1. Describe what changes between January, April, July, and October.
In January, a continuous, circular jet stream goes from Africa to the west coast of North America until it splits up into two S shaped streams (one over Africa and one over the ocean between Asia and North America). A distinct ridge and trough develops over North America. Depending on the day of the month, there is a trough, continuous jet stream, or broken up jet stream over the ocean between North America and Africa.
In April, the jet stream from Africa to the west coast of North America seems more fragmented and less circular with troughs and ridges. Over North America, there’s either a longer lasting ridge or trough, but fragmented a lot.
In July, the jet stream is mostly split into small …show more content…
Over North America, there’s a ridge and/or trough. 2. How do the jet stream maps in the Southern Hemisphere in January and July compare to the Northern Hemisphere jet stream in January and July?
In January the Southern Hemisphere jet stream is more wavy with troughs and ridges while the Northern Hemisphere jet stream is more circular or S shaped over Africa to the western coast of North America. The Northern Hemisphere jet stream from the eastern coast of North America to Africa is wavier with troughs and/or ridges is more like the Southern Hemisphere jet stream with the same shape.
The jet stream in July in the Northern Hemisphere and Southern Hemisphere are both generally wavy with ridges and troughs. However, Northern Hemisphere jet stream is much more fragmented and the streams are narrower than the Southern Hemisphere jet streams that are more continuous and larger width wise.
3. On what dates of this week do you see a major trough (u-shape) over the southwestern U.S.?
I see a trough over the southwestern US on December
