Fog in Pattaya not related to PM2.5 air pollution

By The Nation

 

 

The thick fog covering the eastern coast of Thailand is a natural phenomenon, the Centre for Air Pollution Mitigation said on Saturday.

 

 

Recent news of thick fog seen over Pattaya city on Friday had caused jitters among the people about PM2.5 air pollution.

 

The centre explained that the collision of hot and cold air masses together with high humidity had caused the fog in the areas.

 

"This fog will disappear when the temperature rises and it may occur again," the centre said.

 

The centre added that a portable air quality metre may show exaggerated results as it may read water vapour as dust particles.

 

"People can visit the centre's Facebook page for weather information, PM2.5 air pollution forecast and knowledge about air pollution, while they can report air pollution cases via the Pollution Control Department's hotline 1650," the centre added.

good to clear up that nonsense

This makes sense as I've been doing a lot of exercise and felt no difference in my breathing

The fog was because of the recent rain. As it warmed up during the day, the water started evaporating - like it always does.

I went for a ride towards Rayong yesterday and the same misty fog could be seen rising out of the trees and fields that whole way there and back. Nothing at all to do with the pollution (which would have mostly been knocked out of the air by the rain - like it always is).

I would expect to see similar misty fog today as well.

Can also be caused by the water in the ocean? LA beaches get foggy this time of year but not because of rain.

Yeah, it happens a lot when cooler air meets warmer waters and the evaporation condenses and becomes fog. Doesn't have to be that much cooler apparently, just enough to make the microscopic droplets condense. One article mentions a temperature difference of as little as 2.5 degrees between the "dew point" and the air temperature. Another says that fog will form with the air temperature is from 5-40 degrees cooler than the surface water temperature. 

LA has a massive smog problem though, even with all the pollution control regulations they've brought it (some of the strictest standards not just in the USA but in the world it seems). Add to that the warm water off the coast and cold air coming from (mainly) the north. 
I think the El Niño and La Niña cycles have an effect as well.

It is pm 2.5. see AQI and Ventuski.

Yep, the next morning the fog or smaze or smog had cleared, but the AQI was still 120 with high PM 2.5.

But of course, since the mess apparently scared off some tourists from visiting Pattaya, it has to be attributed to harmless natural phenomena.

Amazing Thailand, no Covid-19 here and completely free from air pollution too!

I might add that this agency benefits from good news on the pollution data. Before u start believing it, read this:

What LA did you guys grow up in?  The water off the coast is never warm in Southern Cal.  Maybe for about 6 weeks in July-August.  And fog season is in the Spring and early Summer, not the winter.

Lies, lies and more lies.

Seems some offices are not on the same agenda?

Please read up on the long term effects of air pollution. Much like smoking, all seems well short-term   but years down the road...

As usual, the "authorities" deny, deflect, ignore and corrupt. I suppose the 257 AQI in Bangkok was the same harmless fog as Pattaya's Thursday, AQI of 157.

The authorities have determined that the haze has nothing to do with pollution, and there is no prostitution in Pattaya.

you didn't read the article it seems

They should call them the Centre for Protecting Crop burning! 

Moisture in the air ,early morning dew burns off around noon time.

.

Jeez is this where we are at now? Everytime we have some 'weather' everyone soils themselves!! Get a grip. I really cant believe what society has become

I did not think pattaya suffered from this.Chiangmai yes,it made  the news pages  at lest

I pointed the BS detector to the screen displaying this article, and it started screaming, shaking, caught fire and emitted a puff of smoke, which surely has nothing to do with any kind of pollution. It must be conspiracy of all the air quality detector makers against the Pattaya authorities. Air quality detectors are all fake news, soon to be controlled items or banned.

Don't trust unreliable scientific instruments. Government spokesman are your best source of information. 

This site is reliable, and isn't showing any PM2.5 problem in Chonburi over this current weekend:

The same site reports values of over 100 for Pattaya and Bang Saray

As I’ve worked and lived in Beijing for a couple of years so my NOSE tells me what is what.

I left Pattaya yesterday after a week there, and I know what coal fired power plants smell like.

 

While the lower wisps were fog, the big smell is real pollution, only to get worse as burning season starts in Cambodia.

Much pollution in Nov also comes from the current sugar cane burning

AirVisual reports data from governmental and non-governmental monitors. All data are constantly monitored and validated by AirVisual cloud-based Artificial Intelligent (AI) system, which uses billions of air quality data points and pattern recognition to flag what it considers inappropriate.

 

Fog or pollution, choose who you wish to believe.

My nose told me the mist was from burning and my terrace told me to hose it down and clean the furniture. You would not believe the black sod I cleaned off my car's windscreen. This in NaJomtien.

My sore throat and my runny nose since 2 days confirm your statement

 

I bet the officials don't want to ''perturb'' the domestic tourists migration

during this 4 days holidays

 

Next (fake) news

The road are safe !! You can travel without any worries

 

the only problems minors that could occur, like hypothetics accidents with injuries or deaths

are only due to the fact few people are not wearing enough amulets around the necks
