Special courses of Magister education program

Optics of Fractals

Lecturer: Dr. S.D. Andreev (68 hours)

The basic task of this course is acquaintance of students, specialising in the field of physics of aerosols, theory of energy transfer, with bases of the theory of dispersion of electromagnetic radiation, methods and particular results of experimental researches of optical properties of atmospheric aerosols, with basic physical and technical problems resulting in rather rigid restrictions of existing nowadays opportunities of researches and modern knowledge  about perspectives of development of this part of atmospheric physics.
As basis for the present course have served the own works of the author (experimental researches of aerosol  attenuation and its constituents in nature conditions, researches of spectral absorption of  aerosols, modelling of the optical characteristics of aerosols, researches of temporary and spatial variations of the optical characteristics of the atmosphere), carried out largely together with L.S. Ivlev.

Optics of fractal clasters

Lecturer: Dr. S.D. Andreev (32 hours)

The theory of fractal systems, nowadays one of most active  developing  direction of researches in the field of natural sciences finds the widest application in physics, allowing at a new level to describe many well investigated processes and phenomena, and in many cases to explain some effects, earlier, within the framework of traditional knowledge remaining not clear. One of the most perspective areas of application of the theory, physics of small particles agglomerates, in particular their optical properties, that represents doubtless interest for researches of optical properties of aerosols in connection with a wide distribution of similar formations in atmospheric conditions.
The basic task of an offered course is acquaintance of the post-graduate students specialising in the field of physics of aerosols and the theories of energy transfer with real properties of small particles agglomerates, caused by the features of their structure, and modern methods of their study and description. A basis for an offered course are the literature data and results of own researches of the author. In connection with novelty of a considered material (for the first time given subjects have begun to be studied about 10 years ago), the accessible literature practically is absent (in Russian about ten articles, a little  more in English).

The basics of modern methods of observations of variations of atmospheric parameters by means of rockets, radars, lidars and satellite are considered. The basics of indicated modern methods of research of atmospheric dynamics are considered from uniform positions. Comparing to many similar courses the large attention is given to the analysis of accuracy and opportunities of various methods, connected with their space and temporary resolution. Accuracy and opportunities of various methods, as well as main results of measurements are analized. The lectures are recommended to students, specializing in the physics of atmosphere, ecology, geophysics, physics of ionosphere and radiophysics.

Introduction into chaotic atmospheric dynamics

Lecturer: P.I. Domnin (32 hours)

   The main goal of this course is to apply the concepts and methods of the dynamical system  theory  (DST) or deterministic chaos theory (DCT) to the atmospheric physics problems. The TDS basic notions ( as phase space, phase trajectory, regular and strange attractors, Lyapunov exponents etc.) are introduced and further used  analyzing the dynamics of simple low-dimensional systems (as Van der Paul or Duffing oscillators, the Rayleigh-Benard convection and others). The DST and DCT open the new perspectives for understanding nonlinear atmospheric dynamics.  This is illustrated by detailed analysis of Lorenz s three-dimensional atmospheric model. The important part of the course is devoted to the predictability problems of  nonlinear system dynamical evolution  generally and  atmospheric one in particular. Dynamics of error growth and role of scales on predictability and the necessity of a statistical approach to the forecasting of atmosphere dynamic evolution is explored. The passage from short-scale atmospheric dynamics to global climate dynamics is also outlined. Some ideas aiming to connect these two scales of atmospheric variability are  discussed.
