HTML clipboardAll this week on Weather Break, Dr. Jon Schrage is taking a look at some of the Earth’s weather extremes–the hottest places, the coldest places, the wettest places, and the driest places.  In today’s episode, he wraps up Extreme Weather Week by talking about the most humid places on Earth.  In terms of relative humidity, the most humid places on Earth are in the Arctic, where low temperatures and open water mean that the relative humidity is near 100% most of the time.  In terms of an absolute measure of water vapor content, such as the dewpoint temperature, the humid locations are around the Persian Gulf–places like Saudi Arabia and Iraq.  How can it be that some of the driest places on Earth are also the most humid? Tune in to find out.
