Garúa
Garúa is a Spanish word meaning drizzle or mist. Although used in other contexts in the Spanish-speaking world, garúa most importantly refers to the moist cold fog that blankets the coasts of Peru, southern Ecuador, and northern Chile, especially during the southern hemisphere winter. In Chile, a similar fog is called camanchaca. Garúa brings mild temperatures and high humidity to a tropical coastal desert. It also provides moisture from fog and mist to a nearly-rainless region and permits the existence of vegetated fog oases, called lomas. While fog and drizzle are common in many coastal areas around the world, the prevalence and persistence of garúa and its impact on climate and the environment make it unique. Formation The cold waters of the Humboldt Current are responsible for both the coastal deserts and the garúa along the coasts of Peru and Chile from latitudes 5° to 30° South, a north-south distance of . Between those latitudes, the Humboldt Current hugs the co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lomas
Lomas (Spanish for "hills"), also called fog oases and mist oases, are areas of fog-watered vegetation in the coastal desert of Peru and northern Chile. About 100 lomas near the Pacific Ocean are identified between 5°S and 30°S latitude, a north–south distance of about . Lomas range in size from a small vegetated area to more than and their flora includes many endemic species. Apart from river valleys and the lomas the coastal desert is almost without vegetation. Scholars have described individual lomas as "an island of vegetation in a virtual ocean of desert." In a nearly rainless desert, the lomas owe their existence to the moist dense fog and mist which rolls in from the Pacific. The fog is called garúa in Peru and Camanchaca in Chile. Environment According to the Köppen Climate Classification system, the coastal desert of Peru and the Atacama desert of Chile feature a rare desert climate, that is abbreviated "BWn" on climate maps with the n denoting frequent fog ...

Lima, Peru
Lima ( ; ), originally founded as Ciudad de Los Reyes (City of The Kings) is the capital and the largest city of Peru. It is located in the valleys of the Chillón, Rímac and Lurín Rivers, in the desert zone of the central coastal part of the country, overlooking the Pacific Ocean. Together with the seaside city of Callao, it forms a contiguous urban area known as the Lima Metropolitan Area. With a population of more than 9.7 million in its urban area and more than 10.7 million in its metropolitan area, Lima is one of the largest cities in the Americas. Lima was named by natives in the agricultural region known by native Peruvians as ''Limaq''. It became the capital and most important city in the Viceroyalty of Peru. Following the Peruvian War of Independence, it became the capital of the Republic of Peru (República del Perú). Around one-third of the national population now lives in its metropolitan area. The city of Lima is considered to be the political, cultural, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Of Chile
The climate of Chile comprises a wide range of weather conditions across a large geographic scale, extending across 38 degrees in latitude, making generalizations difficult. According to the Köppen system, Chile within its borders hosts at least seven major climatic subtypes, ranging from low desert in the north, to alpine tundra and glaciers in the east and southeast, tropical rainforest in Easter Island, Oceanic in the south and Mediterranean climate in central Chile. There are four seasons in most of the country: summer (December to February), autumn (March to May), winter (June to August), and spring (September to November). On a synoptic scale, the most important factors that control the climate in Chile are the Pacific Anticyclone, the southern circumpolar low pressure area, the cold Humboldt current, the Chilean Coast Range and the Andes Mountains. Despite Chile's narrowness, some interior regions may experience wide temperature oscillations and cities such as Sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camanchaca
Camanchacas are marine stratocumulus cloud banks that form on the Chilean coast, by the Earth's driest desert, the Atacama Desert, and move inland. In Peru, a similar fog is called garúa, and in Angola cacimbo. On the side of the mountains where these cloud banks form, the camanchaca is a dense fog that does not produce rain Rain is water droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water .... The moisture that makes up the cloud measure between 1 and 40 microns across, too fine to form rain droplets. Fog collection In 1985, scientists devised a fog collection system of polyolefin netting to capture the water droplets in the fog to produce running water for villages in these otherwise desert areas. The Camanchacas Project installed 50 large fog-collecting nets on a mountain ridge, which ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Peru
Peru is a country on the central western coast of South America facing the Pacific Ocean. It lies wholly in the Southern Hemisphere, its northernmost extreme reaching to 1.8 minutes of latitude or about south of the equator. Peru shares land borders with Ecuador, Colombia, Brazil, Bolivia, and Chile, with its longest land border shared with Brazil. Statistics Area: Peru has a total land area of 1,379,999 km² and a total water area of 5,000 km². Maritime claims: ''Continental shelf:'' ''Territorial sea:'' '' Exclusive economic zone:'' Land use: Only 3% of Peru's land is arable, with 0.5% being suitable for permanent crops. Permanent pastureland accounts for 21% of Peru's land use, and forests and woodland accounting for 66% of the landscape. Approximately 9.5% (1993 est.) of Peruvian land is attributed to population centers, coastal regions, and other space. Irrigated land: 12,800 km² (1993 est.)

