Global climate change possibly increases weather disasters such as heat wave, gale, torrential rain, and heavy snowfall. Abnormal global-to-synoptic scale phenomena at least lay behind frequent occurrence of local-scale extremes. The relation between large-scale pattern and local-scale abnormal weathers has recently been scrutinized by statistical analysis of high-resolution data derived from artificial-satellite observation and numerical simulations. Moreover, impact assessment of climate change to various sectors like water resource management, agriculture, energy control should be reduced to adaptation policies for industries and local governments including urban areas. This reduction generally requires a close communication between scientists and stakeholders, with an aid of storyline approach to represent uncertain information on climate change. Therefore, studies on climate change, if limited to East Asia, range from global to urban scales and are interdisciplinary from fundamental to applications. This session calls for research topics in various related field, and the participants can share possible future extensions of climate change studies.
