- Images show cities from around the world shrouded in thick fog, making them almost disappear
- In December fog was seen suffocating London as heat rose from the ground and temperatures plummeted
- One city that looks particularly amazing when fog rolls in is Dubai, a skyscraper-heavy city in the UAE
These cities are usually easily distinguishable from their iconic skylines.
However, after being shrouded in a thick carpet of fog, they are a little more difficult to make out.
From San Francisco to Shanghai, these incredible images show what happens when freak weather rolls in and swallows skyscrapers whole, leaving the tips meekly poking out from an ocean of mist.
This December, fog descended on the UK capital with the Walkie Talkie and Gherkin among the skyscrapers shrouded in thick mist.
It made for a spectacular, if eerie, sight.
Here MailOnline Travel rounds up a selection of some of the most extreme foggy cityscapes from around the world.

WHAT IS FOG?
The official definition of fog is a visibility of less than 3,281 feet (1,000 metres).
This limit is appropriate for aviation purposes, but for the general public and motorists an upper limit of 591 feet (180 metres) is more realistic.
Fog is caused by tiny water droplets suspended in the air. The thickest fogs tend to occur in industrial areas where there are many pollution particles on which water droplets can grow.
Fogs that are composed entirely or mainly of water droplets are generally classified according to the physical process that produces saturation or near-saturation of the air.
The main types of fog are radiation fog, valley fog, advection fog, upslope fog, evaporation fog and freezing fog.
The title of foggiest place in the world goes to an area of the Atlantic Ocean called ‘Grand Banks’, lying off the coast of Newfoundland.
The area forms the meeting place of the cold Labrador Current from the north and the much warmer Gulf Stream from the south. This mixture of currents regularly causes fog to form on 200 days of the year.
