Northern Eurasia Earth Science Partnership Initiative

NATO "Science for Peace" Program and NEESPI Joint Workshop

Extreme precipitation events: their origins, predictability and societal impacts: Statistics in observations and modeling, Odessa State Environmental University , Odessa, Ukraine, May 11 - May 16, 2006

NATO "Science for Peace" Project 981044 has been awarded to the international team of researchers from four countries in early 2005. Scientists from Meteorological Institute at the University of Bonn (MIUB), Bonn, Germany; P. P. Shirshov Institute of Oceanology of the Russian Academy of Sciences (IORAS), Moscow, Russia; Scripps Institution for Oceanography (SIO), La Jolla, California, USA; and Odessa State Environmental University (OSEU), Odessa, Ukraine came together to address one of the critical issues of contemporary climatic change: extreme precipitation events, their origins, predictability, and societal impacts in the Northern Extratropics. Research objectives and a significant fraction of the study area of the Project belong to the NEESPI domain. Therefore, cooperation and data and ideas exchange with the NEESPI scientists involved in similar research have been established and formalized by joining the Project team to the NEESPI family of researchers in autumn 2005. The present workshop is the third one for the Project Team and the first workshop where the scientists from other NEESPI projects and the NEESPI Project Scientist attended and participated in the Project activities. Achievement reports of the research groups in four countries, sharing results from current accomplishments and planning of future collaboration within the Project and with other NEESPI projects, the data availability and exchange, and precipitation modeling were the major topics discussed at the meeting in the ambient atmosphere of the Oceanography Observations Laboratory of the Odessa State Environmental University just a few steps away from the Black Sea shore.
