Latitude and Humidity
Humidity is the concentration of moisture in the air. Unlike temperature which has a recognisable pattern, the data for humidity suggests that there is no direct linear relationship between humidity and latitude. However, cities in the tropics (between -23.5° and 23.5°) tended to have less variation in humidity than cities in the temperate regions (north: 23.5–66.5° and south: -23.5– -66.5°). At the polar north, the cities tended to have humidiy readings close to 100%.
