The Global Flood Crosscutting (CC) Initiative is a global project initiated by GEWEX/WCRP that allows the GEWEX Hydroclimatology Panel (GHP) to propagate flood modeling and research knowledge from one region to the other and
synthesize results globally. The goal of this initiative is to identify opportunities where global collaborations can uniquely advance more approaches to understand flood consequences and identify the data, research infrastructure, and initiatives necessary for impactful partnership on this subject. We invite you to attend our next monthly meeting on Friday 2 May at 9:00 a.m. EDT with a presentation from Prof. Thomas Wahl (University of Central Florida). Time will be
reserved for discussing your ideas and engaging with the community on this important subject. Sign up for the mailing list to get the links to the meetings at https://www.gewex.org/floods-cc/! |

Submission Deadline: 1 October 2025 This special issue of Soil invites papers that study soil dynamics using numerical and statistical models. The focus will be on the development of model-based representations, or digital twins, of soil systems to study soil processes, dynamics, and functions from the pore to the landscape scale
and from diurnal dynamics to millennial evolution. By bringing together modelers and models that work on different spatiotemporal scales, the issue aims at synergies between soil hydrology, soil physics, soil geography, and soil ecology to develop holistic models that consider soils and their functions as dynamic systems. This SI is an initiative of the International Soil Modeling Consortium (ISMC, https://soil-modeling.org/) and the 3-4D Soil models working group (https://dbges.de/en/commissions-and-working-groups/working-groups/wg-3-4d-soil-models), part of the German Soil Science Society. |

Dates: 19–21 May 2025 Location: Paris, France
By Invitation Only The GEWEX Upper Tropospheric Clouds and Convection Process Evaluation Study (UTCC PROES) working group was created in 2015 to ultimately advance our knowledge of the climate feedbacks of Upper Tropospheric (UT) clouds. UT clouds,
formed as outflow of convection, play a vital role in the Earth’s weather and climate system by modulating the Earth’s energy budget and UT heat transport. As large-scale modeling is necessary to identify the most influential feedback mechanisms, it is important that the relevant cloud processes are well represented in climate models. Therefore, UTCC PROES goals are to: - Understand the relation between convection, cirrus anvils and radiative heating, and
- Develop observational
diagnostic methods to probe processes that detrain UT clouds from convection
The Upper-Tropospheric Clouds and Convection (UTCC) Process Evaluation Study (PROES) meeting is planned to take place in conjunction with 2025 GDAP meeting. |

Dates: 22–23 May 2025
Location: Paris, France
By Invitation Only The GEWEX Data and Analysis Panel (GDAP) was organized to bring
together theoretical and experimental insights into the radiative interactions and climate feedbacks associated with cloud processes. The central question that governs the GDAP mission is: “how sensitive is the Earth’s climate to changes in radiative and other forcings?” During this meeting, participants will evaluate the progress of current GDAP assessments and projects. They will also engage in discussions regarding potential collaboration and explore new
project opportunities. As one of the four Panels of GEWEX, a core program of the World Climate Research Program (WCRP), the GEWEX Science Goals and the WCRP Lighthouse activities will be at the heart of these discussions. |

Dates: 22–23 May 2025 Location: Toulouse, France The Land surface Interactions with the Atmosphere over the Iberian Semi-arid Environment (LIAISE) project aims to improve
understanding of land-atmosphere-hydrology interactions in Spain’s semi-arid Ebro basin, which is an important “bread basket” region where intensive irrigation contrasts with natural dry zones. The overall goal of this meeting is to bring together 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, notably those with anthropogenically-enhanced surface heterogeneity due to irrigation, crop variability and other activities. The session themes focus on surface energy budget and hydrological processes, atmospheric boundary layer-surface interactions and their potential impact on mesoscale to regional scale atmospheric circulations, and on the basin-scale hydrological cycle with a focus on anthropogenic impacts and processes. |

Location: Vienna, Austria
Dates: 30 June–4 July 2025
Registration Deadline: 1 May 2025 for scholarship This Summer School is devoted to runoff prediction in ungauged basins (PUB), i.e., predicting water runoff at locations where no runoff data are available. This lack of data presents considerable challenges to catchment managers
who require information on water flows for decision making. This course, based on the book Runoff Prediction in Ungauged Basins: Synthesis across Processes, Places and Scales, will provide hydrologists with the theory and methods to address this critical challenge. Masters and Ph.D. students researching catchment hydrology and practicing hydrologists who are challenged by making predictions in the absence of runoff data are invited to attend. |

Institution: Laboratoire de Météorologie Dynamique (LMD), Paris, France
Deadline: Open until filled The French ANR MOBYDYC project aims to improve our physical understanding of low-cloud feedback by
building observable and energetically-constrained feedback mechanisms based on boundary-layer dynamics processes. To this end, it focuses on the spatial morphology of low clouds simulated by high-resolution models and observed by satellites, with an emphasis on stratocumulus. The post-doc proposal addresses part of the MOBYDYC project, namely the analysis of low-cloud morphological feedback constrained by energy conservation. This task can integrate
different approaches and tools such as global climate models, global cloud-resolving models, large-eddy simulations, and observational data. |
