The Intertropical Convergence Zone (ITCZ) is a low-pressure belt that encircles the Earth near the Equator, where the trade winds of the Northern and Southern Hemispheres converge. It is characterized by convective activity, leading to frequent thunderstorms and heavy rainfall.

Isonephs are lines on a weather map that connect points of equal cloudiness.

Four local winds are:

• Harmattan
• Sea breeze
• Land breeze
• Chinook

A wind vane is a meteorological instrument used to indicate the direction from which the wind is blowing. It typically consists of a freely rotating horizontal arm with a fin at one end and a pointer at the other, mounted on a vertical shaft. The fin catches the wind, causing the arm to align itself with the wind direction, and the pointer indicates the direction on a fixed compass rose below it. (A diagram would typically show a vertical pole with a horizontal arrow-shaped component on top, free to rotate. The tail of the arrow would be a fin, and the head would point towards the wind's origin. Below the arrow, a fixed compass rose (N, S, E, W) would be visible.)

The main vegetation zones in Nigeria are:
