Zimbabwe is a landlocked country in southern Africa lying north of the Tropic of Capricorn. During summer, the whole country experiences warm temperatures as a result of the sun being directly overhead. It straddles an extensive high inland plateau that drops northwards to the Zambezi valley where the border with Zambia is and similarly drops southwards to the Limpopo valley and the border with South Africa. The country has borders with Botswana 813 km, Mozambique 1,231 km, South Africa 225 km, Zambia 797 km and almost meets Namibia at its westernmost point. The highest point is at 2 592m (Mt Inyangani) Climate The climate is markedly varied by altitude with the Eastern Highlands 1878m above sea level being much wetter and cooler. There is a dry season, including a short cool season during the period May to September when the whole country has very little rain. The rainy season is typically a time of heavy rainfall from November to March. The whole country is influenced by the Intertropical Convergence Zone during January. In years when it is poorly defined there is below-average rainfall and a likelihood of serious drought in the country, as happened in 1983 and 1992. When it is well defined rainfall is average or well above average, as in 1981 and 1986. the climate can be categorised into three regions, hot region (lowveld and part of the middleveld), warm region (rest of the middleveld and high veld) and the cool region (Eastern Highlands) Examples Terrain Much of the country is on a plateau with a higher central plateau (high veld) forming a watershed between the Zambezi and Limpopo river systems. The flattish watershed region is part of an ancient etchplain called the African Surface covers large swathes of the continent. While the African Surface occupy the higher ground, spurs and small interfluves a younger "post-African" surface occupy lower positions with occasional rock domes, koppies and tors protruding rolling or plain landscape. The Limpopo and the lower Zambezi valleys are broad and relatively flat plains. The eastern end of the watershed terminates in a north-south mountain spine, called the Eastern Highlands. The northeast-southwest oriented central uplands have been uplifted in geologically recent times (Late Pliocene or Pleistocene) deviating the watercourse of upper Zambezi River that used to flow into the Limpopo River to the east to its current outlet at the Mozambique Channel.
