Very Large-Eddy Simulation (VLES)

Very Large-Eddy Simulation (VLES)

VLES-scale NWP at DX ~100 – 300m grids

  • New advances in computing allow regional NWP down to VLES and LES scales.
  • NCAR has launched real-time WRF-RTFDDAVLES system for US Army DPG, Utah.
  • VLES is proven valuable using LES simulation and verification through case study.
  • Many research works need to be done:
    • How to verify
    • How to use
    • How to improve
    • DA on VLES grids
