Thread: Bangkok shrouded in mysterious smog late Wednesday night

Many people in and around Bangkok reported the smell of burning late Wednesday night, as the city became shrouded in smog, with the amount of PM2.5 exceeding the 37.5 micron (µg/m³) threshold in 47 of the capital’s 50 districts.


The three districts most affected by PM2.5 dust were Don Mueang (143.5µg/m³), Lak Si (143µg/m³) and Bang Sue (139µg/m³), according to Geo-Informatics and Space Technology Development Agency (GISTDA).


The “Smell of something burning” hashtag on “X” was top trending late last night.


Pornphrom Vikitsreth, an advisor to the Governor of Bangkok, offered three possibilities to explain the presence of unusually thick smog.


The first is that the wind last night was unusually blowing onshore from the Gulf of Thailand and many hotspots were discovered around Bangkok.


The second possibility is that a summer storm, combined a high pressure cell from the north-eastern region, resulted in an increased accumulation of pollutants in the atmosphere.


The third is increased moisture in the atmosphere, resulting in an increased accumulation of PM2.5 in the air.


Last night, Thai PBS reporters went to several locations in Bangkok to investigate. They reported the sighting of thick smog in front of Kasetsart University.


An assistant at a petrol station on Vibhavadi Rangsit Highway said that he smelt burning at about 9pm before he saw “thick smoke”.


PM2.5 levels in seven central provinces exceeded the safe threshold level last night, including Nonthaburi (113.4µg/m³) and Pathum Thani (107.6µg/m³).


According to the Bangkok Metropolitan Administration’s Air Quality Information Centre, excessive PM2.5 was reported this morning in many areas of Bangkok, with Lat Krabang (57.5µg/m³) being the worst hit.

Does high humidity cause poor air quality?
Humidity has an impact on the formation and dispersion of air pollutants. Humid air traps pollutants close to the ground, preventing them from dispersing into the atmosphere. This increases the concentrations of pollutants in the air, especially in urban areas.

Thanks.

So, 'humidity' rather than merely 'moisture', which obviously includes rain.

People also ask
Is humidity the same as moisture?

Moisture is nothing but the water vapour present in the air. Humidity also denotes the amount of water vapour present in a volume of air considered. Generally speaking, humidity is mainly used to talk about the moisture (amount of water) in the air.

Rain is moisture condensated

^Correct.

Of course it's a part of moisture.


Some light rain just started here.

That's twice in three days the forecasters have actually got it right.

When water condenses in the environment it does so on the surface that the environment provides it, be it structures or dust particles
When water particles condense on dust particles present in the air, mist is formed. Mist is the phenomenon caused by the suspension of small drops of water present in the air. (GCSE physics.)

Cooler air moving in from the gulf may have lowered the air temperature slightly, but enough to cause the water vapour in the humid air to condense around the dust particles already present thereby forming the mist.

Your onto it Mr dentist

They say that in France, women having PreMenstruel syndrom, can't be convicted of a crime.

With that in mind, I guess that Reg's offense, could be forgiven.
