2021年9月15日 Cyclone Paths on Planet Earth Image Credit: National Hurricane Center, NOAA, NASA; Processing: Nilfanion (via Wikipedia) Explanation: Where on Earth do cyclones go? Known as hurricanes when in the Atlantic Ocean and typhoons when in the Pacific, the featured map shows the path of all major storms from 1985 through 2005. The map shows graphically that cyclones usually occur over water, which makes sense since evaporating warm water gives them energy. The map also shows that cyclones never cross — and rarely approach — the Earth’s equator, since the Coriolis effect goes to zero there, and cyclones need the Coriolis force to circulate. The Coriolis force also causes cyclone paths to arc away from the equator. Although long-term trends remain a topic of research,…

2020年9月10日 Jupiter’s Swimming Storm Image Credit & Copyright: Andy Casely Explanation: A bright storm head with a long turbulent wake swims across Jupiter in these sharp telescopic images of the Solar System’s ruling gas giant. Captured on August 26, 28, and September 1 (left to right) the storm approximately doubles in length during that period. Stretching along the jetstream of the planet’s North Temperate Belt it travels eastward in successive frames, passing the Great Red Spot and whitish Oval BA, famous storms in Jupiter’s southern hemisphere. Galilean moons Callisto and Io are caught in the middle frame. In fact, telescopic skygazers following Jupiter in planet Earth’s night have reported dramatic fast moving storm outbreaks over the past few weeks in Jupiter’s North Temperate Belt. Tomorrow’s…

2019 September 15 A Long Storm System on Saturn Image Credit: Cassini Imaging Team, SSI, JPL, ESA, NASA Explanation: It was one of the largest and longest lived storms ever recorded in our Solar System. First seen in late 2010, the above cloud formation in the northern hemisphere of Saturn started larger than the Earth and soon spread completely around the planet. The storm was tracked not only from Earth but from up close by the robotic Cassini spacecraft then orbiting Saturn. Pictured here in false colored infrared in February, orange colors indicate clouds deep in the atmosphere, while light colors highlight clouds higher up. The rings of Saturn are seen nearly edge-on as the thin blue horizontal line. The warped dark bands are the…
