TODAY’S KEY IDEA: Energy enters the Earth system primarily as solar radiation and eventually escapes as heat.

  • Final Exam
    • P2: 12/19 Wednesday
    • 1 hour Final Examination
    • ½ hour Chapter 20 Weather Exam

SECONDARY IDEAS:

  • Weather is caused by warmer air interacting with cooler air.
  • Convection currents are caused by less dense air rising and more dense air sinking to fill in the “hole”.
  • Warmer air is LESS DENSE than cooler air.
  • Less dense matter “floats” on top of more dense matter.

Hurricanes

A Hurricane is a large rotating storm of tropical origin that has sustained winds of at least119km/hour (74 mph)

Hurricane Facts

  • Most Violent Storms on Earth!!!
  • Gets its energy from the heat of the
  • oceans surface.
  • Hurricanes that occur in the Pacific Ocean are called Typhoons.
  • Hurricanes occur Form between 5 degrees and 20 degrees latitude.

LINED PAPER…

What did just learn?

In sentence form, write what you just leaned about THE PARTS OF A HURRICANE.

Now, ask your neighbor to READ YOUR STATEMENT and then write a meaningful comment about PARTS OF A HURRICANE.

slide31

Hurricane Formation

In order for a hurricane to form, there must be a supply of warm, moist air for a long period of time.

slide32

Formationbegins in the tropic regions (5 to 20 degrees latitude).

  • Energy comes from condensing water vapor due to unstable humid air rising.
  • When water vapor condenses to liquid water it releases 540 kcal per mole.
  • When liquid water freezes to ice, it only lets off 80 kcal per mole.
slide33

For a hurricane to form it must begin to rotate (Coriolis Force).

  • -Hurricanes rotatecounterclockwisein Northern Hemisphere.
  • -Hurricanes rotate clockwise in Southern Hemisphere.
