| Summary: | 2-3 times more positive than observed in airmass storms. 2.91 strokes and median first-return stroke peak current of 32.1 kiloamperes (kA). Six percent of the flashes were 800 000 cloud-to-ground lightning flashes from 119 storm and peak current values. Analysis by storm location showed between positive Flash peak currents and echo heights. data to storm type revealed that frontal storm lightning was geographical location, and maximum echo height. Examination ground flash densities within the study region (26.50-34.5" heights, a positive correlation between negative flash lightning characteristics to maximum echo height found a lower multiplicities and higher peak currents (both lowering negative charge to ground had a mean multiplicity of multiplicities and echo heights, and a negative correlation multiplicities and peak currents than in frontal storms, N, 102'-930 W) were in southeastern Texas. The flashes negative correlation between percent positive rates and echo Negative flash peak currents remained relatively constant Negative lightning in airmass storms had slightly higher mean of 1.43 and a median peak current of 36.6 kA. Relating the of the flashes over the entire period found that the highest polarities) than observed in inland storms. Comparison of positive as those in coastal storms, but coastal storms had positive correlation between flash rates and echo heights, a positive; the positive flashes exhibited a mean multiplicity study attempted to characterize these flashes over the entire systems which affected Texas during April-June 1993. This that inland storm lightning flashes were more than twice as The National Lightning Detection Network detected more than their lightning characteristics, relative to their type, three-month period, then classify the storms according to while frontal storms had higher positive flash multiplicities with increasing echo heights. |
