Humidity
The scatter plots City Latitude vs. Humidity (2020-12-23) by total earth and then for each hemisphere separately seemed somewhat to describe a similar effect as for temperature. (This was relatively in line with our measurements approximately a month ago.) The closer the latitude to the equator the higher the mean and median humidity measurement. Or at least one could say the fewer outliers with low humidity. However, the Northern Hemisphere deviated from this inferential rule of thumb. Above about 40 degrees North, humidity measurements concentrated at increasingly higher measurements (approaching 100 percent, the maximum). One other aspect should be mentioned. At least visually, the humidity-latitude scatter concentrations did not track or concentrate as strongly as they did the temperature-latitude plots. Separately, we note that none of the weather readings we gathered reported any measurements above 100%, which would have called into question their vercacity.
