Web1 jul. 2024 · Clear air turbulence, or CAT, is especially problematic as it occurs in, well, clear air. This means that, as opposed to a cloud, it is impossible to detect with the naked eye and extremely difficult to pick up using radar equipment. CAT is generated by instabilities in the jet stream because of very fast air currents at 35,000 feet. Web28 aug. 2024 · A jet streak is an area of much faster winds within the jet stream itself.

Web30 jan. 2024 · Jet streams are currents of air high above the Earth. They move eastward at altitudes of about 8 to 15 kilometers (5 to 9 miles). They form where large temperature differences exist in the atmosphere. Cooler, heavier air then pushes in to replace the warm air, forming a cool air current. Why are jet streams faster in winter? WebThis figure examines a particularly strong jet stream and the eddies that drive it through the atmosphere of Saturn's northern hemisphere.
