The High-Pressure Area of November 1889 in Central Europe, with Remarks on High-Pressure Areas in General

Abstract

UNDER this heading Dr. Hann, of Vienna, has recently had a memoir published,¹ in which he gives in detail and discusses the meteorological condi tions and circumstances in the high-pressure area which remained nearly stationary over the Alps and the circumjacent territory in November 1889, during fourteen days. On November 6 there was high pressure over the Atlantic Ocean, France, and the southern part of England. On the morning of the 11th the centre lay over the North Sea, and on the I2th it was transferred to Central Europe, and nearly the whole of Europe was comprised within the high-pressure area, which continued until the 25th. During this time there was low pressure over the extreme north-west, north, and north-east of Europe, but no distinct storm-centre up to and even beyond the 60th parallel of latitude. The centre of high pressure, 780 mm. reduced to sea-level, lay over the eastern part of the Alps. The wind, as shown by the chart, seemed to blow gently out from this centre, and at the same time to turn toward the right, indicating an anticyclonic motion. The charts also show that the region of high barometric pressure corresponded with that of low temperature, the latter, however, without any reduction to sea-level.
