Riding a motorcycle off-pavement is one of the greatest thrills you can experience without stepping into a flight deck or taking a car past 100 mph. Take a bike onto a fire road and you’ll know ...

When a volcano erupts, it can spew ash high into the atmosphere—inserting aerosols right where clouds typically form. How ...

When the wind blew from the direction of the colony, ammonia levels spiked, sometimes reaching 1,000 times above normal ...

Matthew Boyer, an atmospheric scientist at the University of Helsinki, and colleagues wanted to assess how this natural fertilizer might be affecting cloud formation in the region. The researchers ...

Volcanic ash from eruptions can reshape cirrus clouds, forming giant ice crystals and altering how Earth traps heat in the ...

Weather officials say different types of clouds can tell you what kind of weather to expect. Here's a look at the different types.

Specifically, ammonia released from penguin poop (aka guano) may help to reduce the effects of climate change in the Antarctic by contributing to increased cloud formation, according to a new ...

That warm air is forced upward, cools rapidly, and condenses into a low, horizontal cloud formation. This process creates the classic shelf cloud—broad, arching, and often layered like a stack ...

Eos offers a rare opportunity to study molecular cloud formation and dissipation up close. It also helps reveal how much interstellar material is available near our sun for forming stars and planets.

Biological particles like pollen, bacteria, spores and plant matter floating in the air are particularly good at promoting ice formation in clouds, and EPFL climate scientists show that these ...
