“…At ICPSM the ECMWF wind data is part of the input information to the statistical storm surge forecast system (Canestrelli and Moretti, 2004;Canestrelli and Zampato, 2005;Bajo et al, 2007). The most recent version of the hydrodynamic model SHYFEM, operational at ICPSM (Bajo and Umgiesser, 2010), is driven by the corrected wind (see previous section).…”

“…They were progressively improved in time, from the simplest versions that only relied on the time series of the past, to the newest ones that take into account the predicted meteorological parameters (typically ECMWF pressure) and are "expert systems" capable of selecting a suitable set of coefficients, depending on the meteorological conditions. After 2002, hydrodynamic models were also operationally implemented at ICPSM, in particular a finite element model of the Mediterranean Sea, the SHYFEM model developed at ISMAR-CNR of Venice (Bajo et al, 2007), and a finite difference model of the Adriatic Sea, the HYPSE model developed at the University of Padua (Lionello et al, 2006). Both hydrodynamic models are forced by ECMWF pressure and wind fields.…”

Abstract. We describe the Henetus wave forecast system in the Adriatic Sea. Operational since 1996, the system is continuously upgraded, especially through the correction of the input ECMWF wind fields. As these fields are of progressively improved quality with the increasing resolution of the meteorological model, the correction needs to be correspondingly updated. This ensures a practically constant quality of the Henetus results in the Adriatic Sea since 1996. After suitable and extended validation of the quality of the results at different forecast ranges, the operational range has been recently extended to five days. The Henetus results are used also to improve the tidal forecast on the Venetian coasts and the Venice lagoon, particularly during the most severe events. Extensive statistics on the model performance are provided, both as analysis and forecast, by comparing the model results versus both satellite and buoy data.

“…The total water level extracted at the CNR Acqua Alta oceanographic platform (hereinafter referred to as Piattaforma; Cavaleri, 1999), situated 8 nautical miles off the Venice coast, is applied as BC to the lagoon inlets for the second run to provide the total sea level forecast in the main lagoon locations. In order to avoid a long spin-up period, the state vector of the dynamic system is saved, for each simulation, into a restart file (Bajo et al, 2007). This is then used as IC of the next-day forecast simulation (Table 1).…”

“…This latter aspect is particular relevant due to the national role of ISPRA in monitoring and forecasting hydrological and hydrographic parameters over the Venice Lagoon. Thus, the two IOPs are used to test the improvement, if any, in replacing the lower-resolution BOLAM configuration with the new higherresolution BOLAM-MOLOCH suite, and to assess the performance of the SIMM storm-surge forecasting component, namely the Shallow water HYdrodynamic Finite Element Model (SHYFEM, Umgiesser et al, 2004;Bajo et al, 2007;Zampato et al, 2007).…”

Abstract. High-resolution numerical models can be effective in monitoring and predicting natural hazards, especially when dealing with Mediterranean atmospheric and marine intense/severe events characterised by a wide range of interacting scales. The understanding of the key factors associated to these Mediterranean phenomena, and the usefulness of adopting high-resolution numerical models in their simulation, are among the aims of the international initiative HyMeX -HYdrological cycle in Mediterranean EXperiment. At the turn of 2013, two monitoring campaigns (SOPs -Special Observation Periods) were devoted to these issues. For this purpose, a new high-resolution BOlogna Limited Area Model-MOdello LOCale (BOLAM-MOLOCH) suite was implemented in the Institute for Environmental Protection and Research (ISPRA) hydro-meteo-marine forecasting system (SIMM -Sistema Idro-Meteo-Mare) as a possible alternative to the operational meteorological component based on the BOLAM model self-nested over two lower-resolution domains. The present paper provides an assessment of this new configuration of SIMM with respect to the operational one that was also used during the two SOPs. More in details, it investigates the forecast performance of these SIMM configurations during two of the Intense Observation Periods (IOPs) declared in the first SOP campaign. These IOPs were characterised by high precipitations and very intense and exceptional high waters over the northern Adriatic Sea (acqua alta). Concerning the meteorological component, the high-resolution BOLAM-MOLOCH forecasts are compared against the lower-resolution BOLAM forecasts over three areas -mostly corresponding to the Italian HyMeX hydrometeorological sites -using the rainfall observations collected in the HyMeX database. Three-month categorical scores are also calculated for the MOLOCH model. Despite the presence of a slight positive bias of the MOLOCH model, the results show that the precipitation forecast turns out to improve with increasing resolution. In both SIMM configurations, the sea storm surge component is based on the same version of the Shallow water HYdrodynamic Finite Element Model (SHYFEM). Hence, it is evaluated the impact of the meteorological forcing provided by the two adopted BO-LAM configurations on the SHYFEM forecasts for six tidegauge stations. A benchmark for this part of the study is given by the performance of the SHYFEM model forced by the ECMWF IFS forecast fields. For this component, both BOLAM-SHYFEM configurations clearly outperform the benchmark. The results are, however, strongly affected by the predictability of the weather systems associated to the IOPs, thus suggesting the opportunity to develop and test a time-lagged multi-model ensemble for the prediction of high storm surge events.

“…The coastal element of the system is composed of a set of finite element numerical models, including a three-dimensional hydrodynamic model (SHYFEM3D; see Umgiesser et al, 2004;Cucco and Umgiesser, 2006;Bajo et al, 2007;Bellafiore et al, 2008;Cucco et al, 2012) coupled with a phase averaging wind-wave model (SHYFEM3D-WWM; see Roland et al, 2009;Ferrarin et al, 2008) a Lagrangian trajectory module with a "weathering" module (FEMOIL, see Cucco et al, 2012) offline coupled with the SHYFEM3D-WWM. Such numerical models are aimed at operationally reproducing the hydrodynamics and transport processes in a restricted domain corresponding to the Bonifacio Strait area.…”

Abstract. An innovative forecasting system of the coastal marine circulation has been implemented in the Bonifacio Strait area, between Corsica and Sardinia, using a numerical approach to facilitate the rapid planning and coordination of remedial actions for oil spill emergencies at sea by local authorities. Downscaling and nesting techniques from regional to coastal scale and a 3-D hydrodynamic numerical model, coupled with a wind wave model, are the core of the integrated Bonifacio Strait system. Such a system is capable of predicting operationally the dispersion of hydrocarbon spills in the area, both in forward and backward mode, through an easy-to-use graphical user interface. A set of applications are described and discussed including both operational applications aimed at providing rapid responses to local oil spill emergences and managing applications aimed at mitigating the risk of oil spill impacts on the coast.
