This case has an appearance very close to the classical description.
The Warm Front cloud band can be observed over the Atlantic (just east of approximately 25W) extending to Northern Ireland. Several features mentioned above can be observed: Also, the relationship of the cloud band to the key parameters is very close to the ideal case (see Key parameters).

This case shows some deviations from the ideal cases.
The cloud band of the Warm Front can be located in the IR and WV images from Iceland across the Atlantic towards Norway. In the IR image it consists of several high, i.e. cold, cloud areas and cloud lines superimposed on dark grey, i.e. warmer, cloud tops. Over Iceland the mountains trigger some lee clouds, embedded by the Warm Front Band. In the WV image a broad white band in the area of the Warm Front indicates high water vapour content bounded by Dark Stripes on the northern as well as the southern edges. The northern stripe represents the dry air along the cyclonic side of the jet. The dark grey area extending over Great Britain is an extensive area of Fog and Stratus.
