Why does the jet stream in the Northern Hemisphere move north in the summer and south in the winter ?

Answer 1

The jet stream exists due to a large temperature gradient, or change in temperature with distance. It is located above the polar front, which separates warm subtropical air from cold polar air. The jet stream follows the polar front, which migrates south in the winter and north in the summer. The polar front stays in the same place relative to the sun, but since the sun is farther south during the winter, so is the polar front. This can be seen in surface temperatures in the midlatitudes. There is a large temperature gradient during the winter, in the summer it is weak because it is farther north.

Answer 2

When it's south that means that all of the cold weather shifts downwards into the south which makes it cold in the winter and then when it's north in the summer the jet stream prevents the cold air from sinking south so all of the warm air can come up northwards.

Answer 3

it is not lots that it shifts north or south yet that the land mass over which the Jet bypass extends transformations with the seasons. for the period of summer season that's constrained to the greater northerly lattitudes yet come summer season it extends greater south. the considerable driving force is temperature and by using the wintry climate months there's a lots greater desirable floor temperature assessment between the polar and tropical air a lot. through this the Jet bypass covers a greater robust area than it does in summer season while there's a lots lesser assessment. in many situations in wintry climate it lies between 40 and 80 stages north of the equator yet in summer season is constrained greater to between 40 and 50 stages north.

Answer 4

Probably the jet stream follows the sun's apparent movement.

Answer 5

because i want it, if its ok with you?
