What causes lightning? Lightning originates from thunder cells with a diameter of several kilometers. Positively and negatively charged areas are created because of a choppy ice and water distribution, similar to updraft and downdraft winds within the cloud. If the voltage variations become too immod...

Lightning is a naturally occurring phenomenon that releases one gigajoule of energy because of electrostatic discharge. There are three types of lightning: cloud to ground, cloud to air, and cloud to cloud. Answer and Explanation: Learn more about this topic: ...
After having discovered the slight sensitivity of the model to the exact point position, the obtained density surfaces for the two causes were combined to discover hotspot areas and spatial patterns of the two causes. Evident differences in spatial location of the origin causes were noted and ...
In a new study, scientists have proposed that volcanic lightning may have played a pivotal role in sparking the origin of life on Earth. This phenomenon, characterized by intense electrical discharges during volcanic eruptions, could have fixed atmos... ...
Lighting originates when wind updrafts and downdrafts take place in the atmosphere, creating a charging mechanism that separates electric charges in clouds – leaving negative charges at the bottom and positive charges at the top. As the charge at the bottom of the cloud keeps growing, the ...
Heinz Kasemir first hypothesized that a lightning leader system actually develops in a bipolar fashion, with both a positive and a negative branching leader system connected at the system origin and containing a net zero charge. This process provides a means for the positive leader to conduct away...
when increasing the CSS in such clouds from the lowest to the highest third of CSS concentrations causes a warming in CTT (Fig.3a) and a decrease in lightning (Fig.3d). The decrease in lightning is greatest (×0.2) for the largest amount of fine aerosols, because the CSS can restore mo...
