Impacts of Turbulence on Hurricane Intensity

چکیده
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 obtained from CM1 simulation in both idealized and real-data hurricane cases.

NOTES AND CORRESPONDENCE Comments on “Impacts of CO2-Induced Warming on Simulated Hurricane Intensity and Precipitation: Sensitivity to the Choice of Climate Model and Convective Scheme”
In a simulation of enhanced tropical cyclones in a warmer world, Knutson and Tuleya make several assumptions that are not borne out in the real world. They include an unrealistically large carbon dioxide growth rate, an overly strong relationship between sea surface temperature and hurricane intensity, and the use of a mesoscale model that has shown little to no useful skill in predicting curre...
متن کاملInvestigation of Air Turbulence Intensity Effect on the Flame Structure in Different Flame Holder Geometry
In this paper, the effect of air turbulence intensity on the flame structure in various radii and lengths of a flame holder numerically studied. Finite volume method is used to solve the governing equations. The obtained numerical results using realizable k-ε and β-PDF models show a good agreement with the experimental data. The results show that flame holder with greater lengths yield shorter ...
متن کاملImpacts of the Lower Stratosphere on the Development of Intense Tropical Cyclones
This study examines potential impacts of the lower stratosphere on the development and the inner-core structure of intense tropical cyclones (TCs). By initializing the Hurricane Weather Research and Forecasting (HWRF) model with different monthly averaged sounding profiles in the Northwestern Pacific and the North Atlantic basins, it is shown that the lower stratosphere layer (LSL) can impose a...

West Palm Beach (Florida), ISSN 0749-0208. The Saffir–Simpson scale is useful for evaluating maximum sustained hurricane winds and storm surge over open water in the prelandfall window, but it fails to accurately account for the observed i...
متن کاملImpacts of underwater turbulence on acoustical and optical signals and their linkage.
Acoustical and optical signal transmission underwater is of vital interest for both civilian and military applications. The range and signal to noise during the transmission, as a function of system and water optical properties, in terms of absorption and scattering, determines the effectiveness of deployed electro-optical (EO) technology. The impacts from turbulence have been demonstrated to a...
