Wind Direction

Everyone is affected by air pollution because the air we breathe does not stay in the same place. The air moved, and the wind carries pollution across hundreds of miles. The pollution created, no matter how small, grows when combined with other small amounts of pollution.

In meteorology, wind direction is measured from the direction it is blowing FROM. A wind rose is used to show the relative frequency of the wind direction at a location.

Looking at the data from the WeatherSTEM station at over the past week, answer the following questions:

  • Which directions has the wind been blowing from the most?
  • What were the maximum wind speeds?
  • Did you notice any changes in the air quality over the past few days? If so, can you identify the sources of air pollution?
