Clouds over the Highest Mountains Dance a Little Differently

by Rebecca Dzombak 16 October 202616 October 2026

Clouds over the Tibetan Plateau and the Andes are growing colder and higher than other clouds in response to climate change. That could affect local hydrology and radiation.

The Effects of Polar Night and Day on Arctic Air Masses

by Manfred Wendisch, Matthew D. Shupe, Susanne Crewell, Felix Ament and Gunilla Svensson 16 September 202616 September 2026

Cold air outbreaks and warm air intrusions link Arctic and midlatitude weather and climate. But a lack of data on these events, especially in winter, limits our understanding.
