Forecasting
100
The definition of this term is "atmospheric conditions along with short-term changes of a certain place at a certain time"
What is "weather" ?
100
This type of pressure system typically brings cloudy skies, and possible rain.
What is a "low pressure system" ?
100
This is the boundary between two opposing air masses.
What is a "weather front" ?
100
Describes what happens to the air when a cold front approaches.
Warmer air pushes up vertically, very quickly. Condensing and forming powerful storm clouds along the front line.
100
Chicago has a pressure of 995 mb whereas Detroit has a pressure of 1050 mb.
Where would you expect there to be cloudy skies and possible precipitation?
Chicago
200
This weather variable is the average kinetic energy of an object.
What is "temperature" ?
200
Air molecules move ________ in low pressure systems and move ________ in high pressure systems.
What is "upward in low pressure systems, and downward in high pressure systems" ?
Air moves from areas of high pressure to areas of low pressure.
200
This type of air mass originates over water near the tropics.
What is a "maritime tropical" air mass?
200
Describes what happens to the air when a warm front approaches.
Warm air slowly glides over denser, cooler air. Clouds and precipitation form over large areas of land.
200
DAILY DOUBLE: Wager an amount of points you have accumulated before the question is given.
Warm front passed through the region starting on Tuesday - increase in temperature, cloud coverage, and rain for an extended amount of time
300
Air pressure is lower at higher altitudes because ...
There are less air molecules per unit volume (less dense air molecules) at higher altitudes.
300
A high pressure system brings this type of weather.
What is "clear skies, and pleasant weather" ?
300
This type of front is where two opposing air masses meet and neither has enough energy to overtake the other.
What is a "stationary front" ?
300
Air pressure is measured with this device.
What is a "barometer" ?
300
Make a weather prediction for southern Michigan.
Clouds and light precipitation for the next few days followed by warmed weather.
400
DAILY DOUBLE: Wager an amount of points you have accumulated before the question is given.
What is "75%" ?
400
This type of air mass originates over land in cold regions.
What is "polar continental" air mass?
400
Describe how air flows on the ground at high pressure systems versus at low pressure systems.
High pressure systems - air moves away from the high pressure center.
Low pressure systems - air moves towards the low pressure center.
400
This is an intense tropical storm with winds exceeding 119 miles per hour.
What is a "hurricane" ?
400
Make a forecast for cities in the middle of Texas.
Heavy local rainfall and thunderstorms for the next day followed by lower temperatures.
500
This type of precipitation starts as a small piece of ice that is repeatedly lifted and dropped by an updraft of air.
What is "hail" ?
500
The weather at cold fronts are like this, whereas the weather at warm fronts are like this.
At cold fronts - localized severe storms and heavy precipitation. Colder weather to follow.
At warm fronts - light rain and clouds over a large area. Warmer weather to follow.
500
Describe what's going on during an occluded front and what type of weather you could expect.
A cold front moves fast and catches up to a warm front. Warm air pushed up, clouds form, rain is likely.
500
Wind speed is measured with this type of device.
What is an "anemometer" ?
500
This is the type of weather you would expect in Colorado TODAY.
Today - clear because high pressure system.
