There are different 'layers' of air at different heights and these can be affected by different conditions causing them to move in different directions. This is sometimes referred to as 'shear' or 'wind shear' and is most noticeable when there are cloud formations in each layer which can be seen moving in different directions.
Just like every other celestial object, the stars and their apparent patterns move from east to west in the sky as time goes on.
In this context, the sky doesn't move, but the earth rotates creating the illusion that the sky moves (unless you mean clouds which is a different issue altogether.). The sky appears to move from east to west.
The Moon travels across the sky in the same direction as the Sun; Its' leading edge is the point at which phase changes start and move from right to left.
Because it does
The moon goes in the direction of its orbit
Regulus stars appear to move across the sky from East to West (:
The patterns appear the same because the stars are so far away that their movement is not apparent to our eyes. They move across the sky because the earth is rotating and that makes it look like the stars are moving. Just like the sun does not move across the sky, the earth rotates and the sun appears to move, the same is with the stars.
Watch dragon heart
