In winter, the northern hemisphere upper-level westerlies are __ and extend further __
than in summer - ANS>>stronger, south
Short waves typically have __ divergence associated with them and move __ than long
waves - ANS>>more, faster
Flying at 35,000 ft, I am most likely to be in or above cloud when the wind is -

In January, strongest flow at 30,000 ft is found - ANS>>just east of Asia and N. America
The area of low upper-level heights (pressure) above the polar regions is called the -
ANS>>polar vortex
On average, maximum winds (jet streams) at 60N are found at __ altitude than those at
30N - ANS>>a lower
, On average, the westerlies __ with height in the troposphere and __ with height in the
stratosphere - ANS>>increase, decrease
A strong 300 mb polar jet is located across the GA/FL border. In Atlanta north of the jet,
I would expect - ANS>>colder than normal temperature
On average, the polar jet stream is located at ___ ft near latitude ___ - ANS>>30,000,

Compared with the north, the SOUTH side of an upper-level westerly jet has a ___
troposphere and a ___ tropopause height - ANS>>warmer, higher
Flying south to north across a westerly jet maximum, I would find the topopause getting
___ and the stratosphere getting ___. - ANS>>lower, warmer
