Gravity Waves in the Sky

Gravity waves are global events. Much like the ripples on a massive pond, these large-scale waves can propagate from an atmospheric disturbance over thousands of miles

Like waves in the ocean, these gravity waves roll through the sky. Caused by frontal systems, air flowing over mountains, and other reasons. these waves can travel thousands of miles through atmosphere.

What is interesting is that these waves may be a cause of tornadoes. The ability to track these gravity waves could help us predict severe weather outbreaks with more precision. These are beautiful, frightening things.
