SEMINAR «FLUID DYNAMICS AND THERMODYNAMICS OF CLIMATE»

Prof. Robert Nigmatulin

December 3, 2015

12.00 – 13.30

TPOC-3

Multifunctional zone, Room 303

SEMINAR ABSTRACT:

The Global climate is characterized by the averaged (along the Earth’s surface) temperature, daily and seasonal oscillations, by the precipitation and kinetic energy of atmospheric flows. Change of the climate impacts the ice surface on the polar zones.

The main factors having an influence on the climate:

1.Albedo of the Earth surface, characterizing a  fraction of reflected of the short wave sun radiation;
2.Moisture content (drops and vapor);
3.Greenhouse gases (H2O, CO2, CH4, etc.) content;
4.Intraphase and interphase heat and mass transfer in three phase  system: atmosphere-land-ocean:
-radiation transfer,
-turbulent transfer of heat, CO2, water vapor and water droplet moisture,
-water evaporation and condensation on the ocean-atmosphere interface, precipitation,
-condensation of water microdroplets and cloud formation, reflecting the radiation waves,
5.Heat transfer by the ocean flows (Gulfstream and so on);
6.Astronomic factors: ellipticity of the Earth orbit around Sun, gravitational perturbation of the Earth orbit by Jupiter, Venus, and Saturn, Sun activity.
Problems of the mathematical modelling. Multiscale and singular zones in the ocean. Averaging.
Global warming. Ecological, economical and energetic problems of the Global warming.
