Global Winds - Summary and Worksheet

Friday, April 11, 2025

 


Unequal Heating and Pressure Systems: The Earth's tilt causes uneven solar heating, creating high-pressure zones (colder, denser air) at the poles and 30° latitude, and low-pressure zones (warmer, less dense air) at the equator and 60° latitude. This pressure difference drives air movement. • Coriolis Effect and Prevailing Winds: The Earth's rotation (Coriolis effect) deflects wind patterns, creating three main prevailing wind belts: polar easterlies (60°–90° latitude), westerlies (30°–60° latitude), and trade winds (equator–30° latitude). These winds are named for the direction *fromwhich they originate.Windless Zones: The doldrums (near the equator) and horse latitudes (around 30° latitude) experience minimal wind due to rising air (doldrums) and diverging high-pressure systems (horse latitudes). These zones historically posed challenges for sailors relying on wind for travel.
