​Fronts - forms when 2 air masses meet

• ​Warm front - warm over cold, gentle rain, followed by warm weather

• ​Cold front- cold under warm, thunderstorms, followed by cooler weather

• ​Stationary front - cold meets warm, cloudy wet weather, rain lingers

• ​Occluded front - warm caught between 2 cold, cool temperatures with heavy rain or snow, followed by nice weather

​

Multiple Choice

Which will be the effect of a warm front moving into an area?

• light precipitation will begin as the front arrives and remain after the front is gone

• light precipitation will begin as the front arrives and clear after the front is gone

• Skies will clear as clouds are moved by the front and grow cloudy after the front is gone

• Skies will clear as clouds are moved by the front and remain clear after the clouds are gone

Multiple Choice

A cold front is expected to affect the local area overnight. Which weather condition will most likely occur?

• cloudy skies, precipitation and increased temperatures

• clear skies no precipitation and increased temperatures

• cloudy skies, precipitation and decreased temperatures

• clear skies no precipitation and decreased temperatures

Multiple Choice

The local weather station is predicting that a warm front will pass through Charlotte, NC in two days. How will Charlotte's weather most likely be affected by the passing of the warm front?

• The wind speed will increase

• The air pressure will increase

• The temperature will increase

​Weather vs Climate

• ​Weather - day to day condition of the atmosphere at a particular time and place

• ​Climate - average weather over a long period of time

Multiple Choice

A student states the weather is the same as climate. Which response best tells the student the difference between weather and climate?

• Weather is about the wind and the rain, but climate is about the clouds.

• Weather is the conditions in one day but climate is the conditions over a long time.

• Weather is measured with tools like thermometers, but climate is measured with tools like forecast.

• Weather is recorded on charts, but climate is recorded on world maps

Multiple Choice

Which observation describes a change in climate rather than a change in weather?

• The thunderstorm dropped about 3 cm of rain today.

• The average summer temperatures have increased over the last ten years.

• The snowfall in this area was more this week than last week.

• The average wind speed in April was less than it was in March.

Multiple Choice

Which information would be most helpful in determining the climate of a particular area?

• a news report of yesterday's weather

• today's data from a school weather station

• temperature records from the previous month

• local weather station weather records from the last ten years

​Air Pressure

• ​Low Pressure - rising warm air, cloudy skies and rainy weather

​

• ​High Pressure - sinking cool air, sunny clear skies ( fair weather)

​

Multiple Choice

Which correctly compares low and high pressure systems?

• A low pressure system usually brings cool dry air and clear skies, while a high pressure system brings clouds and precipitation.

• A low pressure system usually brings clouds and precipitation, while a high pressure system brings cool dry air and clear skies

• A low pressure system usually brings warm dry air and clear skies, while a high pressure system usually brings warm moist air and precipitation.

Multiple Choice

The forecast said a high pressure system will arrive this weekend. Benito and his friends want to go camping. Should they plan to go?

• No, the high pressure system will create storm clouds and tornados.

• Yes, the high pressure system will create skies filled with cumulus clouds.

• No, the high pressure system will increase humidity and cause rain clouds to form.

• Yes, the high pressure system will create clear sunny skies.

Multiple Choice

Which city is most likely to experience precipitation?

• W

• Z

• Y

​Weather Condition and Tools

• ​Barometer - measures air pressure

• ​Anemometer - measures wind speed

• ​Hygrometer- measures humidity

• ​Wind Vane - measures direction of wind

• ​Thermometer - measures temperature

​

• ​Air pressure - weight of air

• ​wind speed - how fast or slow wind blows

• ​humidity - amount of moisture

• ​wind direction - named for direction wind comes from
