When it comes to humidity, one environment that often comes to mind is the landscape of tropical rainforests. The majority of these environments in the world are found between the tropic of cancer (located 23 degrees N of the equator) and the tropic of capricorn (located 23 degrees S of the equator).
From our plot of Latitude vs. Humidity, one can see that there is a large majority of data points within the latitudes of 45 degrees North and 45 degrees S, which for the most part justifies our above statement. However, there seems to be a different array of data points pertaining to the 60-80 degrees N range in which there are a considerable amount of high humidity recordings, but also a handful of cities that recorded a humidity percentage of 0%. It would be fascinating to pinpoint cities within the 60-80 degrees N on a map to visualize where they are.
