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.
