The weather that typically occurs in the middle latitudes is driven in part by the jet stream - a corridor of strong winds found 8-13 km above ground - and atmospheric undulations associated with ...

Rossby waves are fundamental components of the midlatitude atmospheric circulation, arising from the conservation of vorticity on a rotating planet. They appear as large-scale undulations in the jet ...

Winter is coming—eventually. And while the Earth is warming, a new study suggests that the atmosphere is being pushed around in ways that cause long bouts of extreme winter cold or wet in some regions ...

Rossby waves naturally occur in rotating fluids. Within the Earth's ocean and atmosphere, these planetary waves play a significant role in shaping weather. This animation from NASA's Goddard Space ...

Atmospheric Rossby waves might take several weeks to travel across North America, while oceanic Rossby waves take months to cross a basin. I’ve mentioned Rossby (planetary) waves in a number of posts.

From February to May 2022, many places in Queensland, New South Wales and Western Australia have seen record-breaking daily and monthly rainfall. Repeated periods of persistent and intense rain have ...
