Scientists have sussed out a new source for the seeds of clouds. When the stratospheric layer of Earth’s atmosphere dips a toe into the underlying troposphere, the resulting chemical mixture ...

This texture is formed by closed-cell convection when the warmer air rises in the center of smaller cloud pockets. As on Earth, this warmer air forms the clouds, but on Mars the rising air ...

JACKSONVILLE, Fla. – The sun’s warming rays met less resistance in 2023, as Earth experienced a record low in cloud cover. Planetary albedo is how much sunlight is reflected into space by ...

Called noctilucent clouds (meaning "night-shining" clouds in Latin) or NLCs, these strange-looking patterns in the sky are the highest, driest, coldest and rarest clouds on Earth, according to a ...

Alexandria Johnson does hard science on the most nebulous of subjects: clouds. As an atmospheric scientist and assistant professor of practice in Purdue University’s College of Science, she studies ...
