Question

Westerly winds in the upper atmosphere at mid-latitudes in the northern hemisphere:

a. are a result of a pressure gradient that moves air from the poles toward the equator.
b. are stronger in summer than in winter.
c. are the reason most mid-latitude storms move from west to east.
d. are moving perpendicular to 500 mb contours.

Answer 1

Westerly winds in found in the upper atmosphere at 'mid-latitudes' in the northern hemisphere are the 'reason most mid-altitude storms' moves from 'west to east'.

Step-by-step explanation:

• Westerly winds are considered or known as the conclusion for directional movement of earth and also it also works on the circulation of atmosphere.

• The 'rotation of earth' is exactly at 1673 km /hr. There are basically four kinds of global wind which is known as easterly wind, planetary wind, Periodic wind and local winds.

Answer 2

The answer is C. These winds are called westerlies, intuitively because they blow from west to east. They are as a result of high pressure in the sub-tropical latitudes and blow towards the poles where there’s lower pressure. The winds are strongest in the winter and weakest in the summer.
