1. One of many driving forces of this weather (besides El Niño, NAO, PDO, etc.) might be the jet stream’s interaction with the Arctic Ocean.
2. The Arctic is warming at twice the rate of the rest of the world, partly because the sea ice is melting, allowing the sun to warm up the ocean water.
3. But more open water means more evaporation and clouds. Will more clouds act as cooling sun umbrellas, or warming blankets in the future? NASA’s new ARISE mission onboard the flying C-130 laboratory will look for some answers this coming September.

Every summer the Arctic ice cap melts down to what scientists call its \"minimum\" before colder weather builds the ice cover back up.

Deep troughs and steep ridges emerge as the denser cold air sinks and deflects warm air regions north, giving the jet stream its wavy appearance. This pattern propagates across the mid-latitudes of North America, Europe and Asia, as pockets of cold air sporadically creep down from the Arctic - creating contrasting waves and flows that accelerate eastward due to Earth's rotation. Running from June 10 to July 8 of 1988, the visualization below uses weather and climate observations from NASA's MERRA dataset to model nearly a month of the jet stream's whirling journey over North America. || ", "release_date": "2011-10-03T00:00:00-04:00", "update_date": "2025-03-17T00:01:14.231989-04:00", "main_image": { "id": 483187, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a003800/a003864/jetstream.00600.jpg", "filename": "jetstream.00600.jpg", "media_type": "Image", "alt_text": "Polar JetThis video is also available on our YouTube channel.", "width": 1280, "height": 720, "pixels": 921600 } } ], "products": [], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
