    Many parts of England and Wales was gripped by an unusually prolonged spell of fog during November 1936. Pressure began to rise on the 18th and the first fogs formed on the 19th. At Manchester, visibility dropped to 600 yards on the 19th. From about 6.30pm on the 21st to about 10.40am on the 28th, visibilty at Manchester was constantly below 220 yards, a period of over 160hrs of continuous fog. On the evening of the 27th, visibility was down to 1 to 3 yards at one stage making even travel on foot nigh on impossible.

    With the great industries in and around Manchester, the fog became increasingly polluted and the fog became highly acidic with sulphurous compounds which irritated the respiratory system . The soot started to coated substances with a black wet slime, so much so that a number of cotton mills had to shut down because the fog was soiling the yarn.

    At Bournville, the fog preciptated a light drizzle which had a pH of 3.0 The acidicity of the fog was such that even in doors, silver and copper articles became tarnished. All surfaces outdoors such as pavements, grass etc became very sooty.

    It became unsettled as high pressure gave way to low pressure systems.

    Thank you, that's generally the case isn't it but I'd wondered if it was chased away by a more continental flow instead.
