AGU Fall Meeting
2018
Dates: 10-14 December 2018
Location: Washington, DC, USA
Submission Deadline: 1 August 2018
This year’s fall meeting of the American Geophysical Union marks the organization’s 100th year. As the largest gathering of Earth and space
scientists in the world, there are many sessions relevant to GEWEX science. Some of them are listed and highlighted below.
Section: Global Environmental Change GC086: The Global Water Cycle: linkages of ocean salinity with the atmosphere and terrestrial hydrology Session ID: 53319
This session highlights water cycle research that describes linkages between the ocean, atmosphere, and land hydrology. Contributions are invited on all aspects of water cycle research including analyses undertaken using
in situ and remote observations from current (e.g., SMAP, SMOS, GRACE, GPM, GCOM-W, CMORPH-series), past (e.g., Aquarius, TRMM), and future (e.g., SWOT, GRACE-FO) satellite missions, estimates based on numerical models, data assimilation systems, and climate model projections. We particularly welcome contributions that consider multiple realms (the ocean,
atmosphere, land surface and subsurface), and provide compelling evidence for linkages between these, describing coherent water cycle variability and change. We welcome global and regional assessments, and contributions that underscore the imperative to augment and maintain the existing water cycle observing system to ensure that ongoing long-term changes are accurately measured and quantified.
GC090: The Third Pole Environment (TPE) under Global Changes
The Tibetan Plateau and surrounding mountain regions, known as the Third Pole, cover an area of > 5 million km2 and are considered to be the water tower of Asia. The Pan Third Pole expands on
both the north-south and the east-west directions, going across the Tibetan Plateau, Pamir, Hindu Kush, Iran Plateau, Caucasian and Carpathian, and covering an area of about 20 million km2. Like the Arctic and Antarctica, the Pan Third Pole’s environment is extremely sensitive to global climate change. In recent years, scientists from around the globe have increased observational, remote sensing and numerical modeling research related to the Pan Third Pole in an effort to quantify and
predict past, current and future scenarios. Co-sponsored by TPE (www.tpe.ac.cn), this session is dedicated to studies of Pan Third Pole atmosphere, cryosphere, hydrosphere, and biosphere and their interactions with global change. Related contributions are welcomed.

Section: Atmospheric Sciences
A015: Arctic Energy Balance and Relevant Atmosphere and Surface Processes: Current Understanding and Challenges
The Arctic is experiencing more rapid changes than anywhere else on Earth with far-reaching socioeconomic implications. Arctic climate variations in the last decade are strong indicators of the important yet delicate coupling between atmospheric and surface processes in the region.
Projected Arctic responses to rising CO2 by state-of-the-art earth system models still exhibit large spreads in key parameters like temperature, sea ice loss, and ice sheet melt. This spread partly stems from an incomplete understanding of the processes that affect energy flows in the Arctic, especially those linking the atmosphere and cryosphere. We invite observational, modeling, and theoretical studies of the Arctic energy cycle, heat transport by atmospheric and oceanic
circulations, and their relation to clouds, water vapor, cryosphere processes. This session is intended to provide a forum for reviewing our current understanding of Arctic energy balance and outline the challenges that lie ahead for advancing Arctic climate change prediction.
A070: Mesoscale and severe convective storms: understanding, and model development and
evaluation Session ID: 46885
Mesoscale convective systems (MCSs) are significant rain-producing weather systems over the globe. Severe convective storms (SCSs) produce large hail, damaging winds and/or tornadoes, and torrential rainfall, causing substantial damages. Quite often, SCSs are associated with MCSs particularly at
the mid-latitudes. The physical understanding about factors impacting the initiation, intensity, and evolution for both MCSs and SCSs are still low. Model simulations of them are challenging particularly in global models. This session invites recent studies that use observations and/or model simulations at various scales to improve our understanding and model simulations of MCSs and SCSs. The efforts in parameterization development and model evaluation from cloud-resolving models to global
models with various observational data are particularly encouraged.
Session ID: 45344
The earth system operates across a wide spectrum of scales, ranging from thousands of kilometers to a handful of meters. In recent
years, increasing computer power and convection-permitting models (< 4 km horizontal grid spacing) as well as novel techniques such as variable-resolution and multiscale modeling framework are helping to enable high-resolution simulations over large regional, even global, domains at climate time scales. The ability to model smaller scales appropriately has been shown to improve simulations of convection, severe storms, orographic forcing, and their upscale effects to the large-scale
circulation.

Section: Cryosphere
C027. Observing, Modelling, Diagnosing, and Predicting
Hydrological and Earth System Change in Cold Regions
Session ID: 52183 In recent decades warming trends and other changes in climate have driven major and rapid changes in landscapes, ecology, cryosphere, and hydrology, especially in high latitude and mountainous cold regions. Here, the presence of snow, ice, and frozen soils greatly impacts water cycling and Earth system functioning.
Understanding of process interactions and behaviour from experimental and observational programs, and improved representation of these processes within physics-based models are key towards diagnosing the complexities of past change and better predicting future responses in system functioning over various time scales. This session invites papers that describe field and modelling studies to address process interactions, the changing nature of hydrological, hydrometeorological and Earth systems in
response to climatic drivers, and the diagnosis and prediction of change. Studies dealing with biogeochemistry and the integration of water quality and water quantity monitoring and modelling across cold region landscapes and water bodies are also welcome.
C025: Modeling of the Cryosphere: Seasonal Snow
Section: Hydrology
H007: Advances in Integrated Observations, Modeling and Predictions for Weather,
Climate, and Impact Assessments Session ID: 50552 SWIRL Theme: Extreme Events & Hazards
Improved observational, modeling, and prediction systems are essential for assessing resilience and vulnerability
characteristics of hydrometeorological events, and they also contribute to resolution of water security issues. The development of new technologies and strategies to improve the collection and distribution of observations is therefore central for adaptation and mitigation of the impacts from severe weather events and climate extremes, as well as for better support of water management policies. Contributions
that demonstrate the use of observations and models in addressing extreme hydrometeorological events are invited. Developments of observational and information systems that discuss ways to increase their effectiveness are also solicited. Presentations on advances in integration of observations from various sources are of high interest. Educators and students involved in programs on Earth observing systems for weather, climate, and hydrological studies are also invited to contribute to this
session.
H014: Advances in Understanding Land-Atmosphere Interactions in a Changing Environment Session ID: 46923
Land-atmosphere interactions are a key component of the Earth System. Spatial and temporal
variations in surface characteristics (e.g., soil moisture, vegetation) and attendant land-atmosphere fluxes (e.g., evapotranspiration) can feed back on local climate, including hydrometeorological extremes such as heatwaves and drought. Observing, and hence, modeling of coupled land-atmospheric processes is a major challenge due to the complexity of the processes involved and scale heterogeneity of the land surface. This session invites studies employing novel observational or modeling
frameworks to elucidate time and space variations in the strength of coupled land-atmosphere processes and feedbacks (from bedrock to boundary layer). Studies integrating meso-scale networks (e.g., OKMESONET, ARM-SGP, and AmeriFlux), field campaign data (e.g., PECAN, LAFE, HI-SCALE), or satellite data are of particular interest. Also, studies addressing the quantifiable role of land-atmosphere processes in weather predictability and climate variability and change, for example in the context of
the CMIP6 participating models, are welcomed.
