Environmental Interactions in the GFDL Hurricane Model for Hurricane Opal
Hurricane Opal (1995) crossed the Gulf of Mexico rapidly intensifying to a 130-kt storm, then fortunately weakening before landfall on the Florida panhandle. This intensification was underforecast by the National Hurricane Center. Forecast fields from the 1997 version of the Geophysical Fluid Dynamics Laboratory Hurricane Prediction System (GFDL model) for Hurricane Opal are used to diagnose th...
متن کاملHurricane Prediction with Python
The National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) is a global spectral model used for aviation weather forecast. It produces forecasts of wind speed and direction, temperature, humidity and precipitation out to 192 hr every 6 hours over the entire globe. The horizontal resolution in operational version of the GFS is about 25 km. Much longer integration of sim...
متن کاملOcean acoustic hurricane classification.
Theoretical and empirical evidence are combined to show that underwater acoustic sensing techniques may be valuable for measuring the wind speed and determining the destructive power of a hurricane. This is done by first developing a model for the acoustic intensity and mutual intensity in an ocean waveguide due to a hurricane and then determining the relationship between local wind speed and u...
متن کاملAdaptive Multigrid Hurricane Modeling
Adaptive multigrid techniques offer the potential of fast computation and high accuracy; they differ from conventional nested grid methods by making full use of the interplay between discretizations on the different grids. Their potential has been demonstrated in a multigrid barotropic hurricane track model (MUDBAR) developed by the PI, which runs ten to twenty times faster than a uniformresolu...
متن کاملMesovortices in Hurricane Isabel
n 12 September 2003, satellite images of Atlantic Hurricane Isabel astounded the tropical cyclone science community as a myriad of elaborate patterns revealed themselves within the clouds in Isabel’s eye. Patterns of convoluted clouds in hurricane eyes have been previously documented (Fletcher et al. 1961; Kossin et al. 2002; Montgomery et al. 2002), but Isabel showed us something new. As the f...
