RISTyphoon Morakot: Key Findings from the Journal TAO for Improving Prediction of Extreme Rains at Landfall
Publisher: American Meteorological Society
Numerical Simulation of Typhoon Gladys (1994) and Its Interaction with Taiwan Terrain Using the GFDL Hurricane Model
Publisher: American Meteorological Society
Abstract: Numerical integrations using the Geophysical Fluid Dynamics Laboratory (GFDL) hurricane model were performed to study the evolution of Typhoon Gladys (1994) and its interaction with the Taiwan terrain. Consistent with most ...
A Numerical Study of the Feedback Mechanisms of Hurricane–Environment Interaction on Hurricane Movement from the Potential Vorticity Perspective
Publisher: American Meteorological Society
Abstract: The interaction between a hurricane and its environment is studied by analysing the generation and influence of potential vorticity (PV) from the Geophysical Fluid Dynamics Laboratory hurricane model analysis system. Two ...
Typhoon-Position-Oriented Sensitivity Analysis. Part I: Theory and Verification
Publisher: American Meteorological Society
Abstract: new sensitivity analysis method is proposed for the ensemble prediction system in which a tropical cyclone (TC) position is taken as a metric. Sensitivity is defined as a slope of linear regression (or its approximation) ...
Secondary Eyewall Formation in an Idealized Tropical Cyclone Simulation: Balanced and Unbalanced Dynamics
Publisher: American Meteorological Society
Abstract: he secondary eyewall formation (SEF) in an idealized simulation of a tropical cyclone (TC) is examined from the perspective of both the balanced and unbalanced dynamics and through the tangential wind (Vt) budget analysis. ...
On the Processes Leading to the Rapid Intensification of Typhoon Megi (2010)
Publisher: American Meteorological Society
Abstract: he processes leading to the rapid intensification (RI) of Typhoon Megi (2010) are explored with a convection-permitting full-physics model and a sensitivity experiment using a different microphysical scheme. It is found ...
Interaction of a Baroclinic Vortex with Background Shear: Application to Hurricane Movement
Publisher: American Meteorological Society
Abstract: Most extant studies of tropical cyclone movement consider a barotropic vortex on a ? plane. However, observations have shown that real tropical cyclones are strongly baroclinic, with broad anticyclones aloft. Also, the ...
On Hurricane Outflow Structure
Publisher: American Meteorological Society
Abstract: Flow fields from the model of Wu and Emanuel are presented. It is demonstrated that the interaction of background shear with a uniform source of low potential vorticity air at the storm top can produce many of the observed ...
Potential Vorticity Diagnostics of Hurricane Movement. Part II: Tropical Storm Ana (1991) and Hurricane Andrew (1992)
Publisher: American Meteorological Society
Abstract: The validity of balance dynamics in the Tropics allows an exploration of the dynamics of hurricanes using the potential vorticity (PV) framework. Part I demonstrated the use of PV diagnostics in understanding the hurricane ...
An Observational Study of Environmental Influences on the Intensity Changes of Typhoons Flo (1990) and Gene (1990)
Publisher: American Meteorological Society
Abstract: The European Centre for Medium-Range Weather Forecasts Tropical Ocean?Global Atmosphere advanced analysis was used to study the mechanisms that affect the intensity of Typhoons Flo (1990) and Gene (1990). The outflow ...
