This image shows an almost overcast double veil of Cirrostratus fibratus undulatus drifting over the location from the north (right side of the image). The double veil (variety duplicatus) consists of a whitish higher layer that has transverse waves on the southern (left) side (variety undulatus) and a lower layer that is particularly evident near the horizon where shading has occurred.
Several contrails are also present (for example, at 3 and 4).
A high pressure system maintained fine weather throughout the region.
Links in the image description will highlight features on the image. Mouse over the features for more detail.
The surface chart shows the situation an hour after the photo was taken. The region is under anticyclonic influence, with relative cold air and light winds in the lower troposphere. Northern Europe is dominated by a complex low pressure system that includes a series of weakening occluded fronts and a triple point front (the junction of a warm front, an occluded front and a cold front).
The sounding is from 6 hours earlier and 200 km upstream (to the east-north-east). It is deemed representative of conditions over Bad Kreuznach, Germany at the time of the image and shows high moisture content from 7 800 to 9 200 m.
The satellite picture shows the situation about two hours before the photo was taken. Most of middle and western Europe has clear skies under the influence of a large high pressure system. Over northern Europe, frontal cloud bands are streaming southward. North-western Germany is covered by high-level cloud.
