These " Cape Verde storms" then take the long voyage for 1 to 2 weeks across the Atlantic Basin, sometimes affecting the Caribbean Sea, Gulf of Mexico and or the eastern U.S. Sometimes tropical cyclones develop soon after the parent tropical wave emerges off Africa, near the Cape Verde Islands. On the other hand, some tropical waves cross the entire Atlantic Ocean and Caribbean Sea without triggering tropical cyclone development. Furthermore, about 60 percent of all tropical storms and Category 1 and 2 hurricanes are spawned by these waves. It turns out roughly 85 percent of all Atlantic major hurricanes have origins traceable to African easterly waves. ![]() Major hurricanes (Category 3 or higher on the Saffir-Simpson hurricane wind scale) are typically responsible for the majority of damage in any hurricane season. These tropical waves play a very important role in hurricane formation. You can see tropical waves on infrared satellite imagery as clusters of convection originating over north Africa, then pushing westward in the tropical Atlantic Ocean. ![]() What results are what we refer to as "tropical waves", discrete areas of horizontal spin in the low to mid-levels of the atmosphere. ![]() "Similiar to winds blowing over the ocean creating fairly evenly-spaced up-and-down waves in the water, this African easterly jet gets a little unstable every few days," says Hurricane Expert at The Weather Channel and former National Hurricane Center Director, Dr. This means the north-south temperature contrast we mentioned results in a jet stream moving from east to west across the continent into the tropical Atlantic Ocean, the so-called "African easterly jet." Unlike jet streams affecting the mid-latitudes of the northern hemisphere, this jet stream is located only about 10,000 feet above the ground. A basic tenet of meteorology is that horizontal temperature contrasts lead to vertical contrasts in wind. ![]()
