Think about it this way. If it was flat then jet streams would be straight. But the Earth is round so jet streams are curved because of the curvature of the Earth.
The jet stream
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
a jet stream is important because of climate control
It is false that a plane flying against a jet stream will travel faster than a plane traveling with a jet stream.
The polar jet stream is generally stronger than the subtropical jet stream
stream channel
A meander is a curve or bend in a stream or river.
A curve in the road is a bend. If the bend is very severe, it is a hairpin-bend.
The jet stream
curve means Bend
The polar jet stream is generally stronger and faster-moving than the subtropical jet stream. The polar jet stream forms at higher latitudes and is located closer to the poles, while the subtropical jet stream is located at lower latitudes. The polar jet stream is associated with larger temperature contrasts and stronger pressure gradients, resulting in stronger winds compared to the subtropical jet stream.
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
A curve in a stream channel is called a meander. Meanders are caused by the flow of water eroding the outside of a bend and depositing sediment on the inside, leading to a winding pattern in the channel. Meanders are a natural feature of rivers and streams and play a vital role in shaping the landscape.

The polar jet stream is generally stronger than the subtropical jet stream
No. The jet stream is in the upper troposphere and lower stratosphere.
