Publisher: American Meteorological Society
Untitled
Publisher: American Meteorological Society
Abstract: AbstractThrough a series of convection-permitting regional-scale ensembles based on the Weather Research and Forecasting (WRF) Model, this study investigates the predictability of multiscale weather and convectively coupled ...
Potentials in Improving Predictability of Multiscale Tropical Weather Systems Evaluated through Ensemble Assimilation of Simulated Satellite-Based Observations
Publisher: American Meteorological Society
Abstract: AbstractAs a follow-up of our recent paper on the practical and intrinsic predictability of multiscale tropical weather and equatorial waves, this study explores the potentials in improving the analysis and prediction of ...
Trends in Precipitable Water and Relative Humidity in China: 1979–2005
Publisher: American Meteorological Society
Abstract: nnual and seasonal trends of precipitable water (PW) and relative humidity (RH) at 850, 700, and 500 hPa are studied using the data from 106 radiosonde stations over China during the period 1979?2005. Analysis shows evidence ...
On the Selection of Localization Radius in Ensemble Filtering for Multiscale Quasigeostrophic Dynamics
Publisher: American Meteorological Society
Abstract: AbstractCovariance localization remedies sampling errors due to limited ensemble size in ensemble data assimilation. Previous studies suggest that the optimal localization radius depends on ensemble size, observation density ...

Dynamic Modeling of Compliant Mechanisms Based on the Pseudo-Rigid-Body Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the principle of dynamic equivalence, a new dynamic model of compliant mechanisms is developed using the pseudo-rigid-body model. The dynamic equation of general planar compliant mechanisms ...
Predictability of an Advection Fog Event over North China. Part I: Sensitivity to Initial Condition Differences
Publisher: American Meteorological Society
Abstract: he predictability of a dense advection fog event on 21 February 2007 over north China (NC) is investigated with ensemble simulations using the Weather Research and Forecasting Model (WRF). Members with the best and worst ...
