The circulation pattern discussed above is mainly true on the surface movement. The atmosphere, like the oceans, have differences throughout the air column which cause changing weather. For example, when warmer air lies above polar air it, causes wind to blow parallel to where they meet. This produces a "jet" of strong air on a continuous basis referred to as the "Jet Stream."
Atmospheric circulation is further complicated by the distribution of land and water masses on the surface of the Earth and the topography of the land. The oceans are the source of moisture and the elevation of the land surface helps control where moist air will rise. Climatic zones depend not only on latitude, but also on the distribution and elevation of land masses. In general, however, most of the world's desert areas occur along the mid-latitudes where dry air descends along the mid-latitude high pressure zones.
Jet streams occur in the Northern Hemisphere in the summer months. These jet streams for in tropical regions and flow from east to west.
They occur at the boundaries between the first, second, and third wind systems
No. The Jet stream is in the upper troposphere and extends somewhat into the lower stratosphere.
A jet stream occurs when warmer air lies above polar air.
The jet stream
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
a jet stream is important because of climate control
No. The Jet stream is in the upper troposphere and extends somewhat into the lower stratosphere.
Polar jet stream is stronger.
A jet stream occurs when warmer air lies above polar air.
The jet stream
A gulf stream is water ,and a jet stream is air.
The jet stream is located in the stratosphere.
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
mid latitude jet stream and jet stream
jet stream
No. The jet stream is in the upper troposphere and lower stratosphere.
The polar jet stream is generally stronger than the subtropical jet stream
The polar jet stream is generally stronger than the subtropical jet stream
