RISThe Roles of Surface-Observation Ensemble Assimilation and Model Complexity for Nowcasting of PBL Profiles: A Factor Separation Analysis
Publisher: American Meteorological Society
Abstract: Recent results showed the ability of surface-observation assimilation with a single-column model (SCM) and an ensemble filter (EF) to skillfully estimate the vertical structure of the PBL when only climatological information ...
PBL State Estimation with Surface Observations, a Column Model, and an Ensemble Filter
Publisher: American Meteorological Society
Abstract: Following recent results showing the potential for using surface observations of temperature, water vapor mixing ratio, and winds to determine PBL profiles, this paper reports on experiments with real observations. A 1D ...
Impact of Flow Dependence, Column Covariance, and Forecast Model Type on Surface-Observation Assimilation for Probabilistic PBL Profile Nowcasts
Publisher: American Meteorological Society
Abstract: probabilistic verification and factor-separation analysis (FSA) elucidate skillful nowcasts of planetary boundary layer (PBL) temperature, moisture, and wind profiles with a single-column model (SCM) and ensemble filter ...
A Reanalysis System for the Generation of Mesoscale Climatographies
Publisher: American Meteorological Society
Abstract: The use of a mesoscale model?based four-dimensional data assimilation (FDDA) system for generating mesoscale climatographies is demonstrated. This dynamical downscaling method utilizes the fifth-generation Pennsylvania ...
