Why does the smoke fluctuate?

[Lacessit]

Looking out from my condo 9.40 am in Chiang Mai, the smoke is as bad as I have seen it, and I can also smell it. Visibility is down to 500 metres.

I've observed during this season the smoke is worst in the morning. Visibility improves in the late afternoon. What is the explanation of this?

[CGW]

They burn at night, "less" chance of being caught? ????

Also "temperature inversion" will bring more pollution at night.

[orang37]

The  "Ockham's Razor" hypothesis for most significant factor (using aggregated data from the entire "burning  season") would be: winds change. Of course, the change in sheer volume/scope of burning comes into play.

 

~o:37;

[cmsally]

If it was only sporadic burning and inversion, I can;t see how the conditions could so radically change. It is looking more like there is some set schedule for agricultural burning that is clearly breaking the "no burning rule" . I don't believe nobody knows what is going on.

This should be a National Emergency,the untold damage to

peoples health,the effect on tourism,people's livelihoods,

and it's not a natural disaster that cannot be foretold,it

HAPPENS EVERY YEAR,and has done for years,with this

year been the worse..........and next year ?

[Happystance]

Atmospheric pressures coupled with the burning cycles.

 

Unbelievable it is allowed to continue.

[krey]

yeah i went south for a few days but had to come back, few days ago.  Was not that bad last couple of days but woke up to 389 in my area.  I been through a few seasons but this one seems extra bad.  In any case decided this is my last year up north, I know some people might say it is not that bad or I am a wimp for leaving but whatever I am not feeling well up here during these times, time to get out of dodge

Are you in CM?

It is never going to change as evidenced by the fact it has gotten worse with years of complaints.

 

I do not understand why people would stay there during this time.

 

If you know that in fact it is/will cause major health issues and possibly take years of your life why stay?

 

Families?  It affects children also big time their lungs are not even fully developed horrible for them.

I think school is out soon I would get out of town for as long as possible.

 

Older single people have no excuse unless I guess you have no money  CM airport goes just about any place I would leave for a few months and actually live life in a healthier environment....

I have lived in Chiang Mai for 31 years,not easy to live elsewhere at this time

have animals to look after,and family with jobs,"take years off your life",at 73

wonder how many i have left.

Every year I hear the Government say things are going to improve,the fact, they

get worse,words mean nothing, before the burning season next year,get the

police and army  up in the hills patrolling,hopefully they can catch some arsonists,  

and make an example of them, say 5 years in jail,these people are doing grave harm

to people's health,affecting the tourism industry and livelihoods.

 

They seem more serious about smoking a cigarette on the beach,and vaping,

can get you deported, set the forest a blaze........

Burning at night, smoke descends to valley floor.  Sun warms the air up & hot air rises, taking smoke higher, so cleaner air on valley floor.  Wind normally builds up in afternoon, clearing some smoke.  What I don't understand, is, if the smoke is from neighbouring countries, then surely that wind would replace the smoke blown away.

Noone in their right mind would criticize you for leaving. It's the intelligent thing to do.

Life circumstances and commitments are why people stay. No one wants to breathe that filth.

Easier said than done.

 

Which months are you talking? Feb-Apr?

Because I just read an analysis that CM air is actually only passable by international standards 3 or maybe 4 months of the entire year.

 

I feel sorry for those who can't get out. There is a lot of them. 

 

Myself, I gave up, scrapped my ED Visa and lease plans and ran. But not without emotional pain...

 

What a shame.

True.  Only time the air is good is during the rainy season.  Also, when we get a proper soaking by a big storm during the dry season.  Rest of the time, AQI is yellow or orange.  By late January, more often in Red zone.  Now we're in purple & brown ???? 

[tlandtday]

People need to understand the World Health limit for 2.5 is 20 so how does Thailand deal with levels above 20?  Simple they just raise the 2.5 safety level to 50 lol.

[elgenon]

The General can crack down on overstayers but cannot crack down on a segment of voters that have to be wooed by populist policies.

Called biting the hand that feeds you.

[dotpoom]

"They burn at night, "less" chance of being caught?"

   Would fire at night not be more visible than in the day time?

[cmsally]

There seems to be a pattern of more smoke at weekends. Presumably any officials that are meant to be responsible are not available at weekends, so less chance of repercussions.

Click me if you want to see a fire

[1FinickyOne]

a breeze... aa butterfly flaps its wings

[Fore Man]

Our maid came in today and reported that there was a large wildfire near her home  out in Saluang that was choking everybody living out there. That could well be the cause of the sudden rise in the AQI here in Mae Rim...444 at present. Even our three air purifiers can’t keep up with the load, and the best indoor PM 2.5 reading we have hovers around 100.

 

 But I have a question if anybody can answer it.  Does an air conditioner recirculate indoor air only, or does any exterior air get pulled into the dwelling?

Beyond me how this is not officially declared a national emergency.

Just a question: What would a national emergency involve? 

 

How would declaring one do anything?

Time to get out of Dodge! This will continue for an expected two more months or more. Forecasts are for the hottest and dry Summer on record!!

For starters, let’s assume that all national resources and the best minds would be combined into a problem-resolving team to overcome the issue at hand. This would also ostensibly provide the PM and other government officials, e.g., governors, with authority to mobilize military, police, public health, industrial and transportation capabilities and assets. Actually not a bad idea at all if the Thais want to save their homeland from the ravages of preventable, man-made pollution.

It would involve these readings of over 300-400 being in BKK and not CM.

temperature, pressure, wind etc. It will hang on a colder morning and dissapear later in the day being the hotter part of the day.

The hotter the burning the less pollution. Burning at night is much worse.

We have 149pm2.5 in kanchanaburi today. Big sugarcane fields and vegetable fields are currently burning. Like i said on another thread i battled wild fires on public land for just over 4hours completely alone 2 days ago lit by local officials that like to sell bamboo and this is done during a ban. The fire truck came out twice and wouldnt go in the jungle. Yeh, let the farang do all the hard work because greedy yocals want bamboo. (also illegal to take for selling)... This could be a world news story. I tell you i almost jumped out of the tractor and ran at one point but was trapped too much so just plowed through the trees and fire in the hopes i would make it out. pretty scary stuff. Local orbator, officials etc... idiots! They dont care about Thais, Thailand or the enviroment globally. Wastes of space and oxygen and destroying the planet for everyone yet dont ever dare complain about the negligence or these pricks will try burn down your house thats now happened 2times to us. Im not a pussy though and will take care of anything they try for the good of mankind!! (couple trophies pls?)..

[donim]

This looks far more worse than 500 meter sight..

Thanks for that , a touch of sarcasm but not your fault , I live halfway between the Chiang Rai 240 and the border 317.  Today at 10 am the worst it has ever been.

Trophy from me. Spot on unamazed , a couple of us go on our bikes every Weds. over the nearby mountains/hills.3 days ago one side of the mountain road had been torched only the road and an easterly breeze stopped the burning from going further. I think my TW has at last realised it is NOT smoke from Lao/Myanmar or every other country , it is the locals that just love to burn , it must be in their blood !
