Predicting the Weather: Main Ideas

1) Who needs to know what the weather will be? (pg. 278-279)

a) Meteorologist, people, farmers

Quick Check (pg. 279)

-Critical Thinking: What are symbols

you could use to show on a map what the weather is like? a) Cold Front: line with triangles, Clouds: pictures of clouds, Warm Front: a line with mounds on it, Snow: snow flakes, Temperature: use different colors for different temperatures (red=hot & blue=cold), High Pressure system: H, Low pressure system: L, Rain: little dots or dashes, Cyclones: spiral or swirl, Wind: curvy dotted line.

2) What do weather fronts tell you?

(pg. 280-281)a) They tell you what the weather is going to be like in

the future.

Quick Check (pg. 281)

-Compare and Contrast: How does what low

and high pressure systems tell you differ from

what warm and cold fronts tell you? a) Warm and Cold fronts tell you weather is approaching. Low pressure signals warmer air and high pressure signals colder air.

3) What do lows and highs tell you?

(pg. 282-283)a) They tell us about what our local weather is like.

Quick Check (pg. 282)

-Critical Thinking: What is the difference between high and low pressure air masses?

a) A low pressure system is a large air mass with a low pressure center. A high pressure system is a large air mass with a high pressure center

4) How do weather forecasters collect data? (pg. 284)

a) computers, satellites, radar, airplanes, weather balloons

Quick Check (pg. 284)-Critical Thinking: Why does having

additional data help meteorologists make forecasts more accurate? a) It is important to look at many key factors to make accurate predictions.
