RISPrediction and Diagnosis of Tropical Cyclone Formation in an NWP System. Part I: The Critical Role of Vortex Enhancement in Deep Convection
Publisher: American Meteorological Society
Abstract: This is the first of a three-part investigation into tropical cyclone (TC) genesis in the Australian Bureau of Meteorology?s Tropical Cyclone Limited Area Prediction System (TC-LAPS), an operational numerical weather ...
Genesis of Pre–Hurricane Felix (2007). Part I: The Role of the Easterly Wave Critical Layer
Publisher: American Meteorological Society
Abstract: The formation of pre?Hurricane Felix (2007) in a tropical easterly wave is examined in a two-part study using the Weather Research and Forecasting (WRF) model with a high-resolution nested grid configuration that permits ...
Prediction and Diagnosis of Tropical Cyclone Formation in an NWP System. Part III: Diagnosis of Developing and Nondeveloping Storms
Publisher: American Meteorological Society
Abstract: This is the third of a three-part investigation into tropical cyclone (TC) genesis in the Australian Bureau of Meteorology?s Tropical Cyclone Limited Area Prediction System (TC-LAPS), an operational numerical weather ...
Numerical Simulations of the Formation of Hurricane Gabrielle (2001)
Publisher: American Meteorological Society
Abstract: This study examines the formation of Hurricane Gabrielle (2001), focusing on whether an initial disturbance and vertical wind shear were favorable for development. This examination is performed by running numerical experiments ...
Genesis of Pre–Hurricane Felix (2007). Part II: Warm Core Formation, Precipitation Evolution, and Predictability
Publisher: American Meteorological Society
Abstract: This is the second of a two-part study examining the simulated formation of Atlantic Hurricane Felix (2007) in a cloud-representing framework. Here several open issues are addressed concerning the formation of the storm?s ...
Compressor Efficiency Variation With Rotor Tip Gap From Vanishing to Large Clearance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compressor efficiency variation with rotor tip gap is assessed using numerical simulations on an embedded stage representative of that in a large industrial gas turbine with Reynolds number ∼ 2 أ— 106 to 7 أ— 106. ...
Prediction and Diagnosis of Tropical Cyclone Formation in an NWP System. Part II: A Diagnosis of Tropical Cyclone Chris Formation
Publisher: American Meteorological Society
Abstract: This is the second of a three-part investigation into tropical cyclone (TC) genesis in the Australian Bureau of Meteorology?s Tropical Cyclone Limited Area Prediction System (TC-LAPS). The primary TC-LAPS vortex enhancement ...
A Vortical Hot Tower Route to Tropical Cyclogenesis
Publisher: American Meteorological Society
Abstract: A nonhydrostatic cloud model is used to examine the thermomechanics of tropical cyclogenesis under realistic meteorological conditions. Observations motivate the focus on the problem of how a midtropospheric cyclonic vortex, ...
Impact of Physics Representations in the HWRFX on Simulated Hurricane Structure and Pressure–Wind Relationships
Publisher: American Meteorological Society
Abstract: series of idealized experiments with the NOAA Experimental Hurricane Weather Research and Forecasting Model (HWRFX) are performed to examine the sensitivity of idealized tropical cyclone (TC) intensification to various ...
