Physics Which one of the following statements with regard to Jet stream, an upper level tropospheric wave, is not correct? Jet streams are typically continuous over long distances. In summer, the polar front jet achieves its maximum force. It is narrow band of high-velocity wind. It follows the wave path near the tropopause at elevations of 8 km to 15 km.
