Ames v. Ankeny

Posted: 21 Mar 2017 05:33 AM

The afternoon high for Ames and Ankeny based on their respective airport sensors was 66 degrees on Monday. While only separated by 20 some miles, the typical afternoon high temperature difference between the two sites is about 3-4 degrees with Ankeny (the southern most station) being warmer. The featured chart compares the difference in afternoon high between the sites by day of the year and also average wind speed. The data is presented as a heat map with a simple average computed over the individual bins. It is kind of interesting to see a small annual signal in the plot with the immediate explanation being micro-climate differences between the sites likely due to subtle terrain and soil differences.
