Intense forest fires, such as those seen in the 2019–20 Australian bushfire season, can create their own weather systems that can produce lightning (also called Fire Lightning) and other weather phenomena. [28] Intense heat from a fire causes air to rapidly rise within the smoke plume, causing the formation of pyrocumulonimbus clouds. Cooler ...
Lightning currents have a very fast rise time, on the order of 40 kA per microsecond. Hence, although lightning is a form of direct current, conductors of such currents exhibit marked skin effect as with an alternating current, causing most of the currents to flow through the outer surface of the conductor.

Here's what to know about thundersnow: Winter snow storm: Fierce winter storm slamming Mid-Atlantic; DC could get a foot of snow Thundersnow observed in St. Louis during winter snow storm ...
A large squall producing heavy snow and frequent lightning over Buffalo, NY. Lake effect thundersnow occurs after a cold front or shortwave aloft passes over a body of water. This steepens the thermal lapse rates between the lake temperature and the temperatures aloft. A difference in temperature of 25 °C (45 °F) or more between the lake ...
The weather service also highlights that lightning “will travel through the wiring and plumbing if your building is struck.” If you are outside when the storm hits, “do not lie on the ground ...
A return stroke, cloud-to-ground lightning strike during a thunderstorm. Cloud-to-ground lightning frequently occurs within the phenomena of thunderstorms and have numerous hazards towards landscapes and populations. One of the more significant hazards lightning can pose is the wildfires they are capable of igniting. [54]
Single sensor lightning detectors have been used on aircraft and while the lightning direction can be determined from a crossed loop sensor, the distance can not be determined reliably because the signal amplitude varies between the individual strokes described above, [11]: 115 and these systems use amplitude to estimate distance. Because the ...
The view from Malibu, California, as a early morning monsoon storm moving north up the coast created a huge lightning show that could be seen from Orange County to Santa Barbara County on Friday ...
