Unit 5 Topic 3 and 4

Weather and Climate and Climate Regions

Weather

• Weather is the day to day conditions outside in your area.

• Snow, rain, hail, sunshine

Climate

• Climate is the long term temperature and precipitation in an area.

• Climate is over along period of time, this can be months or years, and seasonal (winter, summer spring and fall conditions)

Multiple Choice

Is the following an example of climate or weather: Yesterday it was sunny, but today we have storms

• weather

• climate

Multiple Choice

• weather

• climate

Multiple Choice

Is the following an example of climate or weather: Florida is a popular vacation spot because of consistent sunny days and warm temperatures.

• weather

• climate

Latitude

Latitude is horizontal..

Lines are flat.

Includes the equator (0 degrees longitude)

Equator gets the most sun!

It is either North or South of the Equator.

Longitude

Longitude is vertical

Like the y-axis!

Multiple Choice

The equator is ...

• latitude

• longitude

Multiple Choice

Which of the following areas of Earth receives the most solar energy?

• Prime Meridian

• South Pole

• North Pole

• Equator

Climate Zones

There are three climate zones

Temperature Ranges

• Temperature ranges vary by region

• Florida is considered Tropical AND Temperature (Panhandle)

The Earth is Curved!

• This curve of the Earth causes same amount of solar energy to spread over larger areas

• The energy source of winds is the Sun!

Multiple Select

What point receives the least amount of solar energy?

• equator

• North pole

• South Pole

• Florida

Multiple Choice

Where can you access a daily forecast?

• Almanac

• Encyclopedia

• Newspaper

• Science Textbook

Freezing and Boiling Water!

Water freezes at 0 degrees C (or 32 degrees Fahrenheit)

Water boils at 100 degrees C (or 212 degrees Fahrenheit)

Multiple Choice

Which of the following temperatures would you see snow at?

• 12 degrees Celsius

• 32 degrees Celsius

• 0 degrees Celsius

• 100 degrees Celsius

Jet Stream

• Narrow band of high wind found in the upper atmosphere

• Look closely at the picture on the next slide. What can you you infer about weather from the picture?

Open Ended

What did you infer from the picture?

Wind and Precipitation

Wind influences precipitation because it carries water vapor to other places.

Multiple Choice

What is the energy source of the wind?

• Sun

• Moon

• Stars

• Water

What Affects Air Pressure

• Air pressure is the weight of air molecules pressing down on the Earth.

• Affected by altitude (sea level)

• Causes winds to occur due to diffusion (air molecules move from high to low concentrations)

Multiple Choice

If you were standing on a mountain would you be experiencing

• High air pressure

• Low air pressure

• No air pressure

Fronts

• a boundary between air masses of different temperatures

• The 2 air masses have different density

• Cold air = more dense (heavy) then hot air

• Hot air = more pressure then cold air

Cold Fronts

• Move quickly

• bring cooler weather

• Push warm air masses up

Warm Fronts

• Bring Warmer Weather

• Brings drizzly rain followed by clear weather

• The warm air rises over the cold air

Stationary Front

• does not have enough force (wind) to move

• brings many days of unchanging weather

• 
  

Multiple Choice

Which type of front brings cooler weather?

• Cold front

• warm front

• stationary front

• occluded front

Sea Breeze

• Land is hotter than water

• Cold air moves into land while hot air moves out over water

• Comes from the sea and blows towards the land

• This is convection

Land Breeze

• Water is warmer then the land (Night)

• Warm air moves into land and cold air blows out over the water

• Comes from the land you blows toward the sea.

• This is also convection.

Gulf Stream vs Jet Stream

• Gulf stream is an ocean current

• Jet Streams are high winds up in the atmosphere
