This progress is caused ~ the

stant movement Of the ataosphere

This. Of course. does not mean
that the wind always blows fson the
west. The great current flows in
that direction. but surface coaditions
cause Innumerable eddies which are
the winds we feel. Into . low pres
sure area. for instance. the air
rushes from every direction. Thus.
II the center OF the disturbances is to
the west OF us. we will have an east
erly wind ms the air rushes toward
this center: when the storm has
reached and passed us on it, easter
ly way We will have westerly81nds.
For this reason Il Is common 70 say
that west winds mean clear Weather

In regard to tempsratare. every

means warm weather. in summer
cool weather. This arises from The
fact that heat travels mor~ eosily
through clear skies than throNgh
clouds and moisture. In the DAY.
