Basic scientific directions
 Research of
climatic variability in the ocean- atmosphere system and its
regional manifestations;
Research of the
processes of dynamic and thermal atmosphere - ocean interaction;
Study of turbulent
structure and wave processes in the boundary layers of the
atmosphere and the ocean.
Projects

fluctuations (code "The World ocean and climate of Ukraine").
• "Research of spatial variability of hydrophysical fields and
processes of interaction in the ocean-atmosphere system" (code
"Ocean-atmosphere");
• "Research of climate changes in the ocean-atmosphere-lithosphere
system on global and regional scales" (code "Ocean-climate");
• "Development of the experimental system of control and prognosis
of the wind-wave fields for the regions of oil-gas production in the
north-western part of the Black Sea" (code "Ocean-oil");
• Project of the State Committee on science and technique of Ukraine
"Role of the ocean in the changes of natural environment and
climate";
• Project of Ministry of science and technologies of Ukraine
"Research of the ocean as the energy and dynamic system of the
global level with the purpose of prognosis of changes of weather,
climate, navigation conditions and realization of marine
technologies";
• Project of Ministry of ecology and natural resources within the
framework of the Climatic program of Ukraine "Development of a
numerical model and use of modern methods in research of climate of
Ukraine in connection with variability in the ocean-atmosphere
system";
• NATO project "Climate variability and extremal hydrometeorological
events in the Eastern Europe".
In the 70ies a few modifications of a submerged gradient station (SGS)
was developed in the Department. They were used to investigate
small-scale atmosphere-ocean interaction in the open sea from the
shipboard of a research vessel. Works with SGS were conducted within
the framework of the international project "Sovfrans" ("Cofrans" ) .
A stationary gradient mast was set at a distance of 300 m from the
coast in the Experimental Department of Marine Hydrophysical
Institute (Katsiveli). In the 70- 80ies a large amount of unique researches of small-scale
interaction between the atmosphere and the ocean was performed.
The results of these researches are published in two monographs
and numerous papers. Based on the materials of studies one doctoral
and four candidate theses were defended.
Later and up to now the investigations of small-scale atmosphere
and ocean interaction were continued on the stationary oceanographic
platform (Katsiveli) and on the drilling platform in the Karkinit
bay located at a distance of 70 km off the Tarkhankut cape. These
researches of Air-Sea Interaction Department were accompanied by implementation of
climatic programs. The results of the climatic programs served a
basis for defending two doctoral and two candidate theses.
The results of these researches are used, in particular, to control
and to prognoses wind-wave fields in the region of gas-oil production
and to estimate recreation value of seaside resorts of the
Mediterranean-Black Sea region. more information
Results
- vertical structure of the Reynolds wave tensions in the
near-water atmosphere and the sea upper layer is studied.
Contribution of wave tensions to the compound momentum flux is
estimated;
- it is shown experimentally that the law of spectrum of Phillips
equilibrium interval can be applied only approximately, and
non-linearity of harmonics of the basic mode results in a noticeable
deviation of the dispersion relation from the linear one in the area
of doubled frequency of energy-carrying waves;
- the model of thermohydrodynamic layer of wave mixing is
constructed. Nonlinear motion induced by heat waves is investigated;
- physical regularities of formation of solar and long-wave
radiation on the ice-free surface of the World ocean are studied;
- complex of the automated instruments for satellite communication
channels is developed;
- monitoring of hydrometeorological fields in the opened part of the
Black Sea from the oceanographic platform in Katsiveli and from the
drilling platform on the natural gas field "Golitsino" on the Black
Sea north-western shelf is carried out since 1992;
- numerical model of the wind-wave prognosis for the opened part of
the Black Sea with the lead time 3 days is constructed;
- regional numerical model of the atmospheric circulation adapted
for territory of Ukraine is constructed. Regional numerical
calculations are carried out;
- based on the analysis of variability of multi-year global and
regional data studied are the processes of interaction in the
ocean-atmosphere system (forming the climate in Ukraine) on
seasonal, inter-annual and multi-year scales;
- methods of research and prognosis of climatic variability of
hydrometeorological fields including downscaling and modern
mathematical and statistical methods are developed;
- a base of global and regional hydrometeorological data including
all accessible at present data arrays from the international sources
and the information of routine observations on some meteorological
stations of Ukraine is formed.
