International Workshop on Climate Downscaling Studies
Date: 2 - 4 October 2017
Place: Room 406, International Congress Center EPOCHAL Tsukuba
Prospectus:
Sustainable Development Goals (SDGs) are common goals for the global community to achieve. Seventeen SDGs havebeen determined in General Assembly of the United Nations in 2015. These goals are composed of three main topics: social
issues, economic issues, and environmental issues. Climate is one of the most important factors that affect many issues
across the main topics of the SDGs.
As local climate information are indispensable for the assessment of local climate or environment, downscaling has been, formore than 25 years, believed to be a good technique to produce such local climate data. On the other hand, someresearchers still suggest that downscaling is only a transient research field, which would disappear if the resolution of global
models (GCM) becomes high enough. There are also more optimistic suggestions that downscaling research field continues
as it responds to the diverse and specific demands of impact study researchers and end-users.
In this workshop, we would like to discuss two main issues.
To guarantee the robustness of the results of downscaling, it is very important to explain the climatological andmeteorological mechanism of local climate change. By using downscaling results, we have two kinds of advantages
compared to AO-GCMs results.
(1) High resolution response to orography, land-use or SST.
(2) The effects of synoptic- to meso-scale phenomena.
Here, we hope to discuss on the mechanisms of local climate change, by using downscaling methods.
We will also discuss how “improved coordination between the climate study researchers and impact study researchers orend-users” can be facilitated. For this purpose, the following three topics are handled, with regard to both dynamicaldownscaling (DDS) and empirical statistical downscaling (ESD):(1) Expanding the scope of application of dynamical and statistical downscaling to other sectors and research fields.
(2) Progress of interdisciplinary research using downscaling.
(3) Applications of dynamical and statistical downscaling in Asian countries.
In the workshop, we expect to have a free discussion on the potential of downscaling research.
