    HOT CLIMATE (EQUATORIAL CLIMATE) Location: The equatorial climate is located within 5˚ north and south of the equator. Areas: Amazon Basin of South America. The Zaire Basin of Central Africa. The coasts of West Africa. Characteristics of the Climate An equatorial climate exhibits the following characteristics: The temperature of an equatorial climate is constantly high all the year round. The mean monthly temperature is 27˚C. There is very small annual range (less than 3˚C). The humidity is high. Relative humidity is over 80%, i.e. high relative humidity. There is the presence of large amount of clouds in the sky. The daily range of temperature is small. The annual rainfall is…

    CLASSIFICATION OF CLIMATE

    Classification of climate is a conscious attempt at group different climates with similar characteristics together. This is because climate varies from place to place. The common systems of classification of climate include the Greeks and Koppen’s classifications.   Greek System of Classification of Climate This is one of the earliest, ordinary, simple and rough climatic classifications put forward by the Greek people. The basis for the Greek classification is Temperature. This system divides the world into three climatic zones which include: Torrid zone This zone is found within the tropics. The zone is very hot. It has high temperature throughout the year.   Temperate zone This zone is found between…

    MAJOR HYDRO-ELECTRIC POWER PROJECTS IN AFRICA

    Hydro-Electric Power (H.E.P) is the generation of electric power (electricity) from water. This is achieved through the damming of rivers and the use of river water to turn or drive turbines leading to the generation of electricity. A dam is an extensive area occupied by water trapped on a river course.   FACTORS WHICH FAVOUR THE DEVELOPMENT OF HYDRO-ELECTRIC POWER (H.E.P) PROJECTS IN AFRICA Presence of relief/waterfalls ensures the development of Hydro-Electric Power. Abundance of rainfall in Africa also helps to supply water to rivers regularly. There is also high volume of water in rivers which is necessary for Hydro-Electric Power development i.e. presence of a big river. Presence of…
