# Weather Observations For December 18, 1990

The following data was taken at various locations around the Puget Sound area. Plot the temperature, wind speed, and wind direction for a particular time on one map. All stations for that time should be on the same map. You will have three maps when finished: one for 4:00 am, one for 1:00 pm, and one for 10:00 pm.

Wind speeds are in knots and temperatures are in degrees Fahrenheit.

Note: 1 "knot" means 1 nautical mile per hour and is about 1.15 miles per hour. A nautical mile is one-sixtieth (1/60) of a degree of latitude on a great circle. A nautical mile is used in aviation and marine navigation. A nautical mile is about 6076 feet.
