Joint Seminar: The Stirring Tropics
Over the tropics, column water vapor has been found to be highly correlated with precipitation, especially in slowly evolving systems. The observations and theory support the hypothesis that moisture modes exist, a type of precipitating weather system that does not exist in dry theory. Our results show that all oceanic Tropical Depression (TD)-like waves and Equatorial Rossby waves are moisture modes. These systems exist in regions where moisture varies greatly in space, and they grow by transporting air from the humid areas of the tropics toward their low-pressure center. These results suggest that the climatological-mean distribution of moisture in the tropics is unstable and is subject to stirring by moisture modes.
