Part C
When air cools below its dew point temperature, the drops of water in the air condense, forming dew. Dew point temperature varies according to air pressure and humidity. When the air temperature is close to its dew point, there's more moisture in the air, and the chances of rain and thunderstorms increase. On a map, isodrosotherms connect points of equal dew point temperature and indicate surface moisture.
Question
This map shows the dew point temperatures across the United States. The units are measured in degrees Fahrenheit. Follow the steps to complete the drawing.
Step 1: Isodrosotherms. Locate points of equal dew point temperature on the map. Use a green pen to connect these points by drawing smooth isodrosotherms. Make sure the isodrosotherms don't cross each other. You may have to estimate some of the values. Label the isodrosotherms at the end of the line.
Step 2: Storms. Isodrosotherms indicate surface moisture. Typically, dew points greater than 70°F have the energy needed to produce severe weather. Shade the regions where dew point temperatures are 70°F or greater in green.
