  1. Italian Ministry for the Environment and Territory Continuation of Adricosm forecasting activities P. Oddo1, A. Coluccelli1, N. Pinardi2, M. Zavatarelli2 1-Istituto Nazionale di Geofisica e Vulcanologia (Gruppo Nazionale di Oceanografia Operativa) 2-Università di Bologna Progetto Requisite 12-13 Dicembre 2005 (Ancona) INGV UNIBO

  2. The AREG operational forecasting system

  3. The AREG operational forecasting system Data Assimilation of coastal CTD and open ocean XBT EOF have been computed for several Adriatic regions EOF have been calculated from model results and for the following seasons: Winter (January-April) Spring (May-June) Summer (July-October) Autumn (November-December) In regions 2,3,4,7 EOFs (T,S) from POM simulation In regions 5,6 EOF(T,S) from MFS

  4. The AREG operational forecasting system Data Assimilation of coastal CTD and open ocean XBT

  5. New high resolution model (under development) Same Code :POM Different grid hor.:5 to 2.2 km Different grid vert.: 21 to 41 sigma Different river run-off: reduced Croatian and Istrian Different advection scheme:Smol. to old POM scheme Different initial condition: Clim. POM to interannual OPA Different boundary condition:MFS PP(MOM) to STEP(OPA)

  10. Conclusions and Future work • AREG forecasting activities have been implemented successfully and development continues (Operational from April 2003). • Long term nesting of large shelf models seems to work without re-start and without model drift. • The model results show a strong inter-annual variability, confirmed also by observed data. • Data assimilation implemented for coastal CTD and open ocean XBTs • The AREG 2.2km 41 sigma layers has been implemented. • A preliminary comparison between model results has been carried out • Sensitivity experiments on vertical resolution • Improve the resolution of surface forcing (atmospheric and rivers run-off). • Support the activities for a high resolution coastal models.
