Abstract: The computation of hydrometeor sedimentation in one-moment, two-moment, and three-moment bulk microphysics parameterizations is examined in the context of a 1D model, with no other microphysical processes active. The ...

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 ...

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 ...

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 ...

Abstract: This is the second in a series of papers examining the behavior of the Milbrandt?Yau multimoment bulk microphysics scheme for the simulation of the 13?14 December 2001 case of orographically enhanced precipitation observed ...

Abstract: eep convection is one of various complex processes driving the evolution of tropical cyclones (TCs). The scales associated with deep convection are too small to be resolved by global NWP models. In the deep convection ...

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 ...

Abstract: The 2010 Winter Olympic and Paralympic Games took place in Vancouver, British Columbia, Canada, on 12?28 February and 12?21 March 2010, respectively. Weather forecasting presents specific challenges at the various Olympic ...
