There are four main areas of benefits covered by the service: maritime safety, coastal and marine environment, marine resources, and weather seasonal forecasting and climate activities. CMEMS is based on a production structure covering two layers: Processing of space and in-situ observations and delivery of derived products: this is achieved through Thematic Assembly Centres (TACs) organized according to consistent parameters – or sets of parameters. CMEMS include eight TACs mainly handling space observations (Sea Level, Ocean Colour, Sea Surface Temperature, Sea Ice, Winds, Waves, and Multi-Observation Integration), and one TAC dedicated to In-Situ observations. Processing of models, for forecasts, hind-cast and reanalyses, fed by products derived from space and in-situ observations (to be provided by the TACs): these tasks are achieved by Monitoring and Forecasting Centres (MFCs), structured according to regional domains (6 European regional seas) and global ocean. The service provides, to several thousands of users, pioneering solutions, operational and scientifically assessed, to monitor the global ocean with a focus on the European seas. In agreement with the Delegated Regulation on Copernicus data and information policy, the products delivered by CMEMS are open and free of charge, and compliant with European regulations, such as INSPIRE. The products are accessible through a European one-stop-shop, the CMEMS web-portal, which includes a structured information catalogue monitored to ensure that it complies with its operational obligations to users. Earth observation data from In-situ components provide crucial and unique global ocean information along the water column. The provision of these data, used by CMEMS to derive more elaborated products, strongly depends on the proper specification of requirements, which have to be updated regularly to ensure the evolution of the service in response to user needs. CMEMS REQUIREMENTS FOR IN SITU OBSERVATIONS 5 THE ROLE OF IN-SITU OBSERVATIONS AND ITS ORGANIZATION IN CMEMS In-situ data are of paramount importance for CMEMS as they can provide information of the ocean interior which cannot be observed from space. Delivery of CMEMS products strongly relies on timely provision of in-situ observations; global to regional scale observations are required by MFCs for model testing and calibration, and for assimilation and validation in operational phase. In addition in-situ observations are used by CMEMS TACs to elaborate and validate high level data products. Figure 1: CMEMS marine sea-borne infrastructure. CMEMS REQUIREMENTS FOR IN SITU OBSERVATIONS 6 Operational oceanography relies on the observation of a well-defined number of variables (Essential Ocean Variables or EOVs) which have to be provided in a timely and sustained manner with appropriate sampling. CMEMS has set up a dedicated unit the “INS-TAC”, focused on collecting in-situ data from data providers (national and international networks), carrying out quality control in a homogeneous manner, and distributing them in near real time. Today the INS-TAC is one of the major aggregators of in-situ observation at global level, with a structure developed in coherence with other components of the pan European data management landscape such as SeaDataNet and EMODnet (see Figure 1). The INS- TAC is not only directly gathering observations but collaborates closely with the institutes operating the networks both at global scale (Argo, OceanSITES, DBCP, EGO, etc.) and at European scale through the EuroGOOS Regional Ocean Observing Systems (Arctic ROOS, BOOS, NOOS, IBI-ROOS, MOONGOOS and Black Sea GOOS). The main types of In-Situ observing systems aggregated by INS-TAC include all the platforms identified in the initial Strategic Development Plan [1], and many others, made available over the years, as soon as their quality was deemed appropriate to meet service requirements; they comprise: Drifting Argo Floats for the measurement of temperature and salinity profiles to ~2000m and, by tracking them, mean subsurface currents. In addition the latest model BGC-Argo allows measurements of biogeochemical properties of the oceans. Research vessels which deliver complete suites of multidisciplinary parameters from the surface

  • The Use of a Vortex Insertion Technique to Simulate the Extratropical Transition of Hurricane Michael (2000)
    480 WEATHER AND FORECASTING VOLUME 22 The Use of a Vortex Insertion Technique to Simulate the Extratropical Transition of Hurricane Michael (2000) CHRISTOPHER T. FOGARTY Canadian Hurricane Centre, Dartmouth, Nova Scotia, Canada RICHARD J. GREATBATCH AND HAROLD RITCHIE Department of Oceanography, Dalhousie University, Halifax, Nova Scotia, Canada (Manuscript received 27 May 2005, in final form 30 October 2006) ABSTRACT On 19 October 2000, Hurricane Michael merged with an approaching baroclinic trough over the western North Atlantic Ocean south of Nova Scotia. As the hurricane moved over cooler sea surface temperatures (SSTs; less than 25°C), it intensified to category-2 intensity on the Saffir–Simpson hurricane scale [maxi- mum sustained wind speeds of 44 m sϪ1 (85 kt)] while tapping energy from the baroclinic environment. The large “hybrid” storm made landfall on the south coast of Newfoundland with maximum sustained winds of 39 m sϪ1 (75 kt) causing moderate damage to coastal communities east of landfall. Hurricane Michael presented significant challenges to weather forecasters. The fundamental issue was determining which of two cyclones (a newly formed baroclinic low south of Nova Scotia or the hurricane) would become the dominant circulation center during the early stages of the extratropical transition (ET) process. Second, it was difficult to predict the intensity of the storm at landfall owing to competing factors: 1) decreasing SSTs conducive to weakening and 2) the approaching negatively tilted upper-level trough, favoring intensifica- tion. Numerical hindcast simulations using the limited-area Mesoscale Compressible Community model with synthetic vortex insertion (cyclone bogus) prior to the ET of Hurricane Michael led to a more realistic evolution of wind and pressure compared to running the model without vortex insertion.
