AOGS 17th Annual Meeting

Submission Deadline: 21 January 2020

Dates: 28 June - 4 July 2020

Location: Hongcheon, South Korea

Asia Oceania Geosciences Society (AOGS) was established in 2003 to promote geosciences and its application for the benefit of humanity, specifically in Asia and Oceania and with an overarching approach to global issues. Asia Oceania region is particularly vulnerable to natural hazards, accounting for almost 80% human lives lost globally. AOGS is deeply involved in addressing hazard related issues through improving our understanding of the genesis of hazards through scientific, social and technical approaches.

Science Session

As the largest gathering of Earth and space scientists in the Asia and Oceania region, there are many sessions relevant to GEWEX science. Some of them are listed and highlighted below. For a complete overview click here.

Hydrological Sciences

The Third Pole Environment – Hydrometeorological Processes and Human Dimension (HS11)

Conveners: Dr. Peter van Oevelen, Prof. Li Jia, Dr. Xin Li, Prof. Yaoming Ma, Dr. Toru Terao

This session invites contributions dealing with advances in issues to improve the understanding of the interactions of the Asian monsoon, glaciers and the Tibetan plateau in terms of water and energy exchanges in order to assess and understand the causes of changes in cryosphere and hydrosphere in relation to changes of plateau atmosphere in the Asian monsoon system, to predict possible changes in water resources, and to explore the pattern and mechanisms of environment change on Tibetan Plateau and surroundings. A special emphasis is on new projects in the region addressing precipitation in a changing climate as well as those activities that address the human influence on the water cycle.

Natural- and Human-induced Changes in Terrestrial Water Cycle (HS38)

Conveners: Prof Min-Hui Lo, Dr Hrishi Chandanpurkar, Dr Xiaogang He,
Prof Hyungjun Kim, Dr John Reager

This session solicits papers focusing on exploring impacts of natural- and human-induced changes in the spatiotemporal variability of the global water cycle, as well as the relevant mechanisms controlling the natural and anthropogenic-related water fluxes in climate processes from analyses of observations (satellite and in-situ) and model simulations.

Quantifying the Uncertainty of Geographical Dynamic Models in the Era of Deep Learning and Big Data (HS45 )

Conveners: Dr Wei Gong, Dr Zhenhua Di, Prof Qingyun Duan, Dr Chiyuan Miao, Dr Aizhong Ye

The goal of this session is to build a bridge between the community of deep learning/big data and hydrological modeling, bring the pioneering works together and find some ways to integrate hydrological models (as well as other geophysical dynamic models) with deep learning, and improve both the model performance and our understanding about the physical processes.

Atmospheric Sciences

Asian Precipitation Experiment (AsiaPEX): Process and Predictability of Asian Hydroclimate System (AS63)

Conveners: Dr. Toru Terao, Dr. S. Das, Prof. Kyung-Ja Ha, Prof. Li Jia, Prof. Shinjiro Kanae

AsiaPEX aims to understand the Asian land precipitation over diverse hydroclimatological conditions for better prediction, disaster reduction and sustainable development. AsiaPEX has six scientific approaches:

observation and estimation of variation and extremes in Asian land precipitation and important variables;
process studies of Asian land precipitation focusing on diverse land-atmosphere coupling;
understanding and prediction of variability of Asian hydroclimatological system from subseasonal to decadal time scales;
high resolution land surface hydrological modeling and monitoring incorporating impacts of human water withdrawal, agriculture, vegetation and cryosphere;
coordinated observation and modeling initiatives, and
detection and projection of the climate change impact on regional precipitation in Asia.

Research plans, new sub-projects, recent scientific results and outcome from these approaches will be exchanged.

Diurnal Cycle of Precipitation in Observations and Weather and Climate Models (AS32)

Conveners: Dr. Shaocheng Xie, Dr. In-Jin Choi, Prof. Hiroshi Takahashi, Dr. Kuan-Man Xu

This session invites presentations in the following areas:

Observational studies that have a direct bearing on understanding and improving model representations of diurnal cycle of precipitation;
Process studies that utilize single-column models, cloud-resolving models, large-eddy simulations, as well as NWP techniques in climate models;
Global and regional diagnostics of diurnal cycle of precipitation simulated in weather and climate models such as those used in numerical weather prediction (NWP) and climate modeling centers and from major model intercomparison projects (e.g., CMIP5/CMIP6, GASS diurnal cycle of precipitation project);
Parameterization improvement that leads to improved simulation of the diurnal cycle of precipitation.

Regional Climate Downscaling and Cordex: Challenges and Prospects (AS41)

Conveners: Prof Dong-Hyun Cha, Dr Koji Dairaku, Prof Jason Evans, Prof Fredolin Tangang, Prof Shuyu Wang

This session invites scientists within and outside the CORDEX initiatives to share their scientific findings on various issues related to dynamical and statistical/empirical regional climate downscaling methods.
This session covers the following themes:

Evaluation of regional downscaling techniques (dynamical and statistical methods)
Regional climate projection and understanding of climate sensitivity
Comparison between CORDEX phase 1 and 2
Added-values in regional climate downscaling by comparison with high-quality observation datasets
Development of regional earth system model
Process-based studies on sensitivity to the large-scale forcing, regional forcing, domain size, resolution, physics, etc.
Impact studies of regional anthropogenic forcings such as land-use change, aerosol, and urbanization.
Other issues relevant to regional climate downscaling including application to application sectors.

Environmental Changes in the Mountains of Northern Eurasia (AS67)

Conveners: Prof Akiyo Yatagai, Dr Pavel Groisman, Dr Sunil Khadgarai

Session foci are on the changing distribution of precipitation intensity and frequency in the cold season transition periods when surface air temperature is close to 0 deg.C.
Discussion topics are i) The impact of global warming on the snow/ice distribution and their consequent impacts on the soil moisture and runoff. ii) Interdisciplinary topics on the disasters such as floods, landslides and droughts (including shrinking water bodies) which are caused by the extreme meteorological and/or climatological conditions.
