Considerable contrasts are evident in the atmosphere between a day in which fires were suppressed and a day in which a dramatic expansion in the areal extent of fires occurred. The period of suppression was associated with passage of a significant trough and intrusion of subsident air over much of Florida. In comparison, the fire outbreak was characterized by adequate instability and moisture for convection, a light surface flows opposing sea breezes, and light winds aloft. This generated stationary convection and considerable lightning leading to initiation of fires particularly outside rain areas. Lightning-initiated fires accounted for 79% of the acres burnts. This study examines the overall trends in flash density, frequency of fire initiation, low-level moisture, mesoscale circulation patterns. The influence of fuel-type and antecedent precipitation on the lag between flash and full-blown combustion are also considered.
