The dense night and early morning fog engulfed parts of the United Arab Emirates (UAE) and northern Oman on both sides of the Hajar AlGharbi (western Hajar mountains).

Very low visibility was recorded at Adu Dhabi, Dubai, Al Ain, Fujairah, Sharja and Ras Al Kaiyma in the UAE and Muscat in Oman. At around 08:00 UTC the sky start to clear and fog dissipated.

This table shows how visibility was declining from the afternoon of 24 December to the morning of 25 December in some areas in UAE and Oman.

Fog over the Emirates and the adjacent Omani desert plain is not uncommon in the cold season. This time was rather exceptional because the Omani coastal plain facing the Sea of Oman, the Al Batinah plain, also experienced fog (see photo of fog from the Oman Daily Observer).

The animated sequence of the Meteosat-8 Night Cloud Microphysics RGB, 24 December 2017 15:00 UTC–25 December 07:00 UTC (MP4, 8 MB) shows the formation and dissolution of large fog patches from 24 to 25 December.

On the Night Microphysics animation the first silver-coloured patches started to form over the northern parts of the Emirates after sunset. While they extended southwards and inland, an elongated patch started to engulf the Al Batinah plain on the other side of the Hajar Al Gharbi (Figure 1, top right, click to expand). Other patches also formed over the Iranian coast.

At sunrise the silver-coloured area of the fog faded and changed into magenta coloured shades, due to the particular characteristics of the IR3.9 channel used in the RGB composites.

Soon after the colour change all the fog patches dissolved. Similar fog cycles were observed also in the days after 24-25 December (not shown).

The animated gif of the Meteosat-8 HRV with semi-transparent Natural Colour RGB overlaid, 25 Dec 03:00–06:00 UTC (Figure 2) shows more details of the fog evolution over the Al Batinah plain north west of Muscat.
