Precipitation drives the atmospheric storage, movement, and quality of water. It is both the primary source of freshwater and a major driver of natural hazards. While a fundamental hydrologic flux, precipitation comprises the most challenging processes to estimate, model, and predict, because of its variability at all scales and its evolving interactions with the water, energy, and carbon cycles under a changing climate. It is therefore a major component of uncertainty in weather predictions and cliamte projections, with significant implications for our ability to quantify water cycle dynamics, inform decision making, and predict hydro-geomorphic hazards in response to extremes. A key to these efforts is model-observations synergy to advance precipitation science by jointly enhancing the accuracy of modeled processes and our insight into observations across space and time scales.

This year’s annual GLASS Panel Meeting (by invitation only), will review progress of the GLASS working groups and projects and hear updates from non-GLASS projects with related research objectives. As one of the four panels of the Global Energy and Water Cycle Exchanges (GEWEX), a core program of the World Climate Research Program (WCRP), the new GEWEX Science Plan and the WCRP Lighthouse activities will be at the heart of these discussions.
Meeting objectives
- Share progress of existing projects;
- Determine if there are weaknesses in the current portfolio of GLASS projects, exposing scientific questions and areas where we should be promoting active coordinated research projects;
- Discuss structural changes at the World Climate Research Program and determine how GLASS can best contribute to the Lighthouse Activities.

This year’s GHP meeting (by invitation only) will be used to review the state of the current ongoing actions (RHPs, CCs, Networks and the links with the Data Centers). GHP members and project leads will evaluate ongoing and planned GHP activities and asses future actions to ensure that the Panel contributes effectively to the leading role that GEWEX plays in the hydrological and climate sciences and related modeling activities. The GEWEX Science Goals and the WCRP Lighthouse Activities will be at the heart of these discussions, which will result in improved interactions between the GEWEX RHPs and strengthen their involvement in the crosscutting projects.

The overarching goal of this workshop is to establish a regional project in Central Asia on hydroclimate, water resources, food security, conservation, and land use, led by regional scientists and stakeholders. An important driver for that ambition is to better observe and predict climate change and its effects and to support adaptation and mitigation measures, to support land use planning and sustainable food supply. A crucial aspect for any successful regional development is the existence of a strong and cohesive scientific and stakeholder network, to establish a community of scientists and stakeholders with relevant key interests.
In 2022 ANDEX became an initiating Regional Hydroclimate Project (RHP) of the GEWEX Hydroclimatology Panel (GHP) with the main goals of (i) establishing a research agenda focused on key hydroclimatic issues of interest to the Andes region; (ii) connecting the scientists working in the Andes with global and regional initiatives, and (iii) creating a scientific framework to contribute with the decision-making process for the sustainable development of the region.
The main objectives of the 2023 ANDEX meeting in Santiago are to:
- meet with the Scientific Committee and the coordinators of the different ANDEX teams to discuss the current state and recent activities of these groups,
- work on the development of the Scientific Plan of the ANDEX program, including its specific objectives, main scientific questions, key research activities, and milestones and deadlines in the short, medium and long terms and,
- present the main goals and regional relevance and potential of the ANDEX program to the attendees of the GEWEX High Level Meeting.

The 35th GEWEX Scientific Steering Group (SSG-35) meeting is a by invitation only and will take place in Santiago, Chile from Monday to Thursday, 1–4 May 2023. Holding the GEWEX SSG in Santiago is a recognition by the international community of the tremendous effort of the Andean research community to coordinate their effort of understanding the water cycle of the this region.
The GEWEX SSG-35 will focus on internal matters: the new GEWEX Science Plan for GEWEX’s Phase IV (2022-2032), how that translates to current and future panel activities and how it aligns and links with WCRP’s science priorities, including the WCRP Lighthouse Activities, and each GEWEX Panel will report on their activities in 2023/2024 and plans.
Furthermore, this meeting will also focus on GEWEX activities in relation to our sponsors and international partners and an important part of this meeting is dedicated to discussing preparations for the GEWEX Open Science Conference in 2024.

The upcoming joint Cloud Feedback Model Intercomparison Project (CFMIP) and Global Atmospheric System Studies (GASS) Meeting will be held on 9–13 July 2023 at Sorbonne University in Paris, France.
This 4-day conference will focus on the following topics, considering process and climate studies, and models and observations across a range of scales:
- Convective organization: What controls the organization of shallow and deep convection, and what role does it play in weather and climate?
- Cloud processes: How do micro- to meso-scale processes control cloud phase, precipitation and cloud-radiative effects?
- Clouds-circulation coupling: 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 and what role does it play in climate change?
The conference will highlight the complementarity, for answering those questions, of the suite of available models (LES, CRMs, GCMs, global CRMs, conceptual models) and observations (field campaigns, observatories, satellites).
The conference will consist in oral presentations, poster sessions and breakout group discussions.
In order to submit an abstract, please fill out the form at the following link:
Abstract Submission Form for the 2023 joint CFMIP-GASS Meeting
The deadline for abstract submission is March 30, 2023 (extended).
A registration fee of about 200€ will be collected in April–May. Details will follow in April.
If you have any further questions, please contact us by email (cfmip2023@lmd.ipsl.fr) or check the conference website.
The aim of this workshop is to discuss scientific applications and opportunities emerging from cloud tracking while at the same time providing an overview of key tools and datasets. Such key tools and datasets are expected to play an important role in the analysis of the observations from upcoming space missions focused on clouds and convection including EarthCare, INCUS and AOS, as well as with the model datasets arising from revolutionary development of k-scale models.

The tropospheric lapse rate is the gradient of temperature though the troposphere. In tropical and subtropical regions, it plays a key role in the climate, through its impact on the large-scale circulation and on convection.
The goal of this workshop is to investigate the questions below, by gathering different communities working on tropospheric lapse rate in tropical and subtropical regions.
- How will lapse rate change with global warming?
- How as it changed in a recent past?
- What mechanisms control the lapse rate and its spatial distribution?
- Can past climate reconstructions of lapse rate better constrain its controlling mechanisms and its future variations?
The idea of this workshop is to bolster interactions between different communities that seldomly interact, but who share the same science objectives:
- convection community working on mechanisms controlling lapse rates, for example using cloud-resolving models or conceptual models;
- present-day observation community, observing lapse rate distribution and evolution through radiosondes, satellites and ground-based along-slope observations in mountains;
- mountain weather and climate community working with observations or models, who can shed light on the relationship between tropospheric and along-slope lapse rates;
- paleo-climate community, reconstructing and modeling past changes of lapse rate in various tropical regions.
