What is a leaping sundog?

Firstly, a sundog is an atmospheric optical phenomenon where bright spots appear on either side of the Sun. In terms of “jumping” sundogs, scientists hypothesize that a lightning… More. The new electric field quickly re-orients the crystals causing an appearance of “jumping” light.

What is flashing in cloud?

Cloud flashes sometimes have visible channels that extend out into the air around the storm (cloud-to-air or CA), but do not strike the ground. The term sheet lightning is used to describe an IC flash embedded within a cloud that lights up as a sheet of luminosity during the flash.

What causes crown flashes?

The most likely explanation is that crown flash is caused by changing electrical fields within the thundercloud, to which plate- or needle-shaped ice crystals align, preferentially reflecting sunlight.

How does crown flash work?

It’s actually a crown flash, which occurs when ice crystals in high clouds all line up to focus and reflect sunlight into a pillar-like shape. Then when the ice crystals change their orientation quickly, the pillar appears to dance, or even dissipate entirely.

What causes crown flash?

How tall do Thunderstorms get?

40,000 to 60,000 feet
Mature thunderstorms often reach 40,000 to 60,000 feet, and it is not unheard of to see thunderstorms reach upward of 75,000 feet in the tropics. Generally the taller the thunderstorm is, the more intense and dangerous its sensible weather are.

What is fire lightning?

a brilliant electric spark discharge in the atmosphere, occurring within or between clouds, or between a cloud and the ground.

What is a crown flash?

An extremely rare meteorological phenomenon, crown flash, was first scientifically described in the journal Monthly Weather Review in 1885. It can occur at the top of thunderstorms and appears as a bright patch of sky not dissimilar to a sundog.

What causes crown flash in clouds?

Unlike a typical sundog, however, these features move and realign within seconds, forming beams and loops of light. The most likely explanation is that crown flash is caused by changing electrical fields within the thundercloud, to which plate- or needle-shaped ice crystals align, preferentially reflecting sunlight.

What is the meaning of a clearcrown flash?

Crown flash is a rarely observed meteorological phenomenon involving “The brightening of a thunderhead crown followed by the appearance of aurora-like streamers emanating into the clear atmosphere”.
