Unit 8 Whiteboard Review
  • Weather and Climate

2
Weather
  • What area of the Earth receives direct sunlight?
  • The equator
  • What area of the Earth receives indirect
    sunlight?
  • The poles (north and south)
  • The uneven heating of the Earths surface
    causes__________.
  • Convection currents

3
Weather
  • Due to convection, what does the warm air from
    the equator do?
  • Rises towards the poles
  • Why does the warm air rise?
  • The warm air is less dense
  • What does the cold denser air from the poles do?
  • Sinks towards the equator and fills the space.

4
Weather
  • What type of pressure system causes dry
    conditions and fair skies?
  • High Pressure
  • What pressure system causes stormy weather and
    clouds?
  • Low Pressure
  • What is air pressure?
  • The amount of pressure on a surface from the
    atmosphere above it.

5
Weather
  • What causes winds or breezes?
  • Uneven heating of the Earths surface
  • What type of air masses form over land?
  • Continental (polar, arctic, tropical and
    equatorial)
  • What type of air masses form over water?
  • Maritime (polar, arctic, tropical and equatorial)

6
Weather
  • What is the coldest air mass?
  • Continental and maritime arctic
  • What is the warmest air masses?
  • Continental and maritime equatorial
  • Which air masses affect Texas the most directly?
  • Continental Tropic and Maritime tropic

7
Weather
  • Which air mass is dry and the coldest?
  • Continental Arctic
  • Which air mass is moist and the warm, but not as
    warm as the equator?
  • Maritime Tropical
  • Which air mass is dry and cold (but not the
    coldest)?
  • Continental Polar

8
Weather
  • Why do air masses travel from polar regions to
    the equator?
  • Their densitywarm air rises up towards the poles
    and cold air sinks down and fills those spaces.
  • What tool do we use to measure air pressure?
  • Barometer
  • What unit does a barometer measure in?
  • Millibars (mb)

9
Air Masses
  • Which air mass is 1?
  • Continental Arctic
  • Which air mass is 2?
  • Maritime Polar
  • Which air mass is 3?
  • Continental Polar
  • Which air mass is 4?
  • Maritime Tropical

Weather
  • What types of air masses are DRY?
  • Continental
  • What types of air masses are MOIST?
  • Maritime
  • What is the boundary between two air
  • masses called that brings changes in
  • weather?
  • Fronts

11
Weather- Fronts
  • What type of front brings warm and humid weather?
  • Warm Front
  • Draw the symbol for a warm front.
  • What type of front brings rain and storms and
    leaves the area with cooler temperatures?
  • Cold Front
  • Draw the symbol for a cold front.

12
Weather- Fronts
  • What type of front causes cloudy weather with
    chance of precipitation?
  • Stationary Front
  • Draw the symbol for a stationary front.
  • What type of front leads to many days of clouds
    and precipitation?
  • Occluded Front
  • Draw the symbol for a occluded front.

13
  • What type of front is by Miami?
  • Stationary Front
  • What type of weather will Miami have now?
  • What type of air pressure is by Kansas?
  • High Pressure
  • What type of weather around Kansas?
  • Clear skies, and mild weather

14
Winds
  • Does wind always move in the same direction?
  • No
  • Name two things that affect wind direction and
    cause different wind belts.
  • Convection currents and Coriolis Effect
  • What type of ocean current is created and caused
    by wind?
  • Surface currents

15
Winds
  • Draw the wind direction in each wind belt.
  • Start with the Easterlies and work down towards
    the trade winds at the equator.

16
Answer
17
Winds
  • How does the Coriolis Effect change wind
    directions?
  • It causes the curved paths of winds patterns in
    the different wind belts
  • What is a jet stream?
  • Narrow air currents found in the atmosphere of
    the Earth.

18
Ocean Currents
  • What type of currents are caused by convection,
    and make up 90 of currents?
  • Deep water currents
  • What has a higher specific heat, water or land?
  • Water
  • What is the name of the surface current that
    travels along the eastern part of the US and
    brings stable, temperate weather to Europe?
  • Gulf Stream

19
El Nino
  • Does El Niño occur every year?
  • No, every 2 to 7 years
  • During El Nino, what can happen to the trade
    winds?
  • Stop blowing, change direction or blow less
  • What does El Niño do to the ocean temperature in
    the Pacific Ocean?
  • Causes it to get warmer, increases the temp.

20
Hurricanes
  • What conditions cause hurricanes to form?
  • Low pressure and warm ocean water
  • What would happen if hurricanes travelled over
    cold ocean water?
  • They would weaken
  • What types of damage do hurricanes cause on land?
  • Storm surges, flooding, tornadoes, and strong
    winds

21
Hurricanes
  • What is the weather like in the eye of the
    storm?
  • Calm no strong winds or precipitation
  • What area of the globe are hurricanes most likely
    to form in?
  • The tropics, close to the equator
