RISSensitivity Testing of Extratropical Transitions Using Potential Vorticity Inversions to Modify Initial Conditions: Hurricane Earl Case Study
Publisher: American Meteorological Society
Abstract: This study uses the Mesoscale Compressible Community model to simulate the extratropical transition and reintensification of Hurricane Earl (1998) for the purposes of testing sensitivity to modification of the model's ...
The Impact of Tropical Remnants on Extratropical Cyclogenesis: Case Study of Hurricanes Danielle and Earl (1998)
Publisher: American Meteorological Society
Abstract: The importance of remnant tropical cyclone (TC) circulation and moisture structures is investigated for a simultaneous extratropical transition (ET) event involving ex-Hurricanes Danielle and Earl (September 1998). Although ...

Moist Component Potential Vorticity
Publisher: American Meteorological Society
Abstract: The role that atmospheric water, in both its liquid and vapor phases, plays in cyclogenesis is difficult to determine because of the complex interactions between dynamic and thermodynamic forcings. From a potential vorticity ...
Sensitivity of Idealized Moist Baroclinic Waves to Environmental Temperature and Moisture Content
Publisher: American Meteorological Society
Abstract: AbstractIdealized simulations are used to examine the sensitivity of moist baroclinic wave growth to environmental temperature and moisture content. With relative humidity held fixed, the surface temperature at 45°N, denoted ...
Energy and Water Cycles in a High-Latitude, North-Flowing River System
Publisher: American Meteorological Society
Abstract: The MacKenzie Global Energy and Water Cycle Experiment (GEWEX) Study, Phase 1, seeks to improve understanding of energy and water cycling in the Mackenzie River basin (MRB) and to initiate and test atmospheric, hydrologic, ...
