Coupled physical and biochemical data driven simulations of Black Sea in spring-summer: real-time forecast and data assimilation

Besiktepe, ST
Data driven simulations in the Black Sea based upon observations during May-June 2001 in the SW part of the basin and coupled 3D physical and biochemical models have been carried out. The model was initialised with the data obtained during 22-28 May, 2001 and ran until 15 June, 2001. The data obtained in the second leg during 12-18 June, 2001 was assimilated into the model. At the time of the assimilation, the model forecast and the data were also compared. Quantitative and qualitative comparisons of the coupled model fields with data show that the predictive capability of the model was about one week.


Modulation of frontogenetic plankton production along a meandering jet by zonal wind forcing: An application to the Alboran Sea
Oguz, Temel; Mourre, Baptiste; Tintore, Joaquin (2017-08-01)
We present a coupled physical-biological modeling study to elucidate the changes in ageostrophic frontal dynamics and the frontogenetic plankton production characteristics of a meandering jet under the impacts of successive westerly/easterly wind events combined with seasonal variations in the upstream transport and buoyancy flux characteristics of the jet, using a case study for the Alboran Sea (Western Mediterranean). Their nonlinear coupling is shown to result in different forms of physical and biologica...
Water-mass properties and circulation on the west Antarctic Peninsula Continental Shelf in Austral Fall and Winter 2001
Klinck, JM; Hofmann, EE; Beardsley, RC; Salihoğlu, Barış; Howard, S (2004-01-01)
Hydrographic measurements made during the US Southern Ocean Global Ocean Ecosystem Dynamics cruises, which took place from April to June and July to September 2001, provide a description of changes in water-mass distributions and circulation patterns in the Marguerite Bay region of the west Antarctic Peninsula continental shelf that result from seasonal variability and offshore forcing by the southern boundary of the Antarctic Circumpolar Current (ACC). The primary seasonal change in water-mass properties i...
Coastal deep ocean interactions in the Black Sea and their ecological/environmental impacts
Sur, HI; Ozsoy, E; Ilyin, YP; Unluata, U (1996-02-01)
Satellite (CZCS, AVHRR) and in-situ (CTD, ADCP) data are utilized to characterize the impact of meso-scale motions and boundary currents on transport and productivity along the wide Western Black Sea Shelf.
Aeroservoelastic Modelling and Analysis of a Missile Control Surface with a Nonlinear Electromechanical Actuator
Mehmet Ozan, Nalcı; Kayran, Altan (null; 2014-06-16)
In this study, aeroservoelastic modeling and analysis of a missile control surface which is operated and controlled by a power limited, nonlinear electromechanical actuator is performed. Linear models of the control fin structure and aerodynamics together with the nonlinear servo-actuation system are built and integrated. The resulting aeroservoelastic system is analyzed both in time and frequency domain. Structural model of the control fin is based on the finite element model of the fin. Aerodynamic model ...
Numerical modelling of spatio-temporal patterns in a DC-driven gas discharge-semiconductor system
Özden, Gözde; Rafatov, İsmail; Karasözen, Bülent; Department of Scientific Computing (2015)
In this thesis, numerical modelling of temporal and spatial pattern formation in the planar layered system, consisted of a DC driven planar gas discharge layer, coupled to high ohmic semiconductor layer, is carried out in 1D and 2D Cartesian geometry. Numerical model includes continuity equations for ions and electrons, the Poisson equation for the electric field, the energy balance equation for the background gas. The conditions correspond to a transition from the Townsend regime to the glow discharge. Cal...
