STORM2K

What does enso mean and what does it stand for? Also what does TUTT mean? Im trying to get into the swing of things again because I have not been on here in a while. Now since im now finished with college,I can devote my time again to the upcoming hurricane season.
Its good to be back.

Here are the answers to both questions.

ENSO=El Nino Southern Occillation

TUTT=Tropical Upper Tropospheric Trough

thanks!
