What a difference a few months makes. Back in January I was visiting Utqiagvik as a guest of Argonne’s Education and Outreach team. When we arrived it was -20F and lets just assume the dewpoint was -20F. Today I went for a run in Nanjing, China with a (5am) temperature of 70F and a dewpoint of 65F. In China each kg (roughly a cubic meter has 13.37 grams of water in the form of vapor. In Utqiagvik it was a mere 0.35g. From the dry to the dripping wet!
