Session Summary

This session presents the latest progress of Monsoon East Asia climatic responses to different levels of warming. It’s designed to: 1) identify the responsive hotspots to an extra 0.5°C warming, and provide reliable fine-resolution climate and extreme projection under 1.5°C warming in East Asia using downscaling methods; 2) investigate the inter-decadal variations of the atmosphere-ocean interaction, and the feedback mechanism of East Asia Monsoon to 1.5/2°C warmings; and 3) provide information on the optimized path of China's future carbon emission and management to achieve 1.5C warming limit. Participants are invited to submit abstracts to this session.

Session description

To maintain the future sustainable development over Asia at local to regional scales, and to regulate future carbon management, it is of great importance to provide scientific knowledge of fine resolution tempo-spatial responses of East Asia monsoon climate to various levels of warming. This session presents the latest efforts of Monsson East Asia climatic responses to different levels of warming. It is dedicated to identify the responsive hotspots to an extra 0.5C warming and the controlling process in the regional earth system, and investigate the characteristics of the inter-decadal variation of the atmosphere-ocean interaction under different levels of warmings. Providing reliable fine-resolution climate and extreme projection under 2 and 1.5°C warmings is extremely important to regional end-users ranging from general public to policy makers. Under the common framework of CORDEX, the added values of high-resolution dynamical and statistical downscalings are systematically evaluated. The fine tempo-spatial structure and response intensity of the East Asian Monsoon System and extremes to various levels of warming will be simulated. The regional responsive hotspots can be identified, and the impact of different warmings on the regional energy budgets, water resources and ecosystem will be discussed. The session also includes the topics on the connection between carbon emission and changes in East Asia climate extremes, and the optimized path of China's future carbon emission and management to achieve 1.5C warming limit.

The session is open to all ICRC-CORDEX 2019 attendees although the number of participants is limited to 55.
