Preface

Abstract

These Conference Proceedings contain the selected papers of the 9th International Conference on Computational Information Technologies for Environmental Sciences (CITES) held on June 3-6, 2019 in Moscow, Russia. The conference was preceded by Young Scientists School which was held on May 27 - 31, 2019.The main theme of the event was subseasonal to decadal weather and climate predictions, covering aspects from the modeling and data assimilation to forecast information delivery and relevant practical applications. At the school 12 lectures were delivered and 14 hours of practical classes were held by experts in the field of climate variability and forecasting, members of Working Group of the World Climate Research Program on seasonal and multi-year forecasts, members of World Meteorological Organization’s Panel of Experts on Seasonal to Long-Range Forecasts (ET-OPSLS) and WMO CCl / CBS Intergovernmental Panel on Regional Climate Activities.The conference sessions were devoted to different aspects of Earth system modeling, long range forecasts and applications. The sixteenth session of the CIS Climate Forum on Seasonal Forecasts (NEACOF-16) was also held on the first day of the conference in the form of a parallel session.During the conference, 4 lectures and 90 reports were presented and discussed in a series of successive presentations. All materials are presented in the conference proceedings and posted on the conference web-site http://www.scert.ru/en/conferences/cites2019/.All contributions, selected for publication in this volume, have been peer reviewed according to rigorous international standards. We are grateful to the reviewers for maintaining the standards and quality of the manuscripts throughout the reviewing process. However, the authors take full responsibility for the content of their papers.The event was organized by Institute of Monitoring of Climatic and Ecological Systems SB RAS and G.I. Marchuk Institute of Computational Mathematics RAS. It was supported by International Center for Theoretical Physics, the World Climate Research Program, Ministry of Science and Higher Education of Russian Federation and Russian Foundation for Basic Research.
