RISThe Formation of a Cooling-induced Mesovortex in the Trailing Stratiform Region of a Midlatitude Squall Line
Publisher: American Meteorological Society
Abstract: There have been some ambiguities in recent observational studies as to whether midlevel mesovortices are induced by latent heating or cooling, and develop in the descending or ascending portion of mesoscale convective ...
Enhancement of Extratropical Cyclogenesis by a Mesoscale Convective System
Publisher: American Meteorological Society
Abstract: Considerable progress has been made in the past decades on understanding the life cycle of rapidly deepening winter cyclones. However, little attention has been paid to the role that mesoscale convective systems (MCSs) ...
A High-Resolution Model of the Planetary Boundary Layer—Sensitivity Tests and Comparisons with SESAME-79 Data
Publisher: American Meteorological Society
Abstract: A high-resolution, one-dimensional, moist planetary boundary layer (PBL) model is developed following Blackadar, and verified using the 10 April 1979 SESAME data set. The model consists of two modules to predict the ...
Genesis of Typhoon Chanchu (2006) from a Westerly Wind Burst Associated with the MJO. Part II: Roles of Deep Convection in Tropical Transition
Publisher: American Meteorological Society
Abstract: n this study, the life cycles of a series of four major mesoscale convective systems (MCSs) during genesis and their roles in transforming a vertically tilted vortex associated with a westerly wind burst (hereafter the WWB ...
Genesis of Typhoon Chanchu (2006) from a Westerly Wind Burst Associated with the MJO. Part I: Evolution of a Vertically Tilted Precursor Vortex
Publisher: American Meteorological Society
Abstract: Although previous studies have shown the relationship between the Madden?Julian oscillation (MJO) and tropical cyclogenesis (TCG), many scale-interactive processes leading to TCG still remain mysterious. In this study, the ...
Numerical Simulation of Hurricane Bonnie (1998). Part III: Energetics
Publisher: American Meteorological Society
Abstract: Despite considerable research on tropical cyclones (TCs), few studies have been performed to examine inner-core energy conversions because of the lack of high-resolution data. In this study, the TC energetic characteristics ...
On the Rapid Intensification of Hurricane Wilma (2005). Part II: Convective Bursts and the Upper-Level Warm Core
Publisher: American Meteorological Society
Abstract: revious studies have focused mostly on the roles of environmental factors in the rapid intensification (RI) of tropical cyclones (TCs) because of the lack of high-resolution data in inner-core regions. In this study, the ...
Numerical Simulation of an Intense Squall Line during 10–11 June 1985 PRE-STORM. Part II: Rear Inflow, Surface Pressure Perturbations and Stratiform Precipitation
Publisher: American Meteorological Society
Abstract: An intense rear-inflow jet, surface pressure perturbations, and stratiform precipitation associated with a squall line during 10?11 June 1985 are examined using a three-dimensional mesoscale nested-grid model. It is found ...
Oceanic Cyclogenesis as Induced by a Mesoscale Convective System Moving Offshore. Part II: Genesis and Thermodynamic Transformation
Publisher: American Meteorological Society
Abstract: The genesis of intense cyclonic vorticity in the boundary layer and the transformation of a low-level cold pool to a warm-core anomaly associated with the long-lived mesoscale convective systems (MCSs), which produced the ...
A Numerical Study of the Along-Line Variability of a Frontal Squall Line during PRE-STORM
Publisher: American Meteorological Society
Abstract: Despite considerable progress in the understanding of two-dimensional structures of squall lines, little attention has been paid to the along-line variability of these convective systems. In this study, the roles of meso- ...