Atiquipa District
Atiquipa District is one of thirteen districts of Caravelí Province in the Arequipa Region of Peru. Environment Atiquipa is located in the coastal desert of Peru, an almost rainless area. However, heavy fogs and mists, called garúa, permit vegetation to grow on the mountain slopes of the district. This vegetated fog oasis is called the Lomas de Atiquipa, It is the largest and the best preserved fog oasis in Peru, covering more than with some 350 plant species, including 44 endemics. Conservation organizations are attempting to preserve and restore the environment of the lomas. Included in the project is the installation of fog-catching nets to capture water and thereby help the 80 families who live within the area to expand agriculture, primarily growing olive The olive, botanical name ''Olea europaea'', meaning 'European olive' in Latin, is a species of small tree or shrub in the family Oleaceae, found traditionally in the Mediterranean Basin.

Fog Collection
upright=1.3, ''Atrapanieblas'' or fog collection in Atacama_Desert.html" ;"title="Alto Patache, Atacama Desert">Alto Patache, Atacama Desert, Chile Fog collection is the harvesting of water from fog using large pieces of vertical mesh netting to induce the fog-droplets to flow down towards a trough below. The setup is known as a fog fence, fog collector or fog net. Through condensation, atmosphere, atmospheric water vapour from the air condenses on cold surfaces into droplets of liquid water known as dew. The phenomenon is most observable on thin, flat, exposed objects including plant leaves and blades of grass. As the exposed surface cools by radiating its heat to the sky, atmospheric moisture condenses at a rate greater than that of which it can evaporate, resulting in the formation of water droplets. Water condenses onto the array of parallel wires and collects at the bottom of the net. This requires no external energy and is facilitated naturally through temperature fluct ...

Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest mountain ra ...

Deserts Of Peru
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Chile
The geography of Chile is extremely diverse as the country extends from a latitude of 17° South to Cape Horn at 56° and from the ocean on the west to Andes on the east. Chile is situated in southern South America, bordering the South Pacific Ocean and a small part of the South Atlantic Ocean. Chile's territorial shape is among the world's most unusual. From north to south, Chile extends , and yet it only averages east to west. Chile reaches from the middle of South America's west coast straight down to the southern tip of the continent, where it curves slightly eastward. Diego Ramírez Islands and Cape Horn, the southernmost points in the Americas, where the Pacific and Atlantic oceans meet, are Chilean territory. Chile's northern neighbors are Peru and Bolivia, and its border with Argentina to the east, at , is the world's third-longest. The total land size is . The very long coastline of gives it the 11th largest exclusive economic zone of . Physical geography The n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloud Types
The list of cloud types groups all genera as ''high'' (cirro-, cirrus), ''middle'' (alto-), ''multi-level'' (nimbo-, cumulo-, cumulus), and ''low'' (strato-, stratus). These groupings are determined by the altitude level or levels in the troposphere at which each of the various cloud types is normally found. Small cumulus are commonly grouped with the low clouds because they do not show significant vertical extent. Of the multi-level genus-types, those with the greatest convective activity are often grouped separately as ''towering vertical''. The genus types all have Latin names. The genera are also grouped into five physical forms. These are, in approximate ascending order of instability or convective activity: ''stratiform'' sheets; ''cirriform'' wisps and patches; ''stratocumuliform'' patches, rolls, and ripples; ''cumuliform'' heaps, and ''cumulonimbiform'' towers that often have complex structures. Most genera are divided into ''species'' with Latin names, some of which are c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
