Abstract
  • Current error sampling practices at Meteorological Service of Canada
    • Data Assimilation with Ensemble Kalman Filter (EnKF)
    • Ensemble Prediction based on
      • Multi-parameterization approach
      • Stochastic physical tendency perturbations (PTP)
      • Stochastic kinetic energy backscatter scheme (SKEB)
  • Ongoing work on a stochastic deep convection scheme
    • Modification of the Bechtold scheme (Bechtold et al., 2001) to include stochastic component
    • Approach based on the Plant-Craig scheme (Plant and Craig, 2008)
