b) Rossby waves — Jet stream
c) Hadley cell — Mid-latitude cell
d) Index cycle — Walker circulation
Answer »Answer: (b)
Jet streams are fast flowing, narrow, meandering air currents found in the atmosphere of some planets, including Earth.
On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east).
Their paths typically have a meandering shape. Jet streams may start, stop, split into two or more parts, combine into one stream, or flow in various directions including opposite to the direction of the remainder of the jet.
The strongest jet streams are the polar jets, at 9–12 km (30,000–39,000 ft) above sea level, and the higher altitude and somewhat weaker subtropical jets at 10–16 km (33,000–52,000 ft).
