“…Aplin & Harrison (2003) reviewed meteorological changes during solar eclipses, such as the often-observed reduction in surface temperature, but also wind speed and direction effects. Wind speed changes reliably reported include a substantial gust just after Fourth Contact (Anderson & Keefer 1975;Eaton et al 1997), possibly arising from transient turbulent mixing (Winkler et al 2001). During the August 1999 eclipse, a variation in wind direction was suggested in the observations of Aplin & Harrison (2003) at Reading and Camborne in the UK, apparently consistent with cyclonic (anticlockwise) circulation changes predicted from the cold-cored eclipse cyclone model of Clayton (1901).…”

Responses in surface winds to solar eclipses have an almost mystical status but are difficult to detect in observations because of their transient nature. High spatial resolution (approx. 1.5 km grid) meteorological models now provide a new technique for their investigation. Measurements from the southern UK meteorological network during the 11 August 1999 total solar eclipse are compared with a high-resolution model ignorant of the lunar shadow's influence. Differences between the model output and measurements at the eclipse time show transient eclipse zone temperature decreases of up to 3• C, which also depressed the day's maximum temperature compared with the model prediction. Coherent responses in temperature, and wind speed and direction measurements are detected in the inland cloud-free region (from 51• to 52• N and −2 • to 0 • E). A mean regional wind speed decrease of 0.7 m s −1 during the maximum eclipse hour is apparent with a mean anticlockwise wind direction change of 17• ; no such changes occurred in the model output. Such regional circulation changes are consistent with Clayton's 1901 cold-cored eclipse cyclone hypothesis, which may be related to the anecdotal 'eclipse wind'.

“…Unfortunately, the eclipse itself was partly obscured by cloud. There are numerous other accounts, both quantitative and qualitative, of meteorological effects observed during solar eclipses, three examples being the fall in air temperature of 1.5 • C during a total eclipse in southern Iraq on 25 February 1952 [2], a fall of 3 • C during the total eclipse in southern Sweden on 30 June 1954 [3] 1 and a fall of 3.5 • C accompanied by a reduction in wind speed of 4.5 m s −1 in Chinguetti, Mauritania, during the total solar eclipse of 30 June 1973 [4]. More recently, the meteorological effects of the total eclipse of 11 August 1999 in the UK and central Europe have been described in detail, and compared with modelled atmospheric conditions with and without the effects of reduced solar radiation [5][6][7][8][9][10], and references therein], while Aplin [11] reviews other related eclipse studies relating to atmospheric measurements.…”

“…Solar eclipses have inspired several earlier investigations in the field of meteorology. Surface atmospheric pressure fluctuations have been observed in connection with solar eclipses caused by the cooling of the atmosphere during the eclipse shadow period (Anderson et al, 1972;Anderson and Keefer, 1975). The pressure perturbations and induced gravity waves generated by a solar eclipse have been studied for several eclipse events (e.g.…”

Abstract. On 20 March 2015, a total solar eclipse occurred over • N, 11.9 • E), Svalbard, in the high Arctic. It was the first time that the surface radiation components during the totality of a solar eclipse were measured by a Baseline Surface Radiation Network (BSRN) station. With the Ny-Ålesund long-term radiation data set as background (available at doi:10.1594/PANGAEA.150000), we present here the peculiarities of the radiation components and basic meteorology observed during the eclipse event. The supplementary data set contains the basic BSRN radiation and surface meteorological data in 1 min resolution for March 2015, and is available at doi:10.1594/PANGAEA.854326. The eclipse radiation data will be a useful auxiliary data set for further studies on micrometeorological surface-atmosphere exchange processes in the Svalbard environment, and may serve as a test case for radiative transfer studies.
