On May 20th 2016, Professor Byung-Ju Sohn, the Dean of School of Earth and Environmental Sciences, Seoul National University, brought an wonderful lecture named "Use of long-term satellite data examining strengthened Walker circulation over last three decades" for students in School of Earth Sciences, Zhejiang University.

Professor Byung-Ju Sohn is also the chairman of International Radiation Commission (IRC) under International Association Of Meteorology And Atmospheric Sciences (IAMAS), his main research area are: cloud-radiative interaction,satellite meteorology, satellite sensor calibration, sand-dust monitoring and sea ice monitoring etc.

  

Professor Byung-Ju Sohn first introduced the Pacific Walker circulation and its changes in recent years, as well as its enhancement, based on the climate simulating and satellite observations. Then based on the situation and changes of water vapor transportation and precipitation in nearly 30 years, he analyzed the variation tendency of atmospheric stability from the aspects of diabatic heating and adiabatic cooling. The result shows that the tendency under CMIP5 mode is greater than the ERAI and the MSU/AMSU, the - PWCI simulation tendency is greater than + PWCI. Finally, professor Byung-Ju Sohn indicated that improving the convective parameterization schemes is conducive to minish the uncertainty of Walker circulation strength simulation.

The lecture broadened the scientific horizon of our students and was ended in a harmonious academic atmosphere.
