For this assignment, you will analyze weather maps and interpret weather data sets. You will then use this information to answer a series of questions. Background Information
Many maps use a feature called isolines, lines that connect points that have equal value. For example, contour maps use isolines to connect areas with the same elevation. In meteorology, the study of weather, isolines are used to represent air pressure and wind speed. This assignment includes isohyets, which are isolines used to connect areas with similar amounts of rainfall.
There are several simple rules for maps with isolines:
1) Isolines connect points that have the same value.
2) Isolines cannot cross or touch.
3) The numerical distance between lines is called the interval, and on each map, the interval is the same between all lines.
4) An isoline represents the difference between higher and lower values.
5) Isolines show the amount of change over the distance between them. If the isolines are far apart, the change is gradual. If the lines are close together, the change is more prominent.
