DHI SOLUTION

THE MODELLING SYSTEM The Mediterranean Model (MWM) database is the result of implementing a modelling chain that combines two state-of-the-art models for atmospheric modelling. The first— Weather Research and Forecasting (WRF)-Advanced Research of WRF (WRF-ARW)—is a widely used non- hydrostatic open source model and the second—MIKE 21 SW—is a wave model developed by DHI and widely used in thousands of offshore and coastal applications worldwide. data on a flexible mesh of the Mediterranean Sea Several technical and scientific challenges have been addressed in the production of the database: Mediterranean Sea)

 the computational effort for simulating a long-term analysis  line series to be used as boundary conditions of local scale at high resolution, which required the use of a powerful High wave models

Performance Computing (HPC) infrastructure  ordinary and extreme wind and wave conditions

 the huge storage capacity needed to save both wind-wave  statistical processing of data parameters and wave energy spectra  specific products and analyses at higher resolution upon  the implementation of complex and robust procedures for request model validation, data handling and simulation control BENEFITS OF THE MWM THE MWM DATABASE OFFERS YOU: Compared to other available hindcast datasets, MWM has a number of features which makes it the main reference in the Mediterranean Sea, in particular:  the high resolution (up to 0.03° for the wave model, never lower than 0.1° for both wind and wave models) allows a proper simulation of local dynamics

 the specific calibration based on measured data, both for ordinary and extreme conditions

 the validation against satellite data over the entire Mediterranean Sea, through robust and innovative procedures

 state-of-the-art numerical models, used in thousands of applications worldwide

 the technical support from our team of experts

 readily available data Probability Scatter Plot of Hs (Significant ) -  Dedicated studies and data processing upon request comparison of model data vs satellite data (ENVISAT)

MORE THAN JUST HISTORICAL DATA  35 years of historical data (1980-2014) In addition to the historical hindcast database, a forecast  wind and wave parameters (wind speed and direction, wave service for wind and wave in the Mediterranean Sea is also height, direction and periods) available. The system can be activated upon request and  spectral data (available on a 0.1° grid for the whole configured according to specific requirements.

ABOUT DHI AND HYMOLAB DHI are the first people you should call when you have a tough challenge to solve in a water environment. In the world of water, our knowledge is second-to-none, and we strive to make it globally accessible to clients and partners. So whether you need to save water, share it fairly, im- prove its quality, quantify its impact or manage its flow, we can help. Our knowledge, combined with our team’s expertise and the power of our technology, hold the key to unlocking the right solution. HyMOLab (Hydrodynamics and Met- Laboratory) is a structure of the Department of Engineering and Architecture of the University of Trieste (Italy). The HyMOLab group of researchers has operated for years within the fields of naval and Metocean engineering, with self- owned software and High Performance Computing facilities (HPSC).
