On the Relative Humidity of the Atmosphere

open access: yes, 2021
Water vapour is highly subsaturated in much of the Earth's atmosphere. This has important consequences for water vapour feedback, and also for general phenomena such as the runaway greenhouse. In this chapter, we discuss the processes that create subsaturation, with reference to both observations, general circulation models, and a range of idealized ...
