Rimmer Posted November 15, 2006 Posted November 15, 2006 What is the haze that is hanging over the whole town and surrounding area at the moment, it is very noticable if you drive out of town a little and look across the fields. Reminds me a lot of the Indonesian smoke haze that hits Singapore and Malaysia every year in September. As the wind is mostly coming from N E maybe they are burning the fields up country. Can't be good to breath it, makes me cough

Rimmer Posted November 15, 2006 Author Posted November 15, 2006 Fire in a hotel in pattaya:http://www.thaivisa.com/forum/index.php?showtopic=92776 Nah it's been here for two weeks now but you need to get out of town to see how bad the air quality really is.

Can't be good to breath it, makes me cough No. What we see is being caused by a temperature inversion. In weather terms this means an increase in temperature with height. This 'inversion' leads to pollution, such as smog and dust and diesel fumes, being trapped closer to the ground, especially when the lower air is more humid. You can imagine how people's health will be affected...hence the coughing Rimmer. Also, at dusk or dawn at this time of the year i.e. when the sun is much lower in the sky, the heat radiated from Pattaya is far greater than that absorbed from the lower angled sun. The air becomes stiller and the air becomes murky because dust and pollutants are no longer lifted into the atmosphere. From my lofty perch, I can see the ribbon of black diesel fumes stretching the length of the Sukhumvit Road at about 06.30 these mornings....and as for Pattaya, well it is covered in an unmoving, dark grey blanket of baht bus smog.

Artisan Posted November 16, 2006 Posted November 16, 2006 Just another connected observation. Have you noticed on Loy Khratong, this year and last year, especially in the early evening, that the kom loys (floating lanterns) speed upwards and then slow down and usually reverse their direction of travel, even if there is some directional air movement at ground level. Once again, a temperature inversion is the cause causing the density of the warm air in the kom to become nearly equal to that of the warmer air higher up...the kom is stuck at a certain altitude!!!
taxexile Posted November 16, 2006 Posted November 16, 2006 you might be onto something there artisan. the haze in hua hin is such that if i look straight upwards , i can see blue sky and at night the stars are visible , but if i look straight ahead , the visibility is about a couple of kilkometeres , (today its a bit clearer ), and i'm just looking into something like a misty english autumn day. it only seems to be hazy up to a height of a few hundred metres , and even though there is some breeze , it isnt blowing away.
Artisan Posted November 16, 2006 Posted November 16, 2006 you might be onto something there artisan. Yes Taxexile........there is no doubt that is the reason. The same phenomenon that you are seeing in Hua Hin is being caused by an inversion. These inversions are common at this time of year and, although the rainy season has come to an end, the air is still very humid because of the blanketting effect of the warmer air higher in the atmosphere.

Sleep well and enjoy your lie-ins Wow Artisan that's serious, thanks for that I knew someone would have the answer. I remember reading that diesel engine soot is one of the worst polutants around, no wonder we all got coughs up here in VTV Any chance of a picture of the ribbon of fumes above the highway and the city next time you are looking down on it ?
Artisan Posted November 16, 2006 Posted November 16, 2006 (edited) Any chance of a picture of the ribbon of fumes above the highway and the city next time you are looking down on it ? Sure Rimmer...I'll try tomorrow. BTW...Jomtien Beach, and Jomtien in general, are always clear and don't suffer from the same dirty blanket of air pollution when we have these inversions..

Artisan thats very interesting we are experiencing a lot of smokey haze here in Phuket.. I thought it might have been some of Indoneasias smoke drifting up, but from what you say its quite natural this time of year.. Thank you for a very interesting answer..

Sorry, Rimmer.....I was awake with the dawn but inversion condition, although visible, was not distinct enough for photography. Watch this space though.

That's life Maybe tomorrow, be worth seeing if you can get it. Don't want you to loose any beauty sleep though waiting for the right conditions
Mobi Posted November 17, 2006 Posted November 17, 2006 No inversions out here in peaceful, sweet smelling Pong. Anyone want to rent one of the Mobi mansion poolside guest rooms?
Rimmer Posted November 17, 2006 Author Posted November 17, 2006 No inversions out here in peaceful, sweet smelling Pong.Anyone want to rent one of the Mobi mansion poolside guest rooms? Only if it's NOT got IPStar/CSloxinfo in it
Artisan Posted December 4, 2006 Posted December 4, 2006 Some recent pictures of the early morning SMOG over Pattaya caused by recent inversions. I've seen very much worse though.
Rimmer Posted December 4, 2006 Author Posted December 4, 2006 The first one is really bad. Looks like the trees are keeping the area above them clear, can that be or is it just because it's close?
Artisan Posted December 4, 2006 Posted December 4, 2006 (edited) The first one is really bad. Looks like the trees are keeping the area above them clear, can that be or is it just because it's close? Yes Rimmer. The trees in the foreground are very close and the density of the pollution is more apparent looking parallel to the ground. Also, from my viewpoint, there are very few diesel burners in the area. Wait until I catch an early morning inversion that makes the buildings of Pattaya completely disappear in a dark grey sea of pollution. Edited December 4, 2006 by Artisan

Hi Rimmer, Yesterday, late in the afternoon 5.30 p.m., there was the mother of all inversions which caused a huge smog blanket over the Sukhumvit Road (viewed in South Pattaya looking from Jomtien) stretching way across into Pattaya. Have a look at the pollution trapped below the inversion...it was horrendous..
