The main causes of wind on the Earth are the Earth's rotation and the heat from the sun falling unevenly on the Earth's surface.
As the air warms, it rises. Air moves in to fill the low pressure. Since the Earth is a spinning sphere, the air begins to spin as well. In the Northern Hemisphere the spin is counter-clockwise. In the Southern Hemisphere the spin is clock-wise. The general direction of large storms is from East to West since they are in the air and the Earth is rotating under them in a West to East direction. But pressure drives all storms and when the pressure drives them East, then they will go East. Or West or North or wherever the pressure guides them.
The Northern and Southern Jet streams are a result of the Earth's spin, not the Sun's heat. They must follow after the Earth so they move from West to East, the same direction as the Earth's spin, but they are affected by other pressures and can twist and turn from a northerly direction to a southerly one and all in between. But they are like necklaces around the Earth and must complete their paths eventually.
;-D Let's go sailing or flying kites! The wind is just right today!

The jet stream is different from "the wind" which can blow in any direction. Generally, the jet stream goes from west to east, but it can veer north and south, and has been known to go slightly in the opposite direction depending on extreme weather like hurricanes and other very high and very low pressure systems.

You're in the northern hemisphere. The winds are different in different "latitudes" of the earth. Ours go west to east. The jet stream may dip now and then, but it stays the same. Jet streams in other parts of the world- their direction depends on where it's located. Further south, it goes east to west- like where tropical storms and hurricanes that affect the U.S. are generated- off the coast of Africa.

The jet stream (as you know it) always goes from West to East. This is due to the rotation and shape of the Earth. It sometimes swings to the South and sometimes further North, but always West to East.

You should have said why does wind blow MOSTLY west to east. It does change. A lot has to do with where you live. Most of the US has west to east winds because of the earth's roatation. However, when a low pressure system is off to your east it can make the winds blow S to N or N to S or E to W.....E to W usually means a change in the weather....i.e. colder or hotter weather. Hope this answers your question. Best wishes.

The jet stream is waaaay up high -- about 20,000 feet high. Here in the Northern hemisphere they do trend generally eastward. But local winds are a different phenomenon, and they can flow in any direction. Then there are onshore and offshore winds, downslope winds the venturi effect from local topography and so on. So the short answer is no.

The jet stream changes direction all the time, coming south and moving north.

Jet stream stays same, wind can change.
Storms can come from east, west, north, or south.
Depends more on pressure in areas, and moisture ahead of pressure.

Geography plays a part in moving the jetstream, but it travels from the west to the east over the USA

Hurricanes/tropical systems are examples of storms that can move from east to west and from south to north.
