The graph shows the July ratio of all-time record highs to lows for all USHCN stations with records going back to at least 1930. The three highest years were 1936, 1980 and 1934
The interesting thing about 1936 is that February of that year had a ratio of record lows to record highs of 35 to one. Weather can change very quickly…..
Easy to cool dry air …
Hey Harold, could you expound a bit more on the point you are making? Yes, dry air cools more easily, but I am not quite sure how that relates to a comparison of current and former heat waves. Are you implying that current air is dryer? Or wetter? Some more detail would be appreciated!
I don’t know how anyone survived the 1930’s without the media telling them 24 hours a day to “drink lots of water” and go into the shade when it’s hot.
I should have said that dry air warms and cools easily and that the yo-yo temperatures of 1936 that Steve alludes to reflect this.
