacas among them, which all shared the Cacán language. The Atacama people, Atacamas lived in the Altiplano, Puna, and the Wichís (Matacos), in the Gran Chaco, Chaco region. The first conquistadores, conquistador to venture into the area was Diego de Almagro in 1535; he was followed by Diego de Ro ...

Humid Subtropical Climate
A humid subtropical climate is a subtropical -temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia) or oceanic climates (in other continents). It is also known as warm temperate climate in some climate classifications. Under the Köppen climate classification, ''Cfa'' and ''Cwa'' climates are either described as humid subtropical climates or warm temperate climates. This climate features mean temperature in the coldest month between (or ) and and mean temperature in the warmest month or higher. However, while some climatologists have opted to describe this climate type as a "humid subtropical climate", Köppen himself never used this term. The humid subtropical climate classific ...

Trewartha Climate Classification
The Trewartha climate classification (TCC), or the Köppen–Trewartha climate classification (KTC), is a climate classification system first published by American geographer Glenn Thomas Trewartha in 1966. It is a modified version of the Köppen–Geiger system, created to answer some of its deficiencies. The Trewartha system attempts to redefine the middle latitudes to be closer to vegetation zoning and genetic climate systems. Scheme Trewartha's modifications to the 1884 Köppen climate system sought to reclass the middle latitudes into three groups, according to how many months have a mean temperature of or higher: * ''C'' (subtropical)—8 or more months; * ''D'' (temperate)—4 to 7 months; * ''E'' ( boreal climate)—1 to 3 months. The tropical climates and polar climates remained the same as in the original Köppen climate classification. The "highland" climate is ambiguously defined. Newer users of KTC generally omit this option. Group A: Tropical climates This is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Oceanic And Atmospheric Administration
The National Oceanic and Atmospheric Administration (NOAA ) is an American scientific and regulatory agency charged with Weather forecasting, forecasting weather, monitoring oceanic and atmospheric conditions, Hydrography, charting the seas, conducting deep-sea exploration, and managing fishing and protection of marine mammals and endangered species in the US exclusive economic zone. The agency is part of the United States Department of Commerce and is headquartered in Silver Spring, Maryland.

Deutscher Wetterdienst
The () or DWD for short, is the German Meteorological Service, based in Offenbach am Main, Germany, which monitors weather and meteorological conditions over Germany and provides weather services for the general public and for nautical, aviation, hydrometeorological or agricultural purposes. It is attached to the Federal Ministry for Transport. The DWDs principal tasks include warning against weather-related dangers and monitoring and rating climate changes affecting Germany. The organisation runs atmospheric models on their supercomputer for precise weather forecasting. The DWD also manages the national climate archive and one of the largest specialised libraries on weather and climate worldwide. History The DWD was formed on 11 November 1952 when the weather services of the western occupation zones were merged. In 1954, the Federal Republic of Germany joined the World Meteorological Organization (WMO). In 1990, following the reunification, the weather services of t ...
