The American Water Resources Association (AWRA) 2025 Spring Conference: Development Risks & Challenges in Changing Climate Conditions is co-hosted with the AWRA Alaska State Section. The main object of the conference is for participants to connect and contribute to important conversations about impacts to the cultural and socioeconomic health of the planet and all life as we know it related to water and changing climate conditions. Climate change is increasingly causing severe weather events, changes in weather patterns and altering hydrologic cycles. These increasing uncertainties are posing significant risks to current and future development.
GEWEX Session
Topical Session C – A Broad-Based Community Approach to Modeling, Observations, and Prediction of Water Resources Across Climate Timescales over the continental United States
Session Description:
The Global Energy and Water Exchanges (GEWEX) core project of the World Climate Research Programme (WCRP) is developing a so-called Regional Hydroclimate Project (H2US) over the continental US to bring the observational, modeling, and social science communities together to advance the state of the science and our predictive capabilities to better characterize the water, energy, and carbon cycles. Submissions are invited that explore co-design, inter- and transdisciplinary approaches to water cycle science for a better understanding and quantification of water resources now and in the future. Especially relevant are papers that explore ways to evaluate, improve and integrate existing surface observational networks across regional to continental scales, in the context of terrestrial-based and spaceborne remote sensing, to support of Earth system modeling of the water-cycle, and regional, national and global operational weather and hydroclimate monitoring and modelling efforts. An outcome of this work is envisioned as a ‘Digital Earth’ representation of the water cycle over the US to better support the water resources community.

The 2025 CFMIP-CloudSense Meeting on Circulation, Clouds, and Climate will be held July 7-10 at the University of Exeter, Exeter, UK.
This 4-day conference will focus on the following topics, considering models, observations, and laboratory experiments on a wide range of scales:
- Cloud processes: What processes control cloud phase, cloud radiative effects, and precipitation?
- Cloud microphysics: What processes control cloud microphysics, including cloud-aerosol interactions and their impact on climate?
- Circulation and climate dynamics: How do clouds couple to circulations and what role does this coupling play in weather and climate?
- Climate feedbacks and sensitivity: How do clouds respond to external perturbations? How do clouds influence climate sensitivity and patterns of change?
- Energy Imbalance: How do we measure, model, and understand the factors controlling Earth’s energy imbalance?
- Convection: What processes control shallow and deep convection including organization, and how do these interactions affect climate and weather?
The conference will consist of oral presentations, poster sessions, and social/networking events. The conference will be held in-person only.
Please use this google form to submit your abstract for the meeting (DEADLINE extended to Friday April 11, 2025 @23:59 EST).

International Mountain Conference
Dates: 14–18 September 2025
Location: Innsbruck, Austria
The International Mountain Conference (#IMC) builds upon the previous mountain conferences and aims to continue this scientific conference series exclusively targeted towards mountain research. The key goals of the conference are to synthesize and enhance our understanding of mountain systems, in particular their response and resilience to global change. Two GEWEX-related sessions are listed below.
FS 3.316: Precipitation Changes in Mountainous Hydroclimates
Conveners: Michael Brody, Lucia Scaff, Paolo Arias, John Pomeroy, Ali Behrangi
In this session, the conveners plan to explore the research on mountain precipitation, how it changes in a changing climate, and how to tackle the observation-modeling mismatch. Papers are invited that discuss the various observation strategies of precipitation in mountainous regions, novel methods of observation including those that use AI/ML, Earth observation/remote sensing and/or citizen science. Papers are also invited that discuss model advances and evaluate modeling and reanalysis products against in-situ and remote sensing observations in mountainous regions to address the lack of observations.
FS 3.116: High mountain hydrology and cryosphere under global change: observations, modelling, prospects
Conveners: Chris DeBeer, John Pomeroy, Ignacio López Moreno, James McPhee
There is a global need to better understand high mountain atmospheric, hydrological and cryospheric processes, improve their prediction as coupled systems, and diagnose their sensitivities to global change to promote water sustainability. This session welcomes contributions addressing any of the critical research questions, and particularly welcomes contributions on observations from instrumented mountain catchments, theoretical advances and on evaluation of hydrological and atmospheric models using observations to better understand model performance and to see if models reproduce known aspects and regimes of the coupled atmospheric-cryospheric-hydrological system.
AOGS2025
Dates: 27 July–1 August 2025
Location: Singapore
The next Asia Oceania Geosciences Society 2025 (AOGS2025) is set to take place in Singapore from 27 July to 1 August 2025. The eight geoscience disciplines of the society—Atmospheric (AS), Biogeoscience (BG), Hydrological (HS) Interdisciplinary (IG), Ocean (OS), Planetary (PS), Solar & Terrestrial (ST), and Solid Earth (SE)—are the focus of the annual meeting, which is open to scientists, researchers, and practitioners in these fields. GEWEX is helping to convene the following session:
Session Title: The Third Pole Environment and High Mountains of Central Asia – Hydrometeorological Processes and Human Dimension
AS – Atmospheric Sciences
Conveners: Dr. Petrus (Peter) van Oevelen (George Mason University), Prof. Li Jia (Chinese Academy of Sciences), Dr. Xin Li (Chinese Academy of Sciences), Prof. Yaoming Ma (Chinese Academy of Sciences), Dr. Toru Terao (Kagawa University)
Busan IAMAS-IACS-IAPSO Joint Assembly 2025 (BACO-25)
Dates: 20–25 July 2025
Location: Busan, Republic of Korea
BACO-25 will take place over six days in July, when colleagues from academia, government, and industry worldwide will engage in scientific presentations, discussions, information exchanges, and international cooperation in the Earth sciences. A session of interest to the GEWEX community is listed below.
Session title: JCM02 Cryosphere changes and potential drivers in High Mountain Asia
Conveners: Mohd. Farooq Azam, Lijuan Ma, Raaj Ramsankaran, and Peter J. van Oevelen
Description: Understanding the response of the High Mountain Asia (HMA) cryosphere to climate change is crucial for millions of people living downstream who partly depend on meltwater. Changes in snow cover and permafrost still need to be better understood. Contributions based on remote sensing, in-situ observations, or numerical modeling of cryosphere changes in the HMA are invited. The conveners especially encourage studies integrating atmospheric and cryospheric interactions with remote sensing data and exploring the potential drivers behind observed changes.
The Land surface Interactions with the Atmosphere over the Iberian Semi-arid Environment (LIAISE) project, part of the international HyMeX initiative, focuses on enhancing our understanding of land-atmosphere-hydrology interactions in Spain’s semi-arid Ebro basin, a region characterized by its significant agricultural activities and contrasting natural dry zones.
This conference aims to unite researchers specializing in estimating the various components of the surface water and energy cycles experimentally using in-situ observations, via remote sensing data and/or models, from the leaf to the regional scale. The emphasis will be on semi-arid bread-basket regions.

The 2025 Gordon Research Conference (GRC) on Radiation and Climate will focus on key uncertainties in radiation and climate science with particular emphasis on novel approaches to bridge observations and modelling across scales to advance our physical understanding and predictive capabilities. This is timely, with global Earth observations and high-resolution models approaching process scales. The program will capitalize on novel Earth observations as well as the transformation of global climate modelling through computational advances and AI.
This GRC will be held in conjunction with the “Radiation and Climate” Gordon Research Seminar (GRS).
