Application of the WRF-LETKF Data Assimilation System over Southern South America: Sensitivity to Model Physics
(American Meteorological Society, 2016-02-10)Resumen
Improving the initial conditions of short-range numerical weather prediction (NWP) models is one of the main goals of the meteorological community. Development of data assimilation and ensemble forecast systems is essential ... -
Impact of enriched analyses on regional numerical forecasts over southeastern South America during SALLJEX
(Revista Brasileira de Meteorologia, 2014)Resumen
During the warm season 2002-2003, the South American Low-Level Jet Experiment (SALLJEX) was carried out in southeastern South America. Taking advantage of the unique database collected in the region, a set of analyses is ... -
Volcanic ash forecast using ensemble-based data assimilation: an ensemble transform Kalman filter coupled with the FALL3D-7.2 model (ETKF–FALL3D version 1.0)
(Geoscientific Model Development, 2020-01)Resumen
Quantitative volcanic ash cloud forecasts are prone to uncertainties coming from the source term quantification (e.g., the eruption strength or vertical distribution of the emitted particles), with consequent implications ...
