Tropical Climates

Found within Africa's tropical zone due to its position near the equator, tropical climates generally experience warm temperatures and significant rainfall. They also hold a large proportion of the continent's landmass.

Types of Tropical Climates

Tropical Africa has 2 subtypes: Equatorial, characterized by year-round high temperatures and high rainfall, and Savanna, marked by a distinct wet season and a dry season.

Convectional Rainfall

Rainfall that occurs when warm, moist air rises, cools, and condenses, forming clouds and causing precipitation. This is the primary source of rainfall in Equatorial Africa.

Mozambique Current

A warm ocean current flowing along the east coast of Africa, influencing the savanna climate by bringing warmer temperatures and increasing rainfall year-round.

Why is Africa mainly tropical?

About 70% of Africa lies between the tropics, meaning it receives high solar energy throughout the year, leading to warm temperatures.

How does savanna climate differ from equatorial?

Savanna is a transition zone, experiencing warm temperatures year-round, but with distinct wet and dry seasons. It is influenced by the warm Mozambique current.

Study Notes

Africa's Climate Zones

  • Africa's climate is influenced by its position over the equator, proximity to land and sea, topography, and ocean currents.
  • Approximately 70% of Africa lies between the tropics, leading to predominantly tropical climates.
  • There are 3 main climate categories: tropical, semi-desert & dryland, and humid mid-latitude.
  • Tropical climates include equatorial and savanna regions.
  • Semi-desert & dryland climates include semi-desert and desert regions.
  • Humid mid-latitude climates include Mediterranean, highveld, and humid subtropical regions.

Equatorial Climate

  • Found between 6°—7° north & south of the equator.
  • Characterized by high temperatures throughout the year due to the high solar angle.
  • Receives convectional rainfall, often thunderstorms, caused by intense daytime heat.
  • Experiences high annual rainfall.

Savanna Climate

  • Found between 5°—15° north & south of the equator.
  • A transitional zone between equatorial and desert climates.
  • Summers are characterized by hot temperatures and rainfall.
  • Winters are cool and dry.
  • The dry season is characterized by a progressive decline in rainfall, lasting 3-8 months in Tanzania.
  • Warm temperatures year-round due to the warming effect of the Mozambique current.
  • High annual rainfall throughout most of the year.

Semi-Arid Climate

  • Winters are cold and dry.
  • Rainfall occurs during the summer months.
  • Found on the dry sides of savanna regions and in areas like the Namibian Sahara.
  • Summers are very hot, exceeding 32°C.

Desert Climate

  • Winters are warm.
  • Experience very high temperatures.
  • Receives little to no rainfall.
  • Characterized by low humidity.

Highveld Climate

  • Located in the highveld of South Africa.
  • The smallest of all the climatic zones.
  • Experiences summer rainfall.
  • Winters are dry and sunny.

Situated on a plateau at high altitudes.

Mediterranean Climate

  • found in the northern and southern tips of africa
  • experiences hot, dry and sunny summers

experiences warm wet and moist winters --> had rainfall in winter due to ocean currents that bring rain.

Humid Subtropical

  • occurs in southeast Africa (Durban)
  • year-round rainfall (that is heavier in summer)
  • summers = long hot and humid
  • daily, intense but brief convective thunder showers
  • winter temperatures are mild or slightly above freezing
