Difficulty: EasyClimate and Climatic Regions of Nigeria

Arrange the following climatic zones of Nigeria in order from SOUTH to NORTH, starting from the Atlantic coast and moving toward the northern boundary.

  1. 1Sub-equatorial climate zone
  2. 2Tropical Hinterland climate zone
  3. 3Tropical Continental (Sudan) climate zone
  4. 4Sahelian climate zone

Answer

The correct order from South to North is: Sub-equatorial climate zone, Tropical Hinterland climate zone, Tropical Continental (Sudan) climate zone, and Sahelian climate zone.
Nigeria's climatic regions display a clear latitudinal pattern from south to north driven by proximity to the Atlantic Ocean and the seasonal migration of the Inter-Tropical Discontinuity. Starting at the coast in the south and moving north toward the Sahara, the sequence progresses from the Sub-equatorial coastal climate, through the Tropical Hinterland climate, into the Tropical Continental (Sudan) climate, and terminates at the semi-arid Sahelian climate zone.

Step-by-Step Solution

1
Identify the coastal climatic zone in the far south of Nigeria.
The Sub-equatorial climate zone occupies the coastal belt along the Atlantic Ocean.
Proximity to the ocean ensures maximum exposure to moist maritime tropical air masses.
2
Identify the climatic zone directly inland from the coast.
The Tropical Hinterland climate zone forms the next belt moving northward.
This region experiences slightly less total annual rainfall than the coast with a short dry period.
3
Identify the extensive climate zone covering northern Nigeria.
The Tropical Continental climate zone spans across the northern savanna plains.
Distance from the sea increases, leading to lower rainfall totals and longer dry seasons.
4
Identify the climatic zone along Nigeria's northernmost boundary.
The Sahelian climate zone lies along the far northern border near the Sahara region.
It receives the least annual precipitation due to the brief presence of moisture-bearing winds at high latitude.
