Name: ______________________________________ Date: ________________________ Student Exploration: Weather Maps Vocabulary: air mass, air pressure, cold front, high-pressure system, knot, low-pressure system, precipitation, warm front Prior Knowledge Questions (Do these BEFORE using the Gizmo .) 1. How would you describe your weather today? ____________________________________ _________________________________________________________________________ 2. What information is important to include when you are describing the weather? __________ _________________________________________________________________________ Gizmo Warm-up Data on weather conditions is gathered from weather stations all over the world. This information is combined with satellite and radar images to create weather maps that show current conditions. With the Weather Maps Gizmo™, you will use this information to interpret a var iety of common weather patterns. A weather station symbol, shown at right, summarizes the weather conditions at a location. 1. The amount of cloud cover is shown by filling in the circle. A black circle indicates completely overcast conditions, while a white circle indicates a clear sky. What percentage of cloud cover is indicated on the symbol above? ____________________ 2. Look at the “tail” that is sticking out from the circle. The tail points to where the wind is coming from. If the tail points north, a north wind is moving from north to south. What direction is the wind coming from on the symbol above? ________________________ 3. The “feathers” that stick out from the tail indicate the wind speed in knots . (1 knot = 1.852 kilometers per hour.) A short feather represents 5 knots (9.26 km/h), a long feather represents 10 knots (18.52 km/h), and a triangular feather stands for 50 knots (92.60 km/h). Add the feathers to find the wind speed.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
