A Rendering (Motion Edit) Of A Thunderstorm, Based On A Single Photograph Of A Cumulonimbus Cloud Lit

Dirty thunderstorm

A dirty thunderstorm (also volcanic lightning, thunder volcano) is a weather phenomenon that is related to the production of lightning in a volcanic plume.

A study in the journal Science indicated that electrical charges are generated when rock fragments, ash, and ice particles in a volcanic plume collide and produce static charges, just as ice particles collide in regular thunderstorms.

Volcanic eruptions are sometimes accompanied by flashes of lightning. However, this lightning doesn’t descend from storm clouds in the sky. It is generated within the ash cloud spewing from the volcano, in a process called charge separation.

Incredible south pole aurora of Saturn

this storm season started off so poorly for me but the last week has been one of the best weeks of my life. life is weird like that. 

Betelgeuse is still there, but had to check

Video Clip SS2935432 (Supercell Thunderstorm, timelapse)

Timelapse footage of a Supercell thunderstorm with multiple lightning flashes. 

A supercell is a large rotating storm system that often produces heavy rain, hail and sometimes tornadoes. The supercell is centred on a very powerful updraft, which lifts warm, moist air to high altitude. It cools as it rises, condensing and falling as precipitation. 

The base of the cloud is marked by a shelf cloud extending forwards, and a low wall cloud at the updraft/downdraft interface. This supercell was filmed in Kansas, USA, in June 2015. Such storms are most common in this region in spring and early summer.

Supercells are often put into three classification types: Classic, Low-precipitation (LP), and High-precipitation (HP). LP supercells are usually found in climates that are more arid, such as the high plains of the United States, and HP supercells are most often found in moist climates. 

Supercells can occur anywhere in the world under the right pre-existing weather conditions, but they are most common in the Great Plains of the United States in an area known as Tornado Alley and in the Tornado Corridor of Argentina, Uruguay and southern Brazil.

The Size of the Sun As Seen From Each Planet

Hurricane Florence

Hurricane Florence wide-angle ESA astronaut Alexander Gerst took this image of Hurricane Florence on 12 September 2018, 400 km high from the International Space Station. He commented: “Watch out, America! Hurricane Florence is so enormous, we could only capture her with a super wide angle lens from the International Space Station, 400 km directly above the eye. Get prepared on the East Coast, this is a no-kidding nightmare coming for you.” Alexander is on his second six-month Space Station mission.
