Airolaf
Airolaf ( ar, إيرولاف) is a town in the Tadjoura Region in northwestern Djibouti and in the centre of the Tadjoura Region. It is located some 115 kilometres northwest of the national capital, Djibouti City. Airolaf is known for its temperate, cool climate – the coolest area in Djibouti. The town is overlooked by Goda Mountains, the third tallest mountain in Djibouti. One of the distinctive features of Airolaf countryside is the widespread growing of vegetables. Demographics The majority of the population of Airolaf is Afars. Geography and climate Airolaf has a Steppe climate (BSh) in Köppen-Geiger system. It sits on middle trending highlands known as the Goda Mountains. In the winter months it is quite cold at night, and there can even be frost. However, it rapidly warms up as the tropical sun climbs higher during the day. The temperate central portion, where Airolaf lies, is situated on a rocky plateau. The Goda Mountains have a mixture of highland climate zones ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Djibouti
Djibouti, ar, جيبوتي ', french: link=no, Djibouti, so, Jabuuti officially the Republic of Djibouti, is a country in the Horn of Africa, bordered by Somalia to the south, Ethiopia to the southwest, Eritrea in the north, and the Red Sea and the Gulf of Aden to the east. The country has an area of . In antiquity, the territory, together with Ethiopia, Eritrea and Somaliland, was part of the Land of Punt. Nearby Zeila, now in Somaliland, was the seat of the medieval Adal and Ifat Sultanates. In the late 19th century, the colony of French Somaliland was established following treaties signed by the ruling Dir Somali sultans with the French, and its railroad to Dire Dawa (and later Addis Ababa) allowed it to quickly supersede Zeila as the port for southern Ethiopia and the Ogaden. It was renamed the French Territory of the Afars and the Issas in 1967. A decade later, the Djiboutian people voted for independence. This officially marked the establishment of the ''Rep ...

Day Forest National Park
Day Forest National Park, also known as Forêt du Day National Park, is a national park in the Goda Mountains and Tadjourah Region of Djibouti. Flora Along with Mount Mabla, the Forêt du Day National Park is one of Djibouti's two remnant areas of closed−protected forests. It protects an important forest island in a sea of semi-desert. It has four dominant tree species: '' Juniperus procera'', ''Olea africana'', ''Buxus hildebrandtii'', and '' Tarchonanthus camphoratus''. Doum Palms are found in the western part of the plain of Hanle, at the foot of Gamarré on the edge of the plain of Gagadé. The vegetation becomes more abundant with altitude. Thus the set of Day and its extension to the crest of Goda are occupied by an ancient juniper forest, ficus, mimosa, wild olive trees, boxwood, dragon trees, and other native plants. This is the largest forest in Djibouti. The forest has a total area of approximately 14500 acres. The most valuable part of national park is 2223 acres l ...

Winter
Winter is the coldest season of the year in polar and temperate climates. It occurs after autumn and before spring. The tilt of Earth's axis causes seasons; winter occurs when a hemisphere is oriented away from the Sun. Different cultures define different dates as the start of winter, and some use a definition based on weather. When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere, and vice versa. In many regions, winter brings snow and freezing temperatures. The moment of winter solstice is when the Sun's elevation with respect to the North or South Pole is at its most negative value; that is, the Sun is at its farthest below the horizon as measured from the pole. The day on which this occurs has the shortest day and the longest night, with day length increasing and night length decreasing as the season progresses after the solstice. The earliest sunset and latest sunrise dates outside the polar regions differ from the date of the winte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevation
The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum). The term ''elevation'' is mainly used when referring to points on the Earth's surface, while ''altitude'' or ''geopotential height'' is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and '' depth'' is used for points below the surface. Elevation is not to be confused with the distance from the center of the Earth. Due to the equatorial bulge, the summits of Mount Everest and Chimborazo have, respectively, the largest elevation and the largest geocentric distance. Aviation In aviation the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highland Climate
Alpine climate is the typical weather ( climate) for elevations above the tree line, where trees fail to grow due to cold. This climate is also referred to as a mountain climate or highland climate. Definition There are multiple definitions of alpine climate. In the Köppen climate classification, the alpine and mountain climates are part of group ''E'', along with the polar climate, where no month has a mean temperature higher than . According to the Holdridge life zone system, there are two mountain climates which prevent tree growth : a) the alpine climate, which occurs when the mean biotemperature of a location is between . The alpine climate in Holdridge system is roughly equivalent to the warmest tundra climates (ET) in the Köppen system. b) the alvar climate, the coldest mountain climate since the biotemperature is between 0 °C and 1.5 °C (biotemperature can never be below 0 °C). It corresponds more or less to the coldest tundra climates and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plateau
In geology and physical geography, a plateau (; ; : plateaus or plateaux), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wider ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, plate tectonics movements, and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. The Columbia Plateau in the north-western United States is an example. They may be formed by upwelling of vol ...

Tropical
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. , the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frost
Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change from water vapor (a gas) to ice (a solid) as the water vapor reaches the freezing point. In temperate climates, it most commonly appears on surfaces near the ground as fragile white crystals; in cold climates, it occurs in a greater variety of forms. The propagation of crystal formation occurs by the process of nucleation. The ice crystals of frost form as the result of fractal process development. The depth of frost crystals varies depending on the amount of time they have been accumulating, and the concentration of the water vapor (humidity). Frost crystals may be invisible (black), clear (translucent), or white; if a mass of frost crystals scatters light in all directions, the coating of frost appears white. Types of frost include crystalline frost (hoar fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afar People
The Afar ( aa, Qafár), also known as the Danakil, Adali and Odali, are a Cushitic-speaking ethnic group inhabiting the Horn of Africa. They primarily live in the Afar Region of Ethiopia and in northern Djibouti, as well as the entire southern coast of Eritrea. The Afar speak the Afar language, which is part of the Cushitic branch of the Afroasiatic family. Afars are the only inhabitants of the Horn of Africa whose traditional territories border both the Red Sea and the Gulf of Aden. History Early history The earliest surviving written mention of the Afar is from the 13th-century Andalusian writer Ibn Sa'id, who reported that they inhabited the area around the port of Suakin, as far south as Mandeb, near Zeila. They are mentioned intermittently in Ethiopian records, first as helping Emperor Amda Seyon in a campaign beyond the Awash River, then over a century later when they assisted Emperor Baeda Maryam when he campaigned against their neighbors the Dobe'a.
