Heat release from the surfaceĪnother fact that you might be interested in learning is that the heating of the surface from the sun is what causes the air temperature to increase. You might understand that there is vertical motion in the atmosphere since you can actually see the definition of the clouds, but how does this occur at the ground? A foggy road with low visibility. Condensation occurs when the air temperature and dewpoint temperature (the temperature at which condensation forms) are the same value. The cooling of the water vapor results in condensation, which is the transition of a gas (water vapor) to a liquid (cloud droplets). Clouds are composed of small water droplets or ice crystals and are formed when water vapor is transported vertically and cooled. The first factoid is that fog is just clouds at the ground. Fog is just a fancy word for clouds at ground level Are you ready to be a fog expert? Let’s go. Have you ever been driving down a road in the early morning hours and noticed that fog develops almost at random? Did you know that there are different types of fog? Today, you are going to learn more facts about fog than you knew existed. Heavy fog was, after all, a common occurrence in London and there was, according to most reports, no immediate sense of urgency to this smog event.(WKBN) – A common scene in the morning during summer months is early morning fog, and that has been no different this year in the Valley. Initially, the British government was slow to act during the Great Smog. Eleven prize heifers brought to Earls Court for the famed Smithfield Show choked to death, and breeders fashioned improvised gas masks for their cattle by soaking grain sacks in whiskey.Īfter five days of living in a sulfurous hell, the Great Smog finally lifted on December 9, when a brisk wind from the west swept the toxic cloud away from London and out to the North Sea. The effects of the Big Smoke weren’t limited to people: Birds lost in the fog crashed into buildings. Many experts now estimate the Great Smog claimed at least 8,000 lives, and perhaps as many as 12,000. The detrimental effects lingered, however, and death rates remained well above normal into the summer of 1953. Initial reports estimated that about 4,000 died prematurely in the immediate aftermath of the smog.
The death rate in London’s East End increased ninefold. Deaths from bronchitis and pneumonia increased more than sevenfold. It wasn’t until undertakers began to run out of coffins and florists out of bouquets that the deadly impact of the Great Smog was realized. Heavy smokers were especially vulnerable because of their already-impaired lungs, and smoking was common at the time, especially among men. It was lethal, particularly for the elderly, young children and those with respiratory problems. The Great Smog of 1952 was much more than a nuisance.
Fog weather movie#
A greasy grime covered exposed surfaces, and movie theaters closed as the yellow haze made it impossible for ticket-holders to see the screen. The smog seeped inside buildings as well. Weekend soccer games were cancelled, although Oxford and Cambridge carried on with their annual cross-country competition at Wimbledon Common with the help of track marshals who continually shouted, “This way, this way, Oxford and Cambridge” as runners materialized out of the thick haze.
By the time they returned home, their faces and nostrils blackened by the air, Londoners resembled coal miners. Wheezing pedestrians groped their way around the city’s neighborhoods and tried not to slip on the greasy black ooze that coated sidewalks.
Fog weather drivers#
Many found the effort futile and simply abandoned their cars.Ĭonductors holding flashlights walked in front of London’s iconic double-decker buses to guide drivers down city streets.
Fog weather windows#
Even during the middle of the day, drivers turned on their headlights and hanged their heads out car windows to inch ahead through the thick gloom. Flights were grounded and trains cancelled. For five days, the Great Smog paralyzed London and crippled all transportation, except for the London Underground train system.īecause of poor visibility, boat traffic on the River Thames came to a halt. The smog was so dense that residents in some sections of the city were unable to see their feet as they walked. The noxious, 30-mile-wide air mass, teeming with acrid sulfur particles, reeked like rotten eggs-and it was getting worse every day. The temperature inversion prevented London’s sulfurous coal smoke from rising, and with nary a breeze to be found, there was no wind to disperse the soot-laden smog.
