The Brown Ocean Effect
Before Tropical Storm Bill made landfall over Texas, eastern Texas experienced several days of rain that began flooding areas to the south east and northern parts of the state. As Tropical Storm Bill moved northward through Texas it is hypothesized that it fed off the highly saturated ground (as if it were still over the ocean) and can be seen slightly intensifying (via winds) as it moved into Oklahoma and progressed to the northeast.
In several regions of the world, tropical cyclones have been known to maintain or increase strength after landfall without transitioning to extratropical systems. It is hypothesized that these inland areas help sustain tropical cyclones when there has been plentiful rainfall, leading to unusually wet soil and strong latent heat release. Additionally, given the symmetric structure of warm-core cyclones, the atmosphere should tend toward barotropic conditions that mimic an ocean environment. Observational and modeling studies support this "brown ocean" concept, providing a global climatology of inland tropical cyclones, pinpointing regions that are more favorable for re-intensification, and analyzing individual cyclones to better understand the associated land-atmosphere feedbacks.
