The air temperature at 6 AM at the Ames Airport was 67°F and rose to 87°F at 3 PM, making for a 20 degree warm up during this period. Quantifying the magnitude of that daily warming is the subject of today's featured graph. The graph presents the weekly frequency of a given temperature change during that hour of the day time period. Of course, the vast majority of the time sees some warming during that period, but that is not always the case and certainly more common during the cold season months when solar inputs are less dominant. A simple climatology is plotted along with the 2024 values. Please note that both values are smoothed to remove some day to day noise. It is interesting to see the last number of weeks be around or just below average. This is likely due to a combination of the wet summer, which causes more input solar input to be used to evaporate water vs heating land, and also perhaps some due to the presence of overhead smoke reducing solar energy recieved.
