Westerly jet stream drives clouds and above normal temperatures by: Paul Dailey, Jennifer Kohnke. Posted: Dec 6, 2022 / 10:23 PM CST. Updated: Dec 6, 2022 / 10:30 PM CST.

The subtropical westerly jet is a high-altitude, fast-moving air current that flows from west to east in the subtropical region of the Earth's atmosphere. It's an important part of atmospheric ...

A new study suggests that about 72% of the subtropical westerly jet's northward movement is because of changes in temperature, while about 28% is due to swirling air patterns. The shift ;likely ...

The jet is the North American westerly jet, a strong and narrow belt of wind. The study found that future mean precipitation during the Midwest rainy season will not change significantly relative ...

Meanwhile that wet (and warm) westerly jet running into California gives them a wetter than normal winter. Remember this is all what is “typical”.

They found that extratropical ocean-atmosphere coupling enhances teleconnection patterns and causes more meandering westerly jet streams, which are linked to extreme weather events.
