WAVES ARE FOUND TO MOVE THE WHOLE PLANET

Did you know that the waves that roll in to greet you at the beach began their journeys thousands of miles away from you? And that they have a big impact on us all, no matter where we are on the planet?

While scientists have long studied the effect of atmosphere and wind on waves, they are now finding that the movement of waves impacts the atmosphere. 

Using “large eddy simulation,” 1st developed in the 1960’s by the National Center for Atmospheric Research, NCAR Sr. Scientist Peter Sullivan & team recently studied a range of waves moving into areas with light winds to gain insights into how wave movements impact  global weather and climate patterns.

Contrary to common belief, an estimated 75% of waves are not actually driven by local winds, but are generated by distant storms.

When wind blows over the ocean, it transfers its energy into the water, whipping up swells, creating waves. 

Groundswell refers to waves generated by storms far off the coast. Wind swell refers to waves formed by local winds, close to shore. Their combination is what can make surfers very happy in the best of conditions and can bring devastating destruction in the worst case scenarios.

Wind from storms in the middle of the ocean create waves on its surface. These waves then travel thousands of miles, moving away from the storm, headed towards beaches, where they are boosted by local light winds.

For example, wave conditions in most of the Indian, Pacific and South Atlantic oceans are dominantly influenced by the weather in the Southern Ocean, thousands of kilometres away.

Over a billion data points crunched in NCAR’s Yellowstone super-computing system. Check out the beautiful data visualization video, as NCAR software engineer Scott Pearse, demos VAPOR, a software tool he created to aid ocean, atmosphere, and solar researchers.

It shows how waves and atmosphere dance together, in reciprocal movements, showing how small waves impose a drag on air, while fast and big waves provide thrust, pushing the air forward. 

This new data will provide valuable insight into climate patterns and weather predictions, helping us to better manage life both at sea an on terra firma. 

NACR is managed by the University Corporation for Atmospheric Research (UCAR),  a consortium of more than 100 North American colleges and universities is focused on research and training in atmospheric and Earth system sciences. It is sponsored by the National Science Foundation.
