Dynamics and Structure of Mesoscale Error Covariance of a Winter Cyclone Estimated through Short-Range Ensemble Forecasts
Publisher: American Meteorological Society
Abstract: Several sets of short-range mesoscale ensemble forecasts generated with different types of initial perturbations are used in this study to investigate the dynamics and structure of mesoscale error covariance in an intensive ...
Generation of Mesoscale Gravity Waves in Upper-Tropospheric Jet–Front Systems
Publisher: American Meteorological Society
Abstract: Multiply nested mesoscale numerical simulations with horizontal resolution up to 3.3 km are performed to study the generation of mesoscale gravity waves during the life cycle of idealized baroclinic jet?front systems. ...
Evolution of Dynamic and Thermodynamic Structures before and during Rapid Intensification of Tropical Cyclones: Sensitivity to Vertical Wind Shear
Publisher: American Meteorological Society
Abstract: AbstractThis study explores the spatial and temporal changes in tropical cyclone (TC) thermodynamic and dynamic structures before, near, and during rapid intensification (RI) under different vertical wind shear conditions ...
On the Role of Surface Fluxes and WISHE in Tropical Cyclone Intensification
Publisher: American Meteorological Society
Abstract: he authors show that the feedback between surface wind and surface enthalpy flux is an important influence on tropical cyclone evolution, even though, as with at least some classical instability mechanisms, such a feedback ...
On the Predictability and Error Sources of Tropical Cyclone Intensity Forecasts
Publisher: American Meteorological Society
Abstract: he skill of tropical cyclone intensity forecasts has improved slowly since such forecasts became routine, even though track forecast skill has increased markedly over the same period. In deciding whether or how best to ...
Contribution of Tropical Waves to the Formation of Supertyphoon Megi (2010)
Publisher: American Meteorological Society
Abstract: hrough observational analysis and numerical simulations, this study examines the roles of the Madden?Julian oscillation (MJO) and tropical waves in the three-stage formation of Supertyphoon Megi (2010) including 1) convective ...
Impacts of the Diurnal Radiation Cycle on the Formation, Intensity, and Structure of Hurricane Edouard (2014)
Publisher: American Meteorological Society
Abstract: his work examines the impacts of the diurnally varying radiation cycle on the formation, intensity, structure, and track of Hurricane Edouard (2014) at different stages of its life cycle through convection-permitting ...
Source of Gravity Waves within a Vortex-Dipole Jet Revealed by a Linear Model
Publisher: American Meteorological Society
Abstract: This study develops a linear numerical model to address the source mechanism of the gravity waves generated within a vortex dipole simulated in a fully nonlinear nonhydrostatic mesoscale model. The background flow for this ...
Evolution of Multiscale Vortices in the Development of Hurricane Dolly (2008)
Publisher: American Meteorological Society
Abstract: As a follow-up to a previously published article on the initial development and genesis of Hurricane Dolly (2008), this study further examines the evolution of, and interactions among, multiscale vortices ranging from the ...
