| Summary: | 1986 to 1993. Active and inactive lightning days were A lightning climatology within 50 km of nine outdoor venue A linear regression routine was developed to predict the active days than on inactive days. At the 850 hPa level the and eight selected inactive days. At the 500 hPa level the and temporal patterns were analyzed for July and August from anticyclone centered in northern Georgia. Strong correlation anticyclonic southwesterly flow throughout Georgia. On based on the thermodynamic variables. At the inland called CAPE 2000 with a correlation coefficient of .70. coefficients of .60 and .56, respectively. Logistic composited dewpoint depression was approximately 8 C less on CSI of 50.3%, but a false alarm rate of 46.6%. The linear density exhibited large year to year variability. Although flash density was observed. The patterns of ground flash inactive days the vector averaged winds exhibited a large independent data-- inactive days versus all other days--had a isolated and thermodynamic parameters examined. Logistic lighting days. The critical success index is nearly 80% and lightning flash category within 50 km of Athens, Georgia locations for the 1996 Summer Olympics is produced. Spatial locations, no pattern was found in the spatial distribution of cloud-to-ground lightning: the strike locations were parameters to differentiate active days from inactive days. progression of lightning with a broad minimum from 0600 UTC random. At the coastal location, an inland maximum in ground regression model was not an exceedingly strong predictor. regression routines were developed using the aforementioned regression was used to predict active days versus inactive Showalter stability index and K index had correlation synoptic charts were produced for eight selected active days The coefficient of determination for the model was .3243. the probability of detection is over 93%. A model for there was great day to day variability, there was a diurnal thermodynamic variables. The most highly correlated was a to 1400 UTC and a sharp maximum near 2200 UTC. Composite variation of convective available potential energy (CAPE) vector averaged windfields on active days revealed weakly was found between lightning activity and several of the |
