Sorry this is late. See you tomorrow.

2. There are 4 air masses that affect North America. List them, say where they begin and their characteristics.
continental polar: Dry/cold Northern areas over land
2. There are 4 air masses that affect North America. List them, say where they begin and their characteristics.
continental polar: Dry/cold Northern areas over land
maritime polar: wet/cold. Gulf of Alaska
continental tropical: dry/warm. Texas
maritime tropical: wet/warm Gulf of mexico
3. How are winds named?
For where they originate. (northerly comes from the North)
4. What is albedo?
-Amount of reflection of light back into the atmosphere. Dark colours will absorb more radiation than white
5. What are the different ways that we (know??) a temperature inversion happening?
-On cool, clear nights as we lose radiation the air near the ground will be colder than the air above it.

-On cool, clear nights as we lose radiation the air near the ground will be colder than the air above it.
-Cool air flows down mountainsides into valley and pushes the warmer air out of the way. This leaves cold dense air at the valley bottom and warmer air above.
6. Explain the difference between Relative and Absolute Humidity
Relative humidity is the percentage of water vapour in the air
6. Explain the difference between Relative and Absolute Humidity
Relative humidity is the percentage of water vapour in the air
Absolute humidity is the amount of water vapour in the air
7. Compare & contrast hurricanes and tornadoes in terms of the following: where they occur? how they form? wind speed? potential impacts? when they occur?
7. Compare & contrast hurricanes and tornadoes in terms of the following: where they occur? how they form? wind speed? potential impacts? when they occur?
Hurricanes: Where: Areas with warm water How: Warm water evaporates from the ocean and forms into a large storm. Wind Speed: up to 300 miles per hour potential impacts: Rain, storm surge, wind, etc When: In Atlantic in the late summer months.
Tornadoes: Where: Tornado Alley How: convectional storms. Warm moist air meets cold dense air. Wind Speed: up to 500 miles per hour Potential impacts: Mainly strong winds, hail. When: Late winter to spring.
8. What is a storm surge?
Wall of water being pushed up onto the coast from a hurricane.

9. Draw & explain the 3 types of precipitation. Go through the steps of WARCCAP. Where does each one occur?
Orographic: Warm air is pushed up onto a mountain. As the air moves up and over the mountain it begins to cool and condense. Once it reaches the dew point we begin to see precipitation on the windward side of the slope. occurs in mountainous regions.
Convectional: As the ground is warmed by the sun the warm air rises. As it rises into the atmosphere is begins to cool, condense and precipitates. Usually forms storms. Common in tropical regions and in the middle of continents.
Frontal: Warm air mass is slowly pushed up as it meets a cold air mass. As it rises it cools, condenses and begins to precipitate. Common in Vancouver

10. What is a Chinook? How does it occur? Where are they common in Canada?
A chinook is a warm wind that occurs on the leeward side of mountain ranges. Occurs as the dry air moves down the mountain. As is flows down the mountain it warms the air. Common in Alberta.
11. List the different instruments found within a weather station and tell what they measure.

barometer: Pressure
wind vane: wind direction
thermometer: temperature
hygrometer: humidity
anemometer: wind speed
rain gauge: precipitation
12. temperature: -7
dew point: 0
pressure: 104.85kpa
Pressure rising or falling: +9
wind direction: southerly
cloud cover: 1/4
13) 98.89kpa
95.52kpa
101.01kpa
14) calm winds, sunny skies. cloudless
15) Temperate desert drops below zero in the winter months. Colder than a tropical desert. Both receive very little precipitation
16) Equatorial. Temperatures always above 20 degrees celsius. High amounts of precipitation all year around.
17) Mediterranean
18) Ozone Depletion: CFC's in the atmosphere/ Higher rates of skin cancer
Acid Rain: Nitrous Oxide from industry/ Acidic soils
Climate change: Increased amounts of Carbon Dioxide in the atmosphere/ melting glaciers
19) Top left: Tropical wet/dry (WHY? temperatures above 20 degrees all year tells is it is tropical. Wet and dry season but less rain than Monsoon)
Top Right: West Coast marine
Bottom: Temperate Steppe (between 200-400 mm of rain so steppe. Temperature drops below zero so not tropical.
