The Hot, Wet Equatorial Climate

Distribution:

  • It is found between 5° and 10° north and south of the equator.
  • It is dominantly found in the lowlands of the Amazon, the Cango, Malaysia and the East Indies.

Climate:

  • There is great uniformity of temperature through out the year.
  • The mean monthly temperatures are always around 24 to 27°C, with very little variation.
  • There is no winter.
  • Precipitation is heavy between 60 inches and 10 inches, and well distributed throughout the year.

Natural Vegetation

  • It support a luxuriant type of vegetation – the tropical rain forest.
  • Amazon tropical rain forest is known as Selvas.
  • It comprises a multitude of evergreen trees that yield tropical hardwood, e.g. mahogany, ebony, greenheart, cabinetwood, and dyewoods.

Economy

  • In the forests, most primitive people live as hunters and collectors and the more advanced ones practice shifting cultivation.
  • Some plantation crops are also practiced like natural rubber, cocoa, etc.

The Tropical Monsoon and Tropical Marine Climates

Distribution:

  • It is found in the zones between 5° and 30° latitudes on either side of the equator.
  • It is best developed in the Indian subcontinent, Burma, Thailand, Laos, Cambodia, parts of Vietnam and South China and northern Australia.
  • Tropical Marine climate is found in Central America, West Indies, the Philippines, parts of East Africa, West Indies, the Philippines, parts of East Africa, Madagascar, the Guyana coast and eastern Brazil.

Climate

  • Though mean annual temperature is fairly high but summer and winter seasons are sharply differentiated due to northward and southward movement of the sun.
  • The average annual rainfall is around 150 cm but there are much variations in the temporal and spatial distribution.

Natural Vegetation

  • Most of the forests yield valuable timber like teak. Other kinds of timber are sal, acacia and eucalyptus.

Economy

  • People are mainly engaged in agriculture.

The Hot Disert and Mid-Latitude Desert Climates

Distribution

  • The major hot deserts of the world are located on the western coasts of continents between latitudes 15° and 30°N and S.

Climate

  • The relative humidity is extremely low, decreasing from 60 per cent in coastal districts to less than 30 per cent in coastal districts to less than 30 per cent in the desert interiors.
  • Rain normally occurs as violent thunderstorms of the convectional type.
  • The highest shade temperature recorded is 136°F on the 13 September 1922 at Al Azizia, 25 miles south of Tripoli, Libya, in the Sahara.

Natural Vegetation

  • All deserts have some form of vegetation such as grass, crub, herbs, weeds, roots or bulbs.

Economy

  • The Bushmen of the Kalahari and the Bindibu of Australiar remain so primitive in their mode of living that they barely survive.
  • Both the tribes are nomadic hunters and food gatherers, growing no crops and domesticating no animals.

Mediterranean Climate

Distribution

  • This climate type prevails in much of California, in parts of Western and South Australia, in southwestern South Africa and in parts of central Chile.

Climate

  • The climate is characterized by hot, dry summers and cool, wet winters.
  • Since all regions with a Mediternean climate are near large bodies of water, temperatures are generally moderate with a comparatively small range of temperatures between the winter low and summer high.
  • During summer, regions of Mediterranean climate are dominated by subtropical high pressure cells causing no or little rainfall.
  • During winter the polar jet stream and associated periodic storms reach into the lower latitudes of the Mediterranean zones, bringing rain, with snow at higher elevations.

Natural Vegetation

  • Evergreen coniferous trees are pines, firs, cedars and cypresses.

Economy

  • Nowadays, the area is important for fruit cultivation, cereal growign, wine-making and agricultural industries as well as engineering and mining.
  • The Mediterranean lands are also known as the worl’s orchard lands.
  • Cereals are also grown in the Mediterranean lands. Wheat is the leading food crop. The wheat grown is mainly hard, winter wheat.

The Savanna or Sudan Climate

Distribution

  • It is located between 5°-20° latitudes on either side of the equator.
  • The most characteristic areas of savanna climate include the Llanos of Orinico valley, the Campos of Brazil, hillyareas of central America, southern Zaire, etc.

Climate

  • The Savanna climate is characterized by distinct wet and dry seasons.
  • Mean high temperature throughout the year is between 24°C and 27°C.
  • The average annual rainfall ranges between 100 cm and 150 cm.

Natural Vegetation

  • It is characterized by tall grass and short trees.

Economy

  • Some tribes live as pastoralists like the Masai and other as settled cultivators like the Hausa of northern Nigeria.
  • However, agriculture is not much developed.

The Temperate Continental (Steppe) Climate

Distribution

  • Bordering the deserts, away from the Mediterranean regions and in the interiors of continents are the temperate grasslands.
  • In Eurasia, they are called the Steppes.

Climate

  • Their climate is continental with extremes of temperature.
  • Summers are very warm.
  • Winters are very cold in the continental steppes of Eurasia.
  • The average rainfall may be taken as about 20 inches.

Natural Vegetation

  • The term ‘steppe vegetation’ geographically refers to the scanty vegetation of the subarid lands of continental Eurasia.
  • Their greatest difference from the tropical savanna is that they are practically treeless and the grasses are much shorter.

Economy

  • The grasslands have been ploughed up for extensive, mechanized wheat cultivation and are now the ‘granaries of the world’. Besides wheat, maize is increasingly cultivated in the warmer and wetter area.

Warm Temperate Eastern Margin (China Type) Climate

Distribution

  • This type of climate is found on the eastern margins of continents in warm temperate latitudes, just outside the tropics.
  • It is, in fact, the climate of most part of China-a modified form of monsoonal climate. It is thus also called the (Temperate Monsoon) or China Type of climate.

Climate

  • The Warm Temperate Eastern Margin Climate is typified by a warm moist summer and a cool, dry winter.
  • The mean monthly temperature varies between 40°F and 78°F and is strongly modified by maritime influence.
  • Rainfall is more than moderate, anything from 25 inches to 60 inches.

Natural Vegetation

  • The eastern margins of warm temperate latitudes have a much heavier rainfall than either the western margins or the continental interiors and thus have a luxuriant vegetation.
  • Conditions are well suited to a rich variety of plant life including grass, ferns, lianas, bamboos, palms and forests.

Economy

  • Rice, tea and mulberries are extensively grown in monsoon China.
  • Elsewhere are found other products of economic importance, e.g. can sugar in Natal, coffee and maize in South America and dairying in New South Wales and Victoria.
