What type of past weather do the students see?
• Have the student place a red “L” on the map in the same location as they placed it on their surface pressure map. • Given the following information, have the students draw a cold front, in blue, and a warm front, in red, on the map. Remind the students of the Norwegian cyclone model to help determine which side of the low pressure area to place the fronts. The boundary between two air masses is called a front. As a result, fast moving cold fronts indicate a rapid change in the weather. Warm fronts also can have large changes in weather but the change is usually not as rapid as with a cold front. On a weather map fronts are drawn where there is large changes in temperature, changes in wind direction and speed, and between areas where there are large changes in pressure. On a weather map, fair weather is generally associated with “Highs” while stormy weather is associated with “Lows” and with the portions of fronts that extend from them. The location of the fronts should be similar to
