The article focuses on the value of wind profiler data in U.S. weather forecasting. The CAPE forecast improvement from assimilation of profiler data was largely related to an enhanced southeasterly flow of moisture into the area of convective initiation and a westward shift of dryline position, both changes closer to the observations. The 3-h CAPE forecast error fields for 2100 UTC were similar except that the EXP and CNTL errors were not as large as their 6-h forecast counterparts. The modified 850-hPa flow in the CNTL run with profiler data appeared to cause the extra moisture transport and a westward shift in the dryline position. |
