This webpage shows post-processed ensemble products, including postage-stamp
and spaghetti plots,
ensemble mean in the form of Probability Matching (PM), ensemble maximum,
and neighborhood probability maps, of selected fields. This webpage is for
demonstration purpose. It doesn't include all available ensemble
products generated from the experiment.
Multi-model ensemble system: 26 ensemble members - 19 WRF-ARW, 5 WRF-NMM, and 2 ARPS
(hybrid: initial perturbation + physics perturbation);
4 km horizontal grid spacing; 51 vertical levels; 30 h
forecast initiated at 0000 UTC
Post-processed ensemble products are based on a 15-member sub-ensemble.
The neighborhood probabilities are calculated using a 40 km Radius of Impact
(ROI) and a 2D Gaussian smoother with a sigma value of 10.
2010: a) Expand domain to cover entire continental United
States (CONUS); b) Upgrade to
Change membership combination for WRF ARW and NMM cores.
The CAPS 2010 Spring Experiment Plan document
details the ensemble system configuration.
