What 4 variables describe weather?
What is 1. wind speed and direction 2. pressure 3. temperature 4. amt. of moisture in the air.
100
An expression of how saturated the air is for a given temperature is called...
What is Relative Humidity
100
A violently rotating column of air in contact with the ground.
What is a tornado.
100
An air mass that forms over a land is close to the equator is called...
What is Continental Tropical
100
4 important variables to look for when reading a weather map include....
What is 1. Temperature shifts 2. Fronts 3. Pressure 4. Air masses
200
When cloud droplets fall and pass through warm air followed by cold air near the ground the form of precipitation that falls is called...
What is sleet
200
The temperature at which water vapor will condense is called...
What is Dew Point
200
Rapid movement of air causes different parts of a cloud to become oppositely charged and a current flows between regions of opposite electric charge.
What is lightning
200
This forms when a warm air mass gets caught between two cooler air masses, pushed up, and "cut off" from the ground.
What is an occluded front
200
Fronts and bad weather are associated with _________ pressure areas.
What is low
300
This type of precipitation is formed when water freezes and partially melts repeatedly by being tossed up and down inside a cloud.
What is hail
300
When the temperature and dew point are equal the relative humidity is ________ %
What is 100%
300
A hurricane gets its energy by sucking this up.
What is warm moist air *Bonus*(50pts) What is dispensed higher up as a result?
300
This forms when a moist, warm air mass slides up and over a cold air mass. It brings gentle rain or light snow followed by warmer, milder weather.
What is a warm front.
300
Draw the symbol for a cold front in Cleveland that is moving SE.
What is (See drawing)
400
Encode the following station model 1. Temperature 3 C 2. Dew Point: 2 C 3. Wind: NE at 25 knots 4. Pressure: 987.6 5. Current Weather: light snow
What is (check station model picture)
400
1. Temperature is 32 F, Dewpoint is 32 F, Relative Humidity=100% 2. Temperature is 86 F, Dewpoint is 68 F, and Relative Humidity = 50% In which example is there a greater amount of moisture?
What is example 2 because the Dewpoint temperature is higher which means the air is holding a lot more moisture. Warm air can hold more water vapor.
400
Weather conditions are considered to be a blizzard when... (must get 3 out 4)
What is 1. Temperature is low 2. Winds are 56 km/hr 3. Visibility is less than 400 meters 4. Conditions persist for 3 hours or longer.
400
When moist warm air gets pushed up the side of a mountain, water vapor cools and condenses.
What is Relief Cloud Formation
400
High pressure areas have winds that travel __________ in the Northern Hemisphere and ____________ in the Southern hemisphere. *Bonus* (50 pts.) What causes this?
What is clockwise, counterclockwise Bonus: Coriolis Effect
500
Contrast High and Low pressure areas (2 facts each).
What is High Pressure: 1. sinking motion makes it difficult for air to rise, cool, and condense 2. winds blow away from the center of high pressure areas Low Pressure 1.warm air rises and condenses forming clouds. 2.associated with high winds and warm air that blow towards the center of low pressure.
500
Relative humidity indicates how close the dew point is to its' current temperature. Does a low relative humidity indicate that the dew point is closer or further apart than the current temperature?
What is further apart. RH refers to how saturated the air is. Dew point refers to the temperature at which water will condense. Then, the closer the temperature is to the dew point the more saturated the air is.
500
Hurricanes are also called ___________ and ___________. Where does each one form?
What is typhoons in the Pacific Ocean and Cyclones in the Indian Ocean.
500
Rays from the sun heat the ground and the air next to it. The warm air rises and cools, causing condensation to form on particles in the air.
What is Convectional Cloud Formation
500
A cold front has just passed through Chicago. What kind of weather can Cleveland expect? How do you know?
What is Cleveland can expect bad weather since weather and fronts move from west to east across the US.
