|
What causes the Coriolis Effect?
|
The rotation of the Earth
|
|
|
What is air pressure?
|
Force that excerts over a certain area due to it's weight or motion.
|
|
|
What are the three types of heat exchange?
|
1. conduction
2. convection 3. radiation |
|
|
What is conduction?
|
The transfer of heat within or from a substance to another as a result of molecular motion. ALWAYS FROM WARM TO COLD!
|
|
|
What is convection?
|
Convection - transfer of energy and mass by motions in a liquid or gas. In the atmosphere, convection usually refers to the vertical interchange of air masses. An example of convection is the rising of warm surface air and the sinking of cold air from upper levels of the atmosphere.
|
|
|
What is temperature?
|
Temperature - A degree of hotness or coldness the can be measured using a thermometer.
|
|
|
How is temperature measured?
|
Temperature is measured in degrees on the Fahrenheit, Celsius, and Kelvin scales.
|
|
|
What is volume?
|
Volume - The amount of space occupied by a substance or object.
|
|
|
What is a liter?
|
Liter - Basic unit of volume in the metric system.
|
|
|
What is kinetic energy?
|
Kinetic energy - The energy of motion; the energy an object has as a result of its motion.
|
|
|
What is a funnel cloud?
|
Funnel cloud - A rotating column of air extending from a cloud but not reaching the ground.
|
|
|
What is force?
|
Force - Push or pull that gives energy to an object, sometimes causing a change in the motion of the object.
|
|
|
Does warm air have low of high density when compared to cold air?
|
Warm air has high density when compared to cold air.
|
|
|
Does cold air have low or high density when compared to warm air?
|
Cold air has high density when compared to warm air.
|
|
|
What is condensation?
|
Condensation - The process by which a gas or vapor changes to a liquid.
|
|
|
What is a cloud?
|
Cloud - A visible collection of very fine water droplets or ice crystals suspended in the atmosphere at altitudes from just above the ground to several miles above sea level.
|
|
|
How wide can hurricanes be?
|
Hurricanes can be up to 600 miles across.
|
|
|
Describe 3 characteristics of the winds of a hurricane?
|
Hurricane winds:
1. SPIRAL counter-clockwise in the northern hemispher; 2. inward and upward; 3. from 75 mph to 200 mph. |
|
|
Which part of the hurricane is the calmest part? What is it called?
|
The eye of a hurricane is the calmest part with light rain and light winds.
|
|
|
Which direction does the low level winds blow on a hurricane in the Northern Hemisphere?
|
Counter-clockwise
|
|
|
Which direction does the low level winds blow on a hurricane in the Southern Hemisphere?
|
Clockwise
|
|
|
Why do lower level winds of a hurricane blow counter-clockwise in the Northern Hemisphere?
|
The Coriolus Effect in the Northern Hemisphere force the winds of a hurricanes to the right or counter-clockwise.
|
|
|
Why do lower level winds of a hurricane blow counter-clockwise in the Southern Hemisphere?
|
The Coriolus Effect in the Southern Hemisphere force the hurricanes to the left or clockwise.
|
|
|
Do hurricanes need cold or warm water to form? Why?
|
Hurricanes need warm ocean water, above 80 degrees F, to provide energy and causes more evaporation making the air and clouds humid.
|
|
|
What wind speed does a Hurricane have?
|
Hurricanes have wind speeds speed greater than 64 knots (74 mi/hr).
|
|
|
Why are hurricanes important?
|
Hurricanes are important because they push warm air from the tropics to the cooler temperature areas.
|
|
|
At what lattitudes do hurricanes typically form?
|
Hurricanes typically form between 5 and 15 degrees lattitude north or south of the equator
|
|
|
Name for major oceans that hurricanes usually form?
|
Hurricanes thunder across the warm oceans of the world such as the Atlantic, the Gulf of Mexico, the Caribbean, and the Western Pacific Ocean (where they are called typhoons), up to higher latitudes.
|
|
|
What are hurricanes called in the Western Pacific Ocean?
|
Hurricanes in the Western Pacific Ocean are called typhoons.
|
|
|
What months and seasons do Hurricanes usually form? Why?
|
Hurricanes happen when the oceans have been warmed during summer months. In the North Atlantic, hurricane season is from June 1 to November 30, but most hurricanes happen during the fall.
|
|
|
True of false?
A hurricane with winds of 125 miles per hour means that the hurricane moves across the ocean or land at 125 mph. Why or why not? |
No, hurricanes with winds from 75 to 200 mph only travels about 15 mph.
|
|
|
Coriolis effect
|
the circulation of winds that travel in different directions
|
|
|
Tornado
|
a violently rotating column of air that is in contact with both the surface of the earth and a cumulous cloud
|
|
|
land breeze
|
at night he land cools off faster than the ocean due to differences in the heat capacity which forces the dying of the daytime sea breeze
|
|
|
hurricane
|
a tropical cyclone occurring in the North Atlantic Ocean or the North Pacific Ocean, east of the international date line
|
|
|
humidity
|
the amount of water vapor in the air
|
|
|
wind
|
the movement of air
|
|
|
low pressure
|
region where the atmospheric pressure is lower than that of surrounding locations
|
|
|
high pressure
|
when the atmospheric pressure at the surface of the planet is greater than the surrounding environment
|
|
|
water cycle
|
describes the continuous movement of water on, above and below the surface of the earth
|
|
|
thunderstorm
|
a form of turbulent weather characterized by the presence of lightning and its acoustic effect
|
|
|
weather
|
the condition of the atmosphere at certain time and place
