The troposphere
Trade winds are found in the tropics in the lower section of the troposphere near the Earth's equator. The trade winds blow predominantly from the north-east in the Northern Hemisphere and from the south-east in the Southern Hemisphere.
Asthenosphere-Upper mantle Lithosphere-Upper mantle & lower crust Troposphere-Low air sphere Stratosphere-Higher air sphere
Surface winds have to flow around such things as buildings and mountains. Upper-level winds have no 'obstructions' to alter their path.

jetstreams
Jet streams are found in the upper troposphere - these are high velocity air flows that follow a curved path moving west-to-east around the globe.Narrow belts of strong winds are called jet streams. Jet streams blow near the top of the troposphere. The thin layer of air that surrounds the Earth is called the atmosphere.
Jet Streams
The Jet Stream.
JET Streams.The winds of the upper troposphere are quite different from the winds in the lower troposphere.They are stronger and blow in a different direction, mostly out of the west
The streamers of cirrus clouds have strong winds that often blow streamers. The features show the direction of the wind in the upper Troposphere.
The troposphere
No. The jet stream is in the upper troposphere and lower stratosphere.
It is called the TRADE WINDS.
