CAPS 2009 Spring Experiment Ensemble Forecast Product


This demonstration webpage shows hourly ensemble products, including postage-stamp chart, spaghetti plots , ensemble mean (in the form of Probability Matching - PM) and spread , and probability maps, of the forecast composite reflectivity and 1-h accumulated accumulated precipitation fields, along with the available observations (composite reflectivity mosaic and NSSL/NMQ 1-h precipitation) valid at the same times.

Multi-model ensemble system: 20 ensemble members - 10 WRF-ARW, 8 WRF-NMM, and 2 ARPS (hybrid: initial perturbation + physics perturbation)
; 4 km horizontal grid spacing; 51 vertical levels for WRF and 43 for ARPS; 30 h forecast initiated at 0000 UTC
NEW in 2009:
a)
Add 8 members using WRF NMM dynamical core; b) Add 2 members using ARPS modeling system The CAPS 2009 Spring Experiment Plan document details the ensemble system configuration.
