That psychrometer is 1. an instrument used for measuring relative humidity. the simplest sling psychrometers consist of two thermometers mounted on a rotating frame. one thermometer's bulb is kept moist, the other dry. by comparing the "wet bulb" and "dry bulb" readings of the two thermometers after they have been whirled in the air, one can determine the relative humidity. an electric fan is used to ventilate the wet bulb in many psychrometers [23]. 2. apparatus designed to measure relative humidity indirectly [16]. see also hygrometer.?

Origin of the limestone pedestals at Norber Brow, North Yorkshire, UK: a re-assessment and discussion
Abstract:

Contrasting rates of limestone dissolution to account for the development of limestone pedestals beneath erratic boulders at Norber, North Yorkshire, have been proposed. Most of these estimates were made prior to reliable dates being available for erratic emplacement and prior to detailed knowledge of the pattern of regional 'post-glacial' climate change. The erratics were deposited c. 18 ka BP, and for a substantial part of the ensuing c. 4 ka a climate of Arctic severity prevailed until the abrupt warming at 14.7 ka BP, marking the onset of the Lateglacial Interstadial. We propose that nivation (snow-related) processes operated for much of that time, and again during the Younger Dryas Stadial (12.9 - 11.7 ka BP), and made a contribution to the lowering of the limestone surface by both mechanical and chemical action. Similar processes are likely to have operated for short periods on several occasions during the Holocene when, according to proxy records, climate deteriorated. We question previous views that dissolution occurred in an entirely temperate sub-regolith environment and/or was achieved solely by rainfall.
