| Summary: | (POD) of 100%. One summer equation had a CSI of 55% 139xl85 kilometer area centered at Whiteman Air Force Base. 1500 CST) was detected. Last flash times tended to be A cloud-to-ground lightning summary was developed for a A preferred track for springtime thunderstorms was Although diurnal distributions of lightning flashes and early morning. The percentage of positive flashes and POD of 85%. Two thunderstorm decision models were combined responses from the equations with other constructed using the seasonal regression equations and could not be disregarded. The four spring and fall disappeared during the fall. First flash times for examined for thunderstorm and non-thunderstorm periods on a fall. A summertime peak between 1800-2100 UTC (1200- increase of negative flashes with peak currents below 20 kA was seen, but contamination by intracloud flashes late afternoon and nocturnal maxima were observed during located between the base and the Ozark Mountains. No location. Skill scores for these models were higher meteorological considerations. model performed best with a CSI of 79% and POD of 100%. nearly doubled in 1994 and 1995 compared to previous on independent data, one spring equation had a critical performed better than the two for summer. When tested positive flashes with peak currents below 60 kA. An preferred track was found during the other seasons. random, but preferences were observed for early evening regression equations for thunderstorm prediction seasonal basis. Regression equations developed using these several meteorological conditions such as frontal system showed that thunderstorms were possible at any time, Spatial and temporal patterns, and first stroke peak currents success index (CSI) of 59% and probability of detection than those for any individual equation. The spring the spring and summer. The nocturnal maximum thunderstorm events were spread out for the spring and thunderstorm periods. Decision models were presented that variables distinguished thunderstorm periods from non were analyzed from 1989-1995. Stability indices were years. An increase was observed in the number of |
