The azimuthally averaged boundary layer structure of a numerically simulated major hurricane
This work examines the azimuthally averaged boundary layer structure of a numerically simulated hurricane. We nominally define the hurricane boundary layer as the layer in which the effects of surface friction are associated with significant departures from gradient wind balance. The boundary layer in the intensifying primary and forming secondary eyewalls is found to be nonlinear. At large rad...
متن کاملCoyote unmanned aircraft system observations in Hurricane Edouard (2014)
Horizontal wind, temperature, and moisture observations are presented from two Coyote unmanned aircraft system (UAS) flights in the boundary layer of Hurricane Edouard (2014). The first flight sampled the meteorological conditions in the eye and eyewall at altitudes from 900 to 1500m while Edouard was a major hurricane (105 kt) on 16 September 2014. The following day, a second Coyote sampled th...
متن کاملAssessing Hurricane Intensity Using Satellites
Tropical cyclones spend most of their life cycle over the tropical and subtropical oceans. Because of the lack of in situ data in these regions, satellite observations are fundamental for tracking and estimating the intensity of these storms for real-time forecasting and monitoring climate trends. This chapter reviews methods for estimating tropical cyclone intensity from satellites, including ...
متن کاملHurricane intensity and eyewall replacement.
Observations made during the historic 2005 hurricane season document a case of "eyewall replacement." Clouds outside the hurricane eyewall coalesce to form a new eyewall at a greater radius from the storm center, and the old eyewall dies. The winds in the new eyewall are initially weaker than those in the original eyewall, but as the new eyewall contracts, the storm reintensifies. Understanding...
متن کاملImpacts of Turbulence on Hurricane Intensity
Because of the multi-scale nature of hurricanes, the proposed large-eddy simulation work is also a challenging computational problem. A three-dimensional research cloud model (CM1) with horizontal grid stretching capability is used to conduct convergence test. The Weather Research and Forecasting (WRF) model is used as a weather-prediction model to examine the eddy-diffusion coefficients obtain...
