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 ...

Cyclones are complex storms born from atmospheric instability. They often form when two contrasting air masses—one warm and moist, the other cold and dry—collide. This meeting creates a “front” where the air begins to spiral due to pressure changes. Essentially, ...
Dry air cools at about 10°C per kilometer (DALR). However, when rising air is saturated, water vapor condenses into liquid droplets. This chemical change releases “latent heat” into the air parcel. This extra heat partially offsets the cooling process, making ...
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 ...
This is the technical definition of trade winds. They are the surface winds of the tropical atmospheric circulation. They move from the high-pressure “Horse Latitudes” (subtropical highs) to the low-pressure “Doldrums” (equatorial lows). Because of the Coriolis effect, they blow ...
