Bijhorende tekst, het H is op de figuur wel iets te oostelijk ingetekend. Maar voor de rest min iof meer de situatie waarin we de laatste twee dagen vertoeven, alhoewel er toch ook op hogere nivo's bewolking voorkwam.
To get extensive sheets of stratocumulus over the North Sea without any cloudiness above, there should be an anticyclone over Great Britain. Crucial for the Sc sheets is a temperature inversion and the presence of sufficient moisture along with some updraft to form cloudiness (unstable air in surface layer). With a north-westerly flow these Sc sheets will penetrate the Netherlands. Mostly the high pressure over England is a blocking high of one of the following types:
* either a diffluent blocking, when there is a corresponding low south of England;
* an omega blocking, when there is a low west of Ireland and a low over central Europe.
