Tropical Wave - Another name for an easterly wave, it is an area of relatively low pressure moving westward through the trade wind easterlies.

An example of this was This entry is from Wikipedia, the leading user-contributed encyclopedia. These can lead to the formation of a tropical cyclone. Many tropical waves are generated by the African Easterly Jet (AEJ), an east-to-west oriented wind (much like the By providing the initial energy and spin needed for a The majority of hurricanes form from tropical waves.

Tropical waves, often called African easterly waves, are the building blocks for much of the tropical storm and hurricane activity in the Atlantic and even Pacific basins.

"The weather out ahead (west) of a tropical wave is typically fair.

Ladwig, William C.; Stensrud, David J. When you hear "tropical wave", you probably picture a wave crashing against the shore of a tropical island beach. an elongated area of relatively lower air pressure that is typically oriented north to south. an offensive content(racist, pornographic, injurious, etc.) This yields widespread showers and thunderstorms, sometimes severe. This normally occurs if upper-level If a tropical wave is moving quickly, it can have strong winds of over tropical storm force, but is not considered a tropical storm unless it has a closed circulation.

After the passage of the trough line, the wind veers southeast, the humidity abruptly rises, and the atmosphere destabilizes. Advertizing Wikipedia. Many tropical waves are generated by the African Easterly Jet (AEJ), an east-to-west oriented wind (much like the jet stream) that flows across Africa into the tropical Atlantic Ocean.The wind near the AEJ moves faster than the surrounding air, causing eddies (small whirlwinds) to develop.

To put that more simply, it's a weak trough of low pressure that develops from an unorganized cluster of thunderstorms. Eventually, the wave can become a hurricane. Tropical waves last from a couple of days to several weeks, with new waves forming every few days. Once a tropical disturbance becomes more organized, it can be called a tropical depression. As the wave moves westward, the showers gradually diminish.An exception to this rain is in the Atlantic. By using our services, you agree to our use of cookies.
