Explosions help probe elusive atmospheric waves

Infrasound waves can probe some of the most complex weather patterns hidden to normal observations, but finding a powerful enough source of infrasound waves can be a challenge unless there is a munitions factory nearby.

Tonga eruption: we are watching for ripples of it in space

The ongoing volcanic eruption in Tonga began in December 2021, but it wasn't until 5:15pm local time on January 15 2022 that the powerful explosion occurred. It generated an enormous cloud of ash, earthquakes, and tsunamis ...

Gravity wave insights from internet-beaming balloons

Giant balloons launched into the stratosphere to beam internet service to Earth have helped scientists measure tiny ripples in our upper atmosphere, uncovering patterns that could improve weather forecasts and climate models.

Waves in thin air with broad effects

Mars has a very thin atmosphere, with nearly one hundredth the density of ours on Earth, and gravity pulls with little more than one third of the strength we feel on our planet. As a result, dust storms can go global. For ...

NASA balloon mission captures electric blue clouds

On the cusp of our atmosphere live a thin group of seasonal electric blue clouds. Forming 50 miles above the poles in summer, these clouds are known as noctilucent clouds or polar mesospheric clouds—PMCs. A recent NASA ...

NASA solves how a Jupiter jet stream shifts into reverse

Speeding through the atmosphere high above Jupiter's equator is an east-west jet stream that reverses course on a schedule almost as predictable as a Tokyo train's. Now, a NASA-led team has identified which type of wave forces ...

Venus's turbulent atmosphere

Venus is often referred to as Earth's twin because both planets share a similar size and sur-face composition. Also, they both have atmospheres with complex weather systems. But that is about where the similarities end: Venus ...
