The stations used by the forecaster for England are fifty- 
eight in number, and cover the whole of Western Europe, 
ranging from Bod6, within the Arctic circle, to the Azores, 
and from the coasts of Ireland to Berlin; and it may here 
be noted that the forecasts for the western side of this 
area present more difficulties than would be the case for 
Central and Eastern Europe, as in the main the weather 
in this hemisphere comes from the west, and no stations 
are available in the Atlantic. 
In these islands four types of weather systems are 
recognised :— 
1. The Southerly, in which an anti-cyclone lies to the 
east or south-east of Great Britain, while cyclones, coming 
in from the Atlantic, either beat up against it or pass 
towards north-east. 
2. The Westerly, in which the tropical belt of anti- 
cyclones is found to the south of Great Britain, and the 
cyclones, which are formed in the central Atlantic, pass 
towards east or north-east. 
3. The Northerly, in which the Atlantic anti-cyclone 
stretches far to the west and north-west of Great Britain, 
roughly covering the Atlantic Ocean. In this case 
cyclones spring up on the north or east side, and, either, 
work round the anti-cyclone to the south-east, or leave it 
and travel rapidly towards the east. 
4. The Easterly, in which an apparently non-tropical 
anti-cyclone (or one disconnected with the tropical high- 
pressure belt) appears in the north-east of Europe, rarely 
extending beyond the coast-line, while the Atlantic anti- 
cyclone is occasionally totally absent from the Bay of 
Biscay. The cyclones then either come in from the 
Atlantic and pass south-east between the Sandinavian and 
Atlantic anti-cyclones, or else, their progress being im- 
peded, they are arrested or deflected by the anti-cyclone in 
the north-east of Europe. Sometimes they are formed to
