RISExploring the Diabatic Role of Ice Microphysical Processes in Two North Atlantic Summer Cyclones
Publisher: American Meteorological Society
Abstract: umerical simulations are performed with the Weather Research and Forecasting Model to elucidate the diabatic effects of ice phase microphysical processes on the dynamics of two slow-moving summer cyclones that affected the ...
Observations of the Origin and Distribution of Ice in Cold, Warm, and Occluded Frontal Systems during the DIAMET Campaign
Publisher: American Meteorological Society
Abstract: hree case studies in frontal clouds from the Diabatic Influences on Mesoscale Structures in Extratropical Storms (DIAMET) project are described to understand the microphysical development of the mixed phase regions of these ...
The Physical Properties of the Atmosphere in the New Hadley Centre Global Environmental Model (HadGEM1). Part I: Model Description and Global Climatology
Publisher: American Meteorological Society
Abstract: The atmospheric component of the new Hadley Centre Global Environmental Model (HadGEM1) is described and an assessment of its mean climatology presented. HadGEM1 includes substantially improved representations of physical ...
Diabatic Heating and Cooling Rates Derived from In Situ Microphysics Measurements: A Case Study of a Wintertime U.K. Cold Front
Publisher: American Meteorological Society
Abstract: n situ measurements associated with the passage of a kata cold front over the United Kingdom on 29 November 2011 are used to initialize a Lagrangian parcel model for the purpose of calculating rates of diabatic heating and ...
Secondary Ice Production: Current State of the Science and Recommendations for the Future
Publisher: American Meteorological Society
Abstract: easured ice crystal concentrations in natural clouds at modest supercooling (temperature ~>?10°C) are often orders of magnitude greater than the number concentration of primary ice nucleating particles. Therefore, it has ...
Cloud Banding and Winds in Intense European Cyclones: Results from the DIAMET Project
Publisher: American Meteorological Society
Abstract: he Diabatic Influences on Mesoscale Structures in Extratropical Storms (DIAMET) project aims to improve forecasts of high-impact weather in extratropical cyclones through field measurements, high-resolution numerical ...
