Publisher: American Meteorological Society
Abstract: wo techniques for perturbing surface initial conditions in the regional ensemble system Aire Limitée Adaptation Dynamique Développement International-Limited Area Ensemble Forecasting (ALADIN-LAEF) are presented and ...
On the Impact of the Choice of Global Ensemble in Forcing a Regional Ensemble System
Publisher: American Meteorological Society
Abstract: t is quite common that in a regional ensemble system the large-scale initial condition (IC) perturbations and the lateral boundary condition (LBC) perturbations are taken from a global ensemble prediction system (EPS). The ...
Linking Stochasticity of Convection to Large-Scale Vertical Velocity to Improve Indian Summer Monsoon Simulation in the NCAR CAM5
Publisher: American Meteorological Society
Abstract: abstractThe Plant?Craig (PC) stochastic convective parameterization scheme is modified by linking the stochastic generation of convective clouds to the change of large-scale vertical pressure velocity at 500 hPa with time ...
Hybrid Dynamic Modeling and Analysis of High-Speed Thin-Rimmed Gears
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a hybrid dynamic model of high-speed thin-rimmed gears is developed. In this model, the translational and angular displacements (including the rigid and vibration displacements) with a total of six ...
