This study is aimed at developing of an operational oceanographic system for the Russian sector in the Gulf of Finland and South-Eastern part of the Baltic Sea for operational forecast of hydrodynamic and ecosystem parameters on the basis of high and ultra-high spatial resolution models. The system is presented as a complex of regional and local models; for which a coupled modeling integration at boundary conditions exchange is fulfilled. The models share common mathematical formulation of general motion equations and a unified realization on the basis of programme code modeling modules designed for the ocean modeling – NEMO. The regional model of the Baltic Sea circulation is complemented by a module for the inert matter transport simulation. The latter is set up on the basis of a matter turbulent diffusion model with the use of two consistent equation systems: deterministic and stochastic. The designed operational system consists of two subsystems: operational oceanographic system of the coastal areas of the Baltic Sea and an expert-analytical system of operational monitoring of the aquatic environment and effective response to accidents at sea.
The paper considers the priorities of the state policy of the Russian Federation in the Arctic, from the point of view of the development of scientific research, identified by the main strategic documents of national policy and security in the Arctic zone of the Russian Federation. Measures for implementation of priorities in the development of scientific research in the Arctic can be divided into three main sections: 1. Scientific projects and expeditions in the Arctic; 2. International activities; 3. Coordination and implementation of integrated research in the Arctic. Note that currently the Ministry of education and science of the Russian Federation develops the Analytical Coordination Program “Comprehensive research of the Arctic and Antarctic”, in cooperation with the federal state bodies and Governance of the Subjects of the Arctic zone of the Russian Federation. The mechanism of the Program will ensure coordination between state bodies for integrated scientific researches in the Arctic in the interests of economic and scientific development of the region, and the creation of the scientific, technical and technological reserve in order to ensure of national security in the Arctic zone of the Russian Federation.
Sea level and wave data at Salalah coast (Oman) were used to simulate nearshore waves and current during the tropical cyclone ARB01 (9 May2002). STWAVE model (Steady State Spectral Wave) was applied for nearshore wave simulation, while M2D model ((Two-Dimensional Depth Averaged circulation model) was used to simulate nearshore current. The results of simulations (taking into account the mutual effects of both current and waves) showed that: The significant wave heights generally decrease from about 6m at the domain boundary to about 1 m close to the coast. The wave heights during the ebb period were higher than that during the flood period by about 1.5m. Along Salalah coast, higher waves were found along the eastern side of the domain. This is because the shielding effect of breakwater, which protect the western part of the coast from high waves. Relatively Strong current with values up to 1.5 ms-1 were found in the nearshore region during both ebb and flood periods. The M2D model results also showed cyclonic circulations during these periods which help in the renewal of harbor waters. Generally, the model results showed good agreements with observations in the investigated area.
