It can be inferred from the passage that during yearly equinoxes, jet streams tend to
A．move at velocities slower than those at which they move the summer but faster than those at which they move in the winter
B．move from toward the east from the west in accordance with the deflection process caused by the Coriolis force
C．move at velocities faster than those at which they move the summer but slower than those at which they move in the winter
D．move at velocities equal to those of other planets that have similar polar temperature gradients
E．move at velocities equal to that of the centrifugal motion that causes the deflection of the jetstream"s direction请帮忙给出正确答案和分析，谢谢！
