Only 3 stations had more days with high temperatures below zero than any other category. No stations had a peak of days with high temperatures in the 0°s or 10°s. Only 1 station (in the entire country!) had more days with high temperatures in the 20°s than any other category. That station was Keystone Ridge, Alaska. Figure 1 shows a sample of high temperature distributions for six stations across Alaska. Figures 2 and 3 are maps that show the spatial distribution of the peak categories.
I calculated the same information and made similar tables and maps for low temperature categories. Those will be the subject of another post.
Figure 1. Table of high temperature distributions for several stations is Alaska. Each station has a peak value in a different category.
Figure 2. Map showing the distribution of most frequent 10°F high temperature categories in Alaska. Note: No stations had peak values in the +0°s or to 10°s but the interpolation algorithm assumes those categories exist. Indeed, they must.
