Geography Of Mali
Mali is a landlocked nation in West Africa, located southwest of Algeria, extending south-west from the southern Sahara Desert through the Sahel to the Sudanian savanna zone. Mali's size is 1,240,192 square kilometers. Desert or semi-desert covers about 65 percent of Mali's total area (1,240,192 square kilometers). The Niger River creates a large and fertile inland delta as it arcs northeast through Mali from Guinea before turning south and eventually emptying into the Gulf of Guinea. The territory encompasses three natural zones: the southern cultivated Sudanese zone, central semi-desert Sahelian zone, and northern desert Saharan zone. The terrain is primarily savanna in the south and flat to rolling plains or high plateau (200–500 meters in elevation) in the north. There are rugged hills in the northeast, with elevations of up to 1,000 meters. The Niger (with 1,693 kilometers in Mali) and Senegal are Mali's two largest rivers. The Niger is generally described as Mali's l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Wet And Dry Climate
Tropical savanna climate or tropical wet and dry climate is a tropical climate sub-type that corresponds to the Köppen climate classification categories ''Aw'' (for a dry winter) and ''As'' (for a dry summer). The driest month has less than of precipitation and also less than 100-\left (\frac \right)mm of precipitation. This latter fact is in a direct contrast to a tropical monsoon climate, whose driest month sees less than of precipitation but has ''more'' than 100-\left (\frac \right) of precipitation. In essence, a tropical savanna climate tends to either see less overall rainfall than a tropical monsoon climate or have more pronounced dry season(s). In tropical savanna climates, the dry season can become severe, and often drought conditions prevail during the course of the year. Tropical savanna climates often feature tree-studded grasslands due to its dryness, rather than thick jungle. It is this widespread occurrence of tall, coarse grass (called savanna) which has led to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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, aviational, hydrometeorological or agricultural purposes. It is attached to the Federal Ministry for Digital and 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 in 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World Meteorological Organization
The World Meteorological Organization (WMO) is a specialized agency of the United Nations responsible for promoting international cooperation on atmospheric science, climatology, hydrology and geophysics. The WMO originated from the International Meteorological Organization, a nongovernmental organization founded in 1873 as a forum for exchanging weather data and research. Proposals to reform the status and structure of the IMO culminated in the World Meteorological Convention of 1947, which formally established the World Meteorological Organization. The Convention entered into force on 23 March 1950, and the following year the WMO began operations as an intergovernmental organization within the UN system. The WMO is made up of 193 countries and territories, and facilitates the "free and unrestricted" exchange of data, information, and research between the respective meteorological and hydrological institutions of its members. It also collaborates with nongovernmental partners ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subtropical Ridge
The horse latitudes are the latitudes about 30 degrees north and south of the Equator. They are characterized by sunny skies, calm winds, and very little precipitation. They are also known as Subtropics, subtropical ridges, or highs. It is a high-pressure area at the divergence of trade winds and the westerlies. Origin of the term A likely and documented explanation is that the term is derived from the "dead horse" ritual of seamen (see Flogging a dead horse#Earlier meaning, Beating a dead horse). In this practice, the seaman paraded a straw-stuffed effigy of a horse around the deck before throwing it overboard. Seamen were paid partly in advance before a long voyage, and they frequently spent their pay all at once, resulting in a period of time without income. If they got advances from the ship's paymaster, they would incur debt. This period was called the "dead horse" time, and it usually lasted a month or two. The seaman's ceremony was to celebrate having worked off the "d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunshine Duration
Sunshine duration or sunshine hours is a climatological indicator, measuring duration of sunshine in given period (usually, a day or a year) for a given location on Earth, typically expressed as an averaged value over several years. It is a general indicator of cloudiness of a location, and thus differs from insolation, which measures the total energy delivered by sunlight over a given period. Sunshine duration is usually expressed in hours per year, or in (average) hours per day. The first measure indicates the general sunniness of a location compared with other places, while the latter allows for comparison of sunshine in various seasons in the same location. Another often-used measure is percentage ratio of recorded bright sunshine duration and daylight duration in the observed period. An important use of sunshine duration data is to characterize the climate of sites, especially of health resorts. This also takes into account the psychological effect of strong solar light on ...

Araouane
Araouane or Arawan is a small village in the Malian part of the Sahara Desert, lying north of Timbuktu on the caravan route to the salt-mining centre of Taoudenni. The village once served as an entrepôt in the trans-Saharan trade. History Between the 16th and 19th centuries Araouane acted as an entrepôt in the important trans-Sahara trade. The French explorer, René Caillié passed through Araouane in 1828 on his journey from Timbuktu across the Sahara Desert to Morocco. He travelled in May, the hottest month of the year when the average maximum temperature in Timbuktu soars to 43–44 °C. He left Timbuktu with a caravan of 600 camels transporting gold, slaves, ivory, gum arabic, ostrich-feathers and cloth. The caravan mostly travelled at night and took six days to reach Araouane where it stopped for nine days before setting out again towards Taoudenni with an additional 800 camels. Caillié gives this description of Araouane: El-Arawan like Timbuctoo possesses no resourc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
