RISElectrification and lightning in idealized simulations of a hurricane-like vortex subject to wind shear and sea surface temperature cooling.
Publisher: American Meteorological Society
Abstract: elationships between intensity fluctuations, cloud microphysics, lightning variations and electrical structure within idealized tropical cyclones are investigated with the cloud-resolving Collaborative Model for Multiscale ...
High-Resolution Simulation of the Electrification and Lightning of Hurricane Rita during the Period of Rapid Intensification
Publisher: American Meteorological Society
Abstract: In this paper, a high-resolution simulation establishing relationships between lightning and eyewall convection during the rapid intensification phase of Rita will be highlighted. The simulation is an attempt to relate ...
Relationships between Southeast Australian Temperature Anomalies and Large-Scale Climate Drivers
Publisher: American Meteorological Society
Abstract: ver the past century, particularly after the 1960s, observations of mean maximum temperatures reveal an increasing trend over the southeastern quadrant of the Australian continent. Correlation analysis of seasonally averaged ...
Links between Central West Western Australian Rainfall Variability and Large-Scale Climate Drivers
Publisher: American Meteorological Society
Abstract: ver the past century, and especially after the 1970s, rainfall observations show an increase (decrease) of the wet summer (winter) season rainfall over northwest (southwest) Western Australia. The rainfall in central west ...
Relationships between Electrification and Storm-Scale Properties Based on Idealized Simulations of an Intensifying Hurricane-Like Vortex
Publisher: American Meteorological Society
Abstract: AbstractThis study investigates relationships between storm-scale properties and the electrification and lightning of two simulations of an intensifying idealized tropical cyclone (TC) using the cloud-resolving Collaborative ...
Microphysics of Maritime Tropical Convective Updrafts at Temperatures from −20° to −60°
Publisher: American Meteorological Society
Abstract: Anvils produced by vigorous tropical convection contribute significantly to the earth?s radiation balance, and their radiative properties depend largely on the concentrations and sizes of the ice particles that form them. ...
Evolution of GLM-Observed Total Lightning in Hurricane Maria (2017) during the Period of Maximum Intensity
Publisher: American Meteorological Society
Abstract: AbstractTotal lightning data obtained from the Geostationary Lightning Mapper (GLM) were analyzed to present a first glimpse of relationships with intensity variations and convective evolution in Hurricane Maria (2017). ...
Tropical Oceanic Hot Towers: Need They Be Undilute to Transport Energy from the Boundary Layer to the Upper Troposphere Effectively? An Answer Based on Trajectory Analysis of a Simulation of a TOGA COARE Convective System
Publisher: American Meteorological Society
Abstract: his paper addresses questions resulting from the authors? earlier simulation of the 9 February 1993 Tropical Ocean Global Atmosphere Coupled Ocean?Atmosphere Research Experiment (TOGA COARE) squall line, which used updraft ...
On How Hot Towers Fuel the Hadley Cell: An Observational and Modeling Study of Line-Organized Convection in the Equatorial Trough from TOGA COARE
Publisher: American Meteorological Society
Abstract: An airflow trajectory analysis was carried out based on an idealized numerical simulation of the nocturnal 9 February 1993 equatorial oceanic squall line observed over the Tropical Ocean and Global Atmosphere Coupled ...
Determining Key Model Parameters of Rapidly Intensifying Hurricane Guillermo (1997) Using the Ensemble Kalman Filter
Publisher: American Meteorological Society
Abstract: n this work the authors determine key model parameters for rapidly intensifying Hurricane Guillermo (1997) using the ensemble Kalman filter (EnKF). The approach is to utilize the EnKF as a tool only to estimate the parameter ...
