  1. GLOBAL CLIMATE POWERFUL STORMS

  2. POWERFUL STORM • Tropical storms : a storm originating in the tropics and marked by high winds and often heavy rain, such as hurricanes, cyclones, and typhoons. • The atmosphere is in continual motion, with swirling masses of air that create our weather. This movement of air masses happens for two reasons - • 1 – the earth is spinning in its daily rotation • 2 – the earths surface is unevenly heated

  3. POWERFUL STORMS

  4. TROPICAL STORMS • From the map, you can see that hurricanes, cyclones, and typhoons all begin in oceans on each side of the equator. • From there, they sweep toward the mid-latitudes, sometimes reaching as far as Nova Scotia. • These tropical storms originate from warm ocean waters. • “think of them as swirling mountains of warm, moist air heated by the sun’.

  5. TROPICAL STORMS • As a mound of warm air rises from the ocean surface, cooler air blows into the base of the air mass. A tropical disturbance is set up. • As the new air is heated and rises, the tropical disturbance grows larger and spins faster. • It is upgraded to hurricane status. • The suns energy is responsible for tropical storms. North America could be powered for half a year on the energy of one hurricane season!
