Jet streams are fast-flowing, narrow air currents found in the upper atmosphere (tropopause and lower stratosphere) at altitudes of 8 to 15 kilometers (Statement B). They are characterized as narrow bands of high-velocity winds (Statement A) and extend continuously over long distances around the globe, although their path meanders in wavelike patterns (Statement C).
