How do hurricanes and tornadoes form?
What will be an ideal response?
Many changes in weather occur when air masses with different physical properties meet. If air behind a cold air mass rises over a warm air mass, sometimes the warm air rises quickly, setting a powerful convective current in motion. If high-altitude winds are blowing faster than and in a different direction from lower winds, a rising column of air, a tornado funnel, may begin to rotate. In the Northern Hemisphere, the Coriolis effect causes the winds to turn counterclockwise. In the case of hurricanes, winds move rapidly into an area of low pressure where warm moisture-laden air over oceans is rising. In the Northern Hemisphere, the Coriolis effect causes the winds to rotate counterclockwise. As more and more water is drawn into the rotation, heat from evaporating water adds force to the circulation. In North America, the Gulf and Atlantic Coasts with their warm surface waters are susceptible to hurricanes.
