  1. Correlations Between Wind Direction and Precipitation Michelle Hsia Apr. 21, 2009 EAS4803

  2. Objective • To analyze data concerning wind direction and precipitation taken from a weather station. • To use different forms of regression to determine correlation between wind direction and precipitation.

  3. Data Source • Information comes from the National Climate Data Center (NCDC), and is collected by a Automated Service Observing System located at the Atlanta Hartsfield International Airport

  4. Data Source Cont. • A year’s worth of data with a daily sampling rate is used for this study. • Variables taken into account are wind direction (in tens of degrees) and total precipitation (in inches).

  5. Data

  6. Data Wind Direction & Cumulative Precipitation

  7. Regression

  8. Conclusions • It is shown by regression that there is a correlation between wind direction and total precipitation. • Cumulative precipitation increases with greater occurrence of a wind direction. • Pearson Correlation Coefficient is 0.0053
