Maximum monthly ground flash density values ranged and interannual variability of several lightning parameters: arrival (TOA) sensors which locate cloud-to-ground (CG) August. Mean monthly percentage positive lightning was characteristics, correlation between monthly lightning and Coastal states, especially in Florida during the summer country. The 1989-1994 mean monthly maximum values were February to 2.78 in June. The mean monthly positive first-stroke peak currents. In addition to these lightning flashes as well as measure their polarity, peak current, and from 0.050 km -2 in December along the southern Mississippi from Minnesota southwestward into Colorado from April through Geographically, the monthly maxima for the negative ground flash density, positive ground flash density, highest in December at 16.0% and lowest in August at 3.0%. in December in eastern Texas to 0.12 km-2 in July in northern Kansas. In the percentage positive lightning field a mixture of magnetic direction finders (DFs) and time-of- monthly positive median first-stroke peak current ranged from months. Unlike the negative flashes, the monthly maxima for multiplicity field were generally found along the Gulf multiplicity ranged from 1.26 in December to 1.35 in July. multiplicity.
