The phenomenon where the the earths rotation manipulates the travel of free moving substances across earths surface.
A wind from the direction that is predominant at a particular place or season.
A narrow, variable band of very strong predominantly westerly air currents encircling the globe several miles above the earth. There are typically two or three jet streams in each of the northern and southern hemispheres.
How are weather patterns affected? (+Maps)
Influences winds by deflecting their path to the right in the northern hemisphere. This makes storms arc northwards in a parabola-like fashion. In the south, it does the same thing but southwards.
Wind can greatly affect the amount of precipitation an area receives depending on on the amount of moisture they are carrying. The prevailing winds can move air masses from the ocean into a continent bringing moisture into that area.
The two jet streams that directly affect our weather in the continental US are the polar jet and the subtropical jet. They are responsible for transporting the weather systems that affect us.
