Welcome

We are pleased to announce the 7th International Workshop on Nonhydrostatic Models, to be held on November 17–19, 2025, followed by the DYAMOND meeting on November 20, 2025.

We invite researchers engaged in global storm-resolving models (GSRMs) and related analyses. We particularly welcome participation from those involved in global GSRM intercomparison experiments, such as the Sendai Protocol (Takasuka et al. 2024) and ECOMIP.

Participants in the WCRP Global KM-Scale Hackathon are also warmly encouraged to join these events.

We look forward to seeing you in Morioka!
