  5. A New Hurricane • Once a storm’s sustained wind speeds reach 74 miles an hour it becomes a hurricane. • It’s given a name in alphabetical order and alternates between male and female names.

  6. The Coriolis Effect • The rotation of the Earth causes an phenomena on free moving objects on the Earth. • Objects in the Northern Hemisphere rotate to the right • Objects in the Southern Hemisphere rotate to the left. • The effect tries to force winds to shift towards the right or left. The effect can at times cause winds to blow back up the pressure gradient.

  7. Compared With a Hurricane Typhoons Cyclones Begin in the Southern Pacific. Not as prevalent as hurricanes because of the cold water temperatures. Often difficult to predict, as they can suddenly weaken or change their course. • Begins in the Western Pacific. • Endanger far less land area due to their locations. • Winds are usually stronger than a hurricane.
