Answer:
A:They blow slower
Step-by-step explanation:
Jet streams are cold massive moving amount of air which blows from west to east due to the earth's rotation, and wide variation in the cold and warm air. During winter, jet streams are pronounced and blows at a high speed.
The equator is a the circumference on the earth's surface which divides the earth into two equal hemispheres. When jet streams get closer to the equator, there is a decrease in the rate at which it blows. Thus, they blow slower on moving closer to the equator of the earth. At the equator, there is no jet streams that could be observed.
