is there a correlation between wind speed and ozone concentration in nc? erin cooper
TRANSCRIPT
Purpose•Surface ozone is harmful at extreme levels•0.075 ppm ozone = 100 AQI•Ozone and weather both change
constantly and affect us
Air Quality Index
Air quality Conditions Colors
0 to 50 Good Green
51 to 100 Moderate Yellow
101 to 150 Partially unhealthy Orange
151 to 200 Unhealthy Red
201 to 300 Very unhealthy Purple
301 to 500 Hazardous Maroon
Polluted ozone can irritate and/or damage
lungs, reduce lung function, or aggravate
asthma or other chronic lung diseases
Hypothesis
• A region’s wind speed and ozone concentration will have a climatology correlation, but a very little correlation.
• If my hypothesis is correct, I can expect a negative correlation between wind speed and ozone concentration
Procedure
1. Chose DAQ stations near weather stations2. Pull DAQ data from selected stations3. Pull daily average wind speed data from
weather stations4. Organize data sets to correlate easier5. Make correlation and graph data

The Southern Piedmont area had the most
correlation, supporting my hypothesis
The Northern Coastal Plain region had a
positive correlation, disproving my hypothesis
The Piedmont in general had the most correlation
I also noticed that regions with major
manufacturing cities had the highest
correlation
Conclusion•The piedmont region supported my hypothesis the
most, having the most negative correlation
•Most regions had VERY little correlation
•The Northern Coastal Plain region completely rejected my hypothesis by having a positive correlation
