Weather Hazards Flashcards
Write a Definition Of Atmospheric Circulation?
- It Is The Layer Of Air Surrounding The Earth Surfaces.
Write a Definition Of Global Atmospheric Circulation?
- It Is The Way Our Atmosphere Circulates Around The Earth.
How Many Cells Are Circulating The Earth?
- 6
How Many Are Found In The North and South Hemisphere?
- 3
What Repeats On Both Sides?
- The Same Number Of Patterns and The Same Number of Cells.
Name The 3 Different Types Of Cells?
- Hadley
- Ferrel
- Polar
Describe The Location Of The Hardly Cell and What Is Created?
- Its Located At The Equator The Hot,Moist Air Rises and Creates Low Pressure.Then It Moves To a Higher Latitudes 30° and Cools and Condenses Forming Clouds.
What Happens When The Heated Air Has Risen?
It Divides and Goes To The Northern and Southern Hemisphere.
What Type Of Pressure Does Cool Are Create When Its Sinks and What Isn’t Created?
- High Pressure
- This Means Clods Can’t Form.
Describe The Location Of The Ferrel Cell and What Is Created?
- At 30°-60° latitude, warm air travels north and meets cold air blowing from the poles. The interaction causes the warm air to rise as it is forced upward by the cold air, creating a region of low pressure.”
Write a Definition Of Polar Front?
- The Polar Front Is a The Boundary Between Cold Air From Polar Regions and Warm Air From Areas With Lower Latitudes.
How Many Millimetre do Areas On The Polar Front and What’s The Average Temperature?
- 1,500 - 2,000mm Per Average.
- The Average Temperate Is 16°
Describe The Location Of The Polar Cell and What Is Created?
- They are Located 60° North Or South Of The Equator Moist,Warm Air Rises and Travel To The Pole (90°) Where Is Sinks.
Write a Definition Of a Pressure Belt?
- These Air Circulations That Create Different Areas Of Pressure.
Write The Difference Between High and Low Pressure?
- Low Pressure Is When Air Rises.
- High Pressure Is When The Air Sinks.
Describe The Location Of Where High Pressure Happens?
- It Happens at The Poles and 30° Either Side Of The Equator.
Describe The Location Of Where Low Pressure Happens?
- It Happens 60° Either Side Of The Equator
Explain Where The Hottest Place Is On Earth and Explain Why?
- The Equator Is The Hottest.
- This Is Because The Suns Heat Is More Concentrated.
Explain Where The Coldest Place Is On Earth and Explain Why?
- The North and South Pole.
- This Is Because The Suns Heat Is More Concentrated.
Describe The Definition Of Temperate and Tropical?
- Tropical Is Warm Weather.
- Temperate Is Mild Weather Not To Cold Or Hot.
What’s The Weakest Cell and Explain Why?
- Ferrel Cell
- Because It Has a Weak Heat Source and Heats Rises Creating High Pressure.
Surface Winds Will Blow From (_______) Pressure To (________) Pressure.
- High and Low
What’s The Area Near The Equator That Gets Low Pressure?
- Doldrums
Where Do Trade Winds Once They Have Gone To The Dessert?
- Doldrums
What 3 Other Names Do Tropical Storms Also Have?
- Typhoon
- Cyclone
- Hurricane
What Provides Energy For a Strom?
- Warm Ocean Water
Why Do Storms Slow Down When They Hit Land?
-Because They Lose Their Source Of Energy (The Sea)
Describe 4 Facts About Tropical Storms?
- They Happen Between 5° And 20° North and South Of The Equator When The Temperature Is 26° Or Over.
- Winds Are In Excess Of 160KM Per Year.
- Intense Rainfall Happens After It (250-300 mm).
- It Can Cause Landslides and Surges.
