The BBC article Soggy Ben Nevis can be remarkably dry describes results of a crowdscience effort to transcribe historical meteorological records recorded manually by researchers living on top of "Ben Nevis - the highest mountain in Britain."
The revelation that this notoriously wet peak should have times of near-zero humidity comes from the analysis of a newly recovered, unique data-set.
Weather observations were made around the clock by a group of men who lived atop Ben Nevis from 1883 to 1904.
Their records have now been digitised for modern science by volunteers.
Question: Just how dry could Ben Nevis get? Is this surprising?
Are there highly unusual conditions that must occur for the humidity atop Ben Nevis to drop as low as they are reporting, or in hindsight is this unsurprising?
