Open Access week – and atmospheric effects of solar eclipses
Next week is ‘Open Access Week’ , and to celebrate this, all Royal Society journal content will be completely free to access from Friday 21 October until 6 November.
Solar eclipses rarely cross populated regions, but provide great opportunities both for science and science outreach when they do. The recent 20 March 2015 solar eclipse tracked across the Atlantic, giving substantial solar radiation changes in the UK and Iceland, and totality in the Faeroes. This Theme Issue of the Philosophical Transactions of the Royal Society brings together a unique series of studies on effects of eclipses on the weather, placed in the context of societal responses to eclipses. Professor Giles Harrison from this department was joint lead editor on the issue, and the journal includes contributions from many members and ex-members of the Department of Meteorology at the University of Reading on a very wide variety of topics.
Investigating effects of eclipse-induced weather changes (e.g. in surface air temperatures, wind and cloud amount) has a long history, usually exploiting observations made during the eclipse for comparison with comparable non-eclipse conditions the day before or after. New approaches to study the weather-related changes are now possible, employing high resolution numerical models of the atmosphere in which an eclipse can be turned on or off at will, combined with the extensive coverage of good quality amateur and professional weather data available. This issue includes work analysing surface, balloon and satellite observations, alongside high resolution numerical modelling studies. In doing so it defines a new interdisciplinary research area in eclipse weather, closely focussed in scope, but diverse in the work it contains.
