Which jet stream affects weather in New Mexico?
a. the northern subtropical jet stream
b. the southern subtropical jet stream
c. the northern midlatitude jet stream
d. the southern midlatitude jet stream
New Mexico is in the Northern Hemisphere, so the jet stream will also be northern: we can reject the options with southern Jet Stream, that is B and D.
Now, the midlatitude is also called polar jet stream - and it's further north.
The correct answer is a.-the northern subtropical jet stream
