This Hole in the Sky Is Called a Fallstreak or Hole Punch CloudI prefer the latter name, as it more imaginatively describes what we're seeing: as though someone cut a hole out of the cloud formation. Earth Science Picture of the Day explains how it forms:Hole punch clouds can occur following cloud seeding, but they're almost always caused by aircraft passing through a shallow, mid-level cloud deck. They're not often seen but can be attention getting whenever they form. If the supercooled water droplets in the cloud layer are perturbed during a jet or propeller plane transit, the droplets will instantly freeze into myriad ice crystals. When this happens latent heat is released which warms the air and evaporates the undisturbed portion of the cloud. Ice crystals falling through the hole punch (the darkened patch near the center of the hole) are called fall streaks.-via TYWKIWDBI | Photo: H. Raab#cloud #holepunchcloud

The Bootleg Wildfire in Oregon is So Large It's Creating Its Own WeatherThe Bootleg fire in Oregon, which has been burning since July 6, has burnt more than 606 square miles - an area larger than Los Angeles. The fire has now become so intense that it has created its own weather.A satellite image posted by the National Oceanic and Atmospheric Administration showed the tremendous amount of smoke that the fire generated.Fire officials noted that the Bootleg fire has shown “aggressive surface spread with pyrocumulus development.”  Pyrocumulous clouds or flammagenitus clouds are formed by intense heating of the air from the surface due to volcanic eruptions or forest fires. The intense heat causes the air mass to rise, then moistures to condense on ash particles essentially becoming their own thunderstorms, complete with lightning and strong gusts of wind.The fire is "so large and generating so much energy and extreme heat that it's changing the weather," Marcus Kauffman said to CNN. "Normally, the weather predicts what the fire will do. In this case, the fire is predicting what the weather will do."#fire #wildfire #smoke #cloud #PyrocumulousCloud #FlammagenitusCloud #ForestFire #BootlegFire #weather

NASA Found Derpy Face on Jupiter, Named It "Jovey McJupiterface"NASA's robotic Juno spacecraft has captured the face of Jupiter, which NASA has lovingly named "Jovey McJupiterface."APOD explains what we're seeing:What do you see in the clouds of Jupiter? On the largest scale, circling the planet, Jupiter has alternating light zones and reddish-brown belts. Rising zone gas, mostly hydrogen and helium, usually swirls around regions of high pressure. Conversely, falling belt gas usually whirls around regions of low pressure, like cyclones and hurricanes on Earth. Belt storms can form into large and long-lasting white ovals and elongated red spots.#Jupiter #cloud #NASA #JunoSpacecraft #JunoCam #spaceHere's the full pic:
