3. Meteorological Observations on Storms of Wind in October, November, and December of 1863

Extract

The author had traced eleven distinct storms of wind passing over parts of Europe, between the 26th October and 18th December. With the view of ascertaining the state of the atmosphere during the progress of these storms, in respect of pressure, temperature, wind, cloud, and rain, he had collected observations from all parts of Great Britain and Ireland, as well as from many places on the Continent. He found that each storm was marked by concentric circles of equal atmospheric pressure.
