“Meteorological Beast in Our Solar System” – Powerful Stratospheric Winds Measured on Jupiter for the First Time
Posted by Genevieve Klien in categories: climatology, space
“The most spectacular result is the presence of strong jets, with speeds of up to 400 meters per second, which are located under the aurorae near the poles,” says Cavalié. These wind speeds, equivalent to about 1450 kilometers an hour, are more than twice the maximum storm speeds reached in Jupiter’s Great Red Spot and over three times the wind speed measured on Earth’s strongest tornadoes.
“Our detection indicates that these jets could behave like a giant vortex with a diameter of up to four times that of Earth, and some 900 kilometers in height,” explains co-author Bilal Benmahi, also of the Laboratoire d’Astrophysique de Bordeaux. “A vortex of this size would be a unique meteorological beast in our Solar System,” Cavalié adds.

Lightning strikes played a vital role in life’s origins on Earth: study
Posted by Saúl Morales Rodriguéz in category: climatology
Lightning strikes were just as important as meteorites in creating the perfect conditions for life to emerge on Earth, geologists say.
Minerals delivered to Earth in meteorites more than 4 billion years ago have long been advocated as key ingredients for the development of life on our planet.
Scientists believed minimal amounts of these minerals were also brought to early Earth through billions of lightning strikes.

Nikola Tesla Predicted that the Weather Could Be Controlled and He Was Right
Posted by Prem Vijaywargi in categories: climatology, geoengineering
More than 100 years ago in his autobiography, Nikola Tesla reflected on the first time he had the idea to control the weather. Now, China is spending billions to prove that weather modification is possible.

Rookie numbers we can doom ourselves far faster, but we probably wont because survived at least 6 mass extinctions and that drive probably wont change with level of tech we have now.

The first known space hurricane pours electron ‘rain’
Posted by Brent Ellman in categories: climatology, space
Satellite observations have revealed an unprecedented ‘space hurricane’ in Earth’s upper atmosphere, hinting that such events could occur on other planetary bodies.
Scientists have previously documented hurricanes in the lower atmospheres of Mars, Jupiter and Saturn. Similar phenomena have even been spotted on the Sun. But the existence of space hurricanes — hurricane-like circulation patterns in planets’ upper atmospheres — has been uncertain.
Earth’s upper atmosphere cooks up a storm.

‘Space hurricane’ spotted above Earth for the first time ever
Posted by Genevieve Klien in categories: climatology, space
A first-ever “space hurricane” was spotted whirling above the Earth, scientists said.
The 600-mile-wide mass of plasma occurred several hundreds of miles above the North Pole, according to a study in the journal Nature Communications.
“Until now, it was uncertain that space plasma hurricanes even existed, so to prove this with such a striking observation is incredible,” said Mike Lockwood, a space scientist at the University of Reading and co-author of the study, in a statement.

Scientists confirm existence of space hurricanes for the first time
Posted by Alberto Lao in category: climatology
A space hurricane is confirmed for the first time in Earth’s upper atmosphere following observations of a swirling mass of plasma. Experts say such storms could disrupt GPS systems.
