Size and Structure of Dry and Moist Reversible Tropical Cyclones
Publisher: American Meteorological Society
Abstract: The size and structure of tropical cyclones (TCs) are investigated using idealized numerical simulations. Three simulations are conducted: a pure dry TC (DRY), a moist reversible TC (REV) with fallout of hydrometeors in ...
Madden–Julian Oscillations Seen in the Upper-Troposphere Vorticity Field: Interactions with Rossby Wave Trains
Publisher: American Meteorological Society
Abstract: AbstractThe vorticity variability associated with the Madden?Julian oscillation (MJO) is examined. The analysis is focused on the 150-hPa pressure level, because a clear dipolar-vortex signal, reminiscent of the theoretically ...
Potential Role of Irreversible Moist Processes in Modulating Tropical Cyclone Surface Wind Structure
Publisher: American Meteorological Society
A New Bulk Microphysical Scheme That Includes Riming Intensity and Temperature-Dependent Ice Characteristics
Publisher: American Meteorological Society
Abstract: A new bulk microphysical parameterization (BMP) scheme is presented that includes a diagnosed riming intensity and its impact on ice characteristics. As a result, the new scheme represents a continuous spectrum from pristine ...
The 4–5 December 2001 IMPROVE-2 Event: Observed Microphysics and Comparisons with the Weather Research and Forecasting Model
Publisher: American Meteorological Society
Abstract: This paper highlights the observed and simulated microphysical evolution of a moderate orographic rainfall event over the central Oregon Cascade Range during 4?5 December 2001 of the Second Improvement of Microphysical ...
How Much Does the Upward Advection of the Supergradient Component of Boundary Layer Wind Contribute to Tropical Cyclone Intensification and Maximum Intensity?
Publisher: American Meteorological Society
Abstract: Although the development of supergradient winds is well understood, the importance of supergradient winds in tropical cyclone (TC) intensification is still under debate. One view is that the spinup of the eyewall occurs ...
Implementation and Evaluation of a Double-Plume Convective Parameterization in NCAR CAM5
Publisher: American Meteorological Society
Parameterization of Riming Intensity and Its Impact on Ice Fall Speed Using ARM Data
Publisher: American Meteorological Society
Abstract: Riming within mixed-phase clouds can have a large impact on the prediction of clouds and precipitation within weather and climate models. The increase of ice particle fall speed due to riming has not been considered in ...
Orographic Modification of Convection and Flow Kinematics by the Oregon Coast Range and Cascades during IMPROVE-2
Publisher: American Meteorological Society
Abstract: This paper describes the kinematic and precipitation evolution accompanying the passage of a cold baroclinic trough over the Central Oregon Coast Range and Cascades during 4?5 December 2001 of the second Improvement of ...
