The aurora is expected to be bright and visible in multiple northern U.S. states Oct. 3 through Oct. 5 as well as from the lower Midwest to Oregon.
This is due to high moisture content in the lower atmosphere and high surface temperature, which produces strong sea breezes along the Florida coast. [5] As a result, heat lightning is often seen over the water at night, the remnants of storms that formed during the day along a sea breeze front coming in from the opposite coast.
Typically, lightning discharges 30,000 amperes, at up to 100 million volts, and emits light, radio waves, x-rays and even gamma rays. [1] Plasma temperatures in lightning can approach 28,000 kelvins. Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet).
Sprites or red sprites are large-scale electric discharges that occur in the mesosphere, high above thunderstorm clouds, or cumulonimbus, giving rise to a varied range of visual shapes flickering in the night sky. They are usually triggered by the discharges of positive lightning between an underlying thundercloud and the ground.
We also see the Rayleigh effect at play in: -Sunsets where the sky is red.Light has to pass through a larger part of the atmosphere when the sun is lower on the horizon. Red, orange and yellow ...
“The average lightning bolt carries about 30,000 amps of charge, has 300 million volts of electric potential, and is about 50,000°F,” the National Weather Service says. Lightning bolt hits ...
This temperature inversion is the opposite of what is normally the case; air is usually warmer close to the surface, and cooler higher up. In calm weather, a layer of significantly warmer air can rest over colder dense air, forming an atmospheric duct which acts like a refracting lens, producing a series of both inverted and erect images.
The northern lights made a rare appearance in the Massachusetts sky last night, treating sky-gazers to a colorful display that usually only appears further north.. The unusual showing was due to a ...
