The “eye” is the trademark characteristic of a mature tropical cyclone (also called a hurricane or typhoon). While temperate cyclones have low-pressure centers, they rarely develop the clear, calm and well-defined circular eye that tropical cyclones do. This feature is ...

The Geostrophic wind occurs in the upper atmosphere where friction from the Earth’s surface is absent. It represents a perfect balance where the Pressure Gradient Force (pushing air toward low pressure) is exactly equaled by the Coriolis Force (pulling air ...
The Roaring Forties are powerful westerly winds found in the Southern Hemisphere between 40° and 50° latitude. They are caused by air moving from subtropical highs toward the poles. Because the Southern Hemisphere has very little land to slow the ...
The troposphere is the warmest layer relative to the layers immediately above it because it is heated directly by the Earth’s surface. Sunlight passes through the air and warms the ground, which then radiates heat back into the lower atmosphere. ...
The maximum height of the troposphere is approximately 18 km, which is typically reached at the equator. The intense solar heating at equatorial regions causes the air to become very warm and expand significantly, pushing the boundary of the troposphere ...
