Trade winds are a type of planetary wind.

Planetary winds, also known as prevailing winds, are large-scale, relatively constant wind patterns that blow across the globe due to differences in air pressure and the Earth’s rotation. Trade winds (blowing from subtropical high-pressure belts towards the equatorial low-pressure belt), Westerlies (blowing from subtropical highs towards subpolar lows), and Polar Easterlies (blowing from polar highs towards subpolar lows) are primary examples.

Monsoons are seasonal winds driven by differential heating of land and sea, not constant global patterns. Chinook and Mistral are examples of local winds influenced by topography and regional pressure systems.
