Essential Question:

How do I explain the movement of air masses and their effect on weather?

Comparing Weather and Climate

Weather Climate

Both weather and climate deal with the condition of the atmosphere.

Day to day (shorter time)

Years(longer time)

1. What is the major difference between weather and climate? A. air temperature B. air pressure C. humidity D. time

2. Which of the following is an example of climate?

A. The current temperature in Pinehurst, NC B. The relative humidity in Atlanta C. The average current temperature in a region D. The average temperature in Winston

Salem,NC over the past 30 years

3.Decribe the 4 different types of air masses?

Maritime air mass

Tropical air mass

Polar air mass

Continental air mass

Cold air coming from the North, North East, NW

Humid air coming from the oceans

Warm air coming from the South, South East, SW

Dry air coming from Canada and Mexico

Warm or hot region because of its nearness to the equator.

Cold region because of its nearness to the North pole.

4. What are the common characteristics of the air masses in United States?

6. How are hurricanes and tornadoes related to air masses? A. They form where air masses

meet. B. They form where air pressure is

the same. C. They form where air temperatures

are the same D. They form within air masses.

Most violent weather. Thunderstorms and tornadoes.

Less violent weather (light to moderate precipitation)

changes from higher to lower temperatures

Characterized by storms that are dissipating or dispersing.

Causes flooding due to continuous rain.

7. What are the four types of fronts and the weather they bring?

8. Describe the direction of the following weather fronts?

Cold front-violent weather

Moves to the direction of the cold air mass

Cold air mass

Warm front - light or moderate rain.

Moves to the direction of the warm air mass

Warm air mass

Moves to the direction of the cold air mass

Occluded front-appears when storms disperse.

Stationary or does not move.

Stationary front- long days of rain ( flood).
