The sub-tropical jet stream is produced by the earth’s rotation (Coriolis force) and temperature contrast between tropical and sub – tropical regions.At the equator, the rotation produces greatest velocity in the atmosphere. As a result, the rising air which spreads out northwards and southwards, moves faster than the latitudes over which it is blowing.It is deflected to the … Read more DMPQ-Subtropical Jet streams.
