Impacts of Turbulence on Hurricane Intensity

Abstract

Our recent studies have shown that hurricane boundary layer turbulence, which must be parameterized in the current-generation weather-prediction models, plays a significant role in controlling the hurricane intensity. We find that horizontal turbulence, particularly in the radial direction (i.e., towards or away from the hurricane center), plays an important role in regulating hurricane intensity. The long-term goal of this project is thus to improve the hurricane intensity forecast by developing a more physically based horizontal turbulence parameterization scheme for hurricanes.
