Koshlyakov, Mikhail Nikolaevich

The son of a mathematician N.S. Koshlyakov . In 1953 he graduated with honors from the Faculty of Geography of Leningrad University .

Since 1953 he has been working at the Institute of Oceanology of the Russian Academy of Sciences , where, under the guidance of Professor V. B. Shtokman, he graduated from graduate school and defended his thesis .

From 1989 to 2006, he was the head of the Laboratory of Sea Currents, currently he is the chief researcher at the laboratory.

In the mid-1960s, he developed an accurate hydrodynamic interpretation of the well-known method of boxes (reservoirs) in oceanology.

The main scientific achievements are connected with the study of synoptic eddies of the open ocean - a phenomenon whose discovery at the turn of the 1960s and 1970s was an outstanding event in oceanology. He was a direct participant in all the main domestic experiments on the study of vortices, conducted from the mid-1960s to the beginning of the 1990s.

An analysis of the data of these experiments, performed jointly with his students and employees, led to a number of fundamental results on the structure and dynamics of vortices, including the first vortex maps constructed from the calculation results.

Experimental evidence has been obtained for the generation of vortices due to the baroclinic instability of large-scale currents, the interaction between the vortices has been analyzed, the field of vortices in the subtropical and temperate zones of the ocean has been treated as geostrophic turbulence ( POLIMODE , 1977-1978, Atlantic Ocean and Megapoligon, 1987, Pacific Ocean, 1987 )

A description of vortices of record intensity was compiled: the cyclonic vortex of the Southern Polar Front (South Ocean, 1983), the intratermoclinic lens of Mediterranean water (Mesopolygon, 1985, Atlantic Ocean) and the Gulf Stream cyclonic ring (Atlantex-90).

The discovery of synoptic eddies of the open ocean was recorded in 1980 by L. M. Brekhovskikh, V. G. Kort , M. N. Koshlyakov and L. M. Fomin.

Since the early 1990s His research interests are shifting to exploration of the Southern Ocean. In 1992, as part of the largest international program WOCE (World Ocean Circulation Experiment), he leads a Russian-American expedition to the Pacific Antarctic. An analysis of the data from this and other Antarctic expeditions allowed him and his colleagues to obtain a number of important results on the hydrology, dynamics, and climate of the Southern Ocean, including the discovery and calculation of the Pacific-Antarctic cell of the Global Ocean Conveyor.

The most important result achieved in 2003-2004 is to obtain, by mathematical modeling and analysis of experimental data, evidence of the formation of Antarctic intermediate water due to separation and further attenuation of cyclonic eddies of the Subantarctic front.

He has been teaching at the Department of Thermo-Hydromechanics of the Moscow Institute of Physics and Technology since the foundation of the department in 1966, giving a course of lectures on physical oceanography.

Over the years, he was a member of the Soviet-American Organizing Committee POLIMODE (1975-1981), the WOCE Working Group on the Southern Ocean (1990-1993), the WOCE Scientific Steering Group (1993-1996), and the chairman of the WOCE National Committee of Russia (1993-1997 )

Deputy editor-in-chief of the journal “Oceanology”, member of the editorial board of the journal “Physics of the atmosphere and ocean”.
