Invited by the Noise and Vibration Laboratory of Institute of Acoustics, Prof. Igor Chunchuzov from Obukhov Institute of Atmospheric Physics in Russian Academy of Sciences is carrying out researches at IACAS as foreign researcher of Chinese Academy of Sciences during Arp. 6 to Jun. 1, 2012.

On Apr.26, Prof. Igor Chunchuzov gave an academic lecture titled “Modeling of the effect of a fine layered structure of the atmosphere on infrasound from pulsed sources”.

In the lecture, Igor presented his research findings during his studies at the University of Mississippi in the USA about propagation model in the fine layered structure of the atmosphere on infrasound. Igor creatively built modeling of fine layered structure of the atmosphere from the respective of infrasonic nonlinear mechanism. He explained the scientific singular phenomenon rationally: the acoustic shadow zone probed the infrasonic signal and proved the rationality of this model through the infrasonic signal data produced by Ecuador Tungurahua volcanic eruption on Jul.15 in 2006. The modeling of fine layered structure of the atmosphere has become important in the long-range infrasonic propagation theory field. In the following days, Igor will complete Chinese first infrasonic monitoring network, create earthquake infrasonic propagation model and analyze infrasonic signal with researchers from the Noise and Vibration Laboratory.

Resume:

Igor Chunchuzov graduated from Lomonosov Moscow State University and got his doctor degree of Physical and Mathematical Sciences in the year of 1992. He has been engaged in scientific research on infrasonic propagation theory in Obukhov Institute of Atmospheric Physics in Russian Academy of Sciences from 1982. Igor is active in international programs and has been to the University of Mississippi, the Canadian Remote Sensing Center, the University of York and the University of Bergen for research purpose. He has published more than one hundred papers, of which 40 are SCI articles. Yang Xunren of IACAS had also cited Igor’s early research results in his monograph of Atmospheric Acoustics.
