RISPerformance of the ECMWF Operational Analyses over the Tropical Indian Ocean
Publisher: American Meteorological Society
Abstract: The quality of the ECMWF operational analyses is evaluated against independent upper-air sounding data collected during the Joint Air?Sea Monsoon Interaction Experiment (JASMINE; April?May 1999) and the Indian Ocean ...
A Numerical Study of the 1996 Saguenay Flood Cyclone: Effect of Assimilation of Precipitation Data on Quantitative Precipitation Forecasts
Publisher: American Meteorological Society
Abstract: A one-dimensional variational (1DVAR) technique is applied to assimilate rain gauge precipitation data to extend the predictability of the Saguenay flood cyclone associated with a trough-merger event on 19?21 July 1996 in ...
A Numerical Study of a Mesoscale Convective System during TOGA COARE. Part I: Model Description and Verification
Publisher: American Meteorological Society
Abstract: A 16-h numerical simulation of the growing and mature stages of the 15 December 1992 Tropical Ocean Global Atmosphere Coupled Ocean?Atmosphere Response Experiment (TOGA COARE) mesoscale convective system (MCS) is performed ...
A Numerical Study of a Mesoscale Convective System during TOGA COARE. Part II: Organization
Publisher: American Meteorological Society
Abstract: In Part I, the authors presented a successful numerical simulation of the life cycle of a warm-pool mesoscale convective system (MCS) that occurred on 15 December 1992 during the Tropical Ocean Global Atmosphere Coupled ...
Probabilistic Weather Prediction with an Analog Ensemble
Publisher: American Meteorological Society
Abstract: his study explores an analog-based method to generate an ensemble [analog ensemble (AnEn)] in which the probability distribution of the future state of the atmosphere is estimated with a set of past observations that ...
An Evaluation of Analog-Based Postprocessing Methods across Several Variables and Forecast Models
Publisher: American Meteorological Society
Abstract: ecently, two analog-based postprocessing methods were demonstrated to reduce the systematic and random errors from Weather Research and Forecasting (WRF) Model predictions of 10-m wind speed over the central United States. ...
