The origin of trade winds is tied to the Hadley Cell circulation. Near 30° North and South latitudes, air that rose at the equator has cooled and moved poleward; it then descends toward the Earth's surface. This descending air creates a "piling up" effect, resulting in high-pressure zones. Since airRead more
The origin of trade winds is tied to the Hadley Cell circulation. Near 30° North and South latitudes, air that rose at the equator has cooled and moved poleward; it then descends toward the Earth’s surface. This descending air creates a “piling up” effect, resulting in high-pressure zones. Since air always moves from high to low pressure, it rushes back toward the heat-induced low at the equator. This constant supply of sinking air at the subtropics ensures that the trade winds remain the most consistent and permanent wind system on the planet.

The Westerlies blow from the subtropical highs toward the subpolar lows. In the Southern Hemisphere, they are particularly fierce because there is very little land to act as a “windbreak.” As a result, these winds grow progressively stronger as you move further south. Sailors historically used these winds to race across the globe, naming the latitudes based on the sound and intensity of the wind: the “Roaring” 40s, the “Furious” 50s and the “Shrieking” or “Screaming” 60s. They remain some of the most consistent and powerful wind belts on Earth.

This term describes the persistent westerly winds that dominate the Southern Ocean.

This term describes the persistent westerly winds that dominate the Southern Ocean. Unlike the Northern Hemisphere, where continents like Eurasia and North America create friction that breaks up wind patterns, the Southern Hemisphere is mostly water. This lack of physical obstacles allows the winds to build up incredible momentum. The Roaring Forties are essential for the global climate as they help drive major ocean currents and distribute heat around the planet. Historically, they were a double-edged sword for sailors: they allowed ships to travel very fast across the ocean, but the violent waves and stormy weather made navigation extremely dangerous.

Found between the latitudes of 50° and 60° South, the Furious Fifties represent one of the most volatile wind belts on Earth.

Found between the latitudes of 50° and 60° South, the Furious Fifties represent one of the most volatile wind belts on Earth. These winds are driven by the massive temperature contrast between the tropical regions and the icy Antarctic continent. Because there is absolutely no landmass at this latitude to obstruct the airflow, the winds can reach hurricane-force speeds. For students of geography, this region is a perfect example of how surface friction—or the lack thereof—impacts atmospheric velocity. These winds are a major component of the “West Wind Drift,” the largest ocean current in the world.

At 60° South latitude, the atmosphere encounters the "Screaming" or "Shrieking" Sixties. These winds are located in the subpolar low-pressure belt. The unique atmospheric conditions here involve extremely cold air rushing to meet warmer air from the north, creating intense low-pressure systems. TheRead more
At 60° South latitude, the atmosphere encounters the “Screaming” or “Shrieking” Sixties. These winds are located in the subpolar low-pressure belt. The unique atmospheric conditions here involve extremely cold air rushing to meet warmer air from the north, creating intense low-pressure systems. The term “shrieking” comes from the sound the wind makes as it passes through a ship’s rigging. For children learning about the globe, it is important to note that these winds are restricted to the South because the North Pole is surrounded by land, which prevents such uniform and violent wind belts from forming.
