WebAug 6, 2024 · The jet stream is a core of strong winds around 5 to 7 miles above the Earth’s surface, blowing from west to east. The jet stream may also change the effectiveness of a place of low pressure. It functions similar to a vacuum, sucking air from the top and causing it to get more serious, decreasing the pressure system. WebNote first that the chart has a very similar geometry, meaning the troughs and ridges are in basically the same location as they are on the 500 mb chart, as is the jet stream (this occurs in all cases, allowing you to infer positions of jet streams and troughs and ridges in the upper troposphere simply by looking at a 500 mb chart).
