ClusterTech presented cutting-edge atmospheric modeling research at the workshop "Navigating the Turbulence Grey Zone in Numerical Weather Prediction" organized by the University of Exeter (Exeter, 23-25 June 2025). Mr. Chris Cheung, Senior Director of Technology, showcased a technical poster titled: "Numerical weather prediction at 200 m local resolution based on the unstructured grid CPAS model" - highlighting unprecedented capabilities of the ClusterTech Platform for Atmospheric Simulation (CPAS).

This poster demonstrated how CPAS's unstructured grid architecture enables 200-meter local resolution, significantly advancing fine-scale weather prediction within the critical grey-zone scale (100m–1km). Key innovations included:

  • Use of scale-aware turbulence parameterization for ultra-high-resolution applications.
  • Computational efficiency through Customized Unstructured Mesh Generation and Hierarchical Time-Stepping for ultra-high-resolution local refinement of global mesh for a city.
  • Enhanced cross-scale physics coupling across synoptic scale to microscale.
  • Investigation of near-surface wakes and recirculation near complex terrain.

This research directly addresses core modeling challenges where traditional approaches either lose predictive accuracy for specific locations due to coarse resolution, or involving prohibitively expensive computational resources for large-domain high-resolution simulations. The presentation attracted strong interest from global NWP experts at the premier forum, validating CPAS's approach to high-fidelity atmospheric simulation.

ClusterTech continues to advance CPAS capabilities for urban meteorology, extreme weather forecasting, and regional climate applications.
