COSPAR-Training and Capacity Building Course on Earth Observation Understanding of the Water Cycle (Over Land and Ocean) María Eugenia Dillon Advanced atmospheric science’s student of the University of Buenos Aires (UBA), Argentine. Fellowship in a collaborative Research Project between the National Weather Service (SMN) and the Naval Hydrographic Service (SHN) of Argentina, sponsored by the Ministry of Defence.“Application of the latest developments in numerical models oriented to weather forecasting in the National Weather Service. Environmental vulnerability and socioeconomic impact studies”
Weather Research Forecasting - Advanced Research Weather Model (WRF-ARW) Version 3.1.1 Proccesed in a Hewleth Packard cluster, in the National Weather Service Suitable for use in a broad range of applications across scales, ranging from meters to thousands of kilometers, including: Idealized simulations Regional and global applications Parametrization research Data assimilation research Forecast research Coupled-model applications (http://www.mmm.ucar.edu/wrf/users)
Since February 2010… Daily experimental information available for the forecasters Adjacent maritime zones 10 meters wind Regional 2m temperature and relative humidity We are working on new products to improve our service to forecasters
Results verification 2m temperature at 9 argentine meteorological stations, for Southern Hemisfere Autumn of 2010 Utilizing the basic statistical BIAS and RMSE, and analysing time series. We also made a comparisson between WRF results and ETA/SMN model results. We obtained an improvement in the T2m by changing the resolution of the topography.
WRF/CTRL WRF/CTRL WRF/CPTEC WRF/CPTEC WRF/CPTEC gcm-3 gcm-3 gcm-3 gcm-3 Sensitivity of the model to different lower boundary conditions, focused on the La Plata Basin Comparisson between initialization of soil moisture (0-10cm) with GFS and with CPTEC model. Partial verification using remote sensing data of the passive radiometer AMSR-E (on board the AQUA satellite). The derived soil moisture field corresponds to 1cm only.
Implications in the precipitation There is a displacement to the east of the local maximum of precipitation in the WRF-CPTEC.
Future Research… Experiments to compare the initialization with GFS and CPTEC, using other case studies, in order to reach stronger conclusions. Experiments with AMSR-E soil moisture data assimilation in the WRF-ARW model Exploration of ASCAT soil moisture data and also other remote sensing products, as this type of source is particularly important in the South American region, mainly in Argentina, due to the lack of enough meteorological observing stations.
