Atmospheric instability has two components: rising air and wind shear, which is created as wind speed changes with height. The rising air, ...

Atmospheric instability is a key ingredient for hurricane formation. It occurs when warm, moist air rises and cools, creating ...

In addition to moving slower, future hurricanes are expected to dump a lot more rain. A study by scientists at the National Center for Atmospheric Research this year looked at how 20 Atlantic ...

Lightning requires atmospheric instability, something that’s set up when cold, parched air sits atop warmer, wetter air. At very high latitudes, that hotter, damper air tends not to show up.

Thundersnow is exactly what the name suggests – a snowy thunderstorm. But the winter version of a thunderstorm is far less frequent than the spring and summer thunderstorms most people are used to.

While the impacts of climate change vary across the globe, most scientists agree that, overall, a warming environment is increasing both the frequency and intensity of severe weather events such ...

Instability in the atmosphere often comes from differences in temperature and air density, which in turn fuels strong columns of rotating air within storms.
