00:00Some places in Metro Manila were covered with fog earlier.

00:04But that's not all, because the wind is still blowing.

00:08Let's find out what happened to Dano Tinkongco.

00:15This part of Makati was almost unrecognizable this morning.

00:20It's the same in some places in Metro Manila.

00:22Is it foggy or foggy because of the upcoming Christmas?

00:26Not yet.

00:28According to what we saw in the video of the situation earlier,

00:32it's not foggy or foggy and foggy,

00:36but haze or pollution trapped in the wind

00:39that happened in Metro Manila before.

00:41Based on our upper air data,

00:43we had a thermal inversion this morning.

00:46So this means that our air is a bit hotter

00:50on a higher level of air.

00:53So 500 meters to be exact,

00:55the temperature is a bit higher

00:58compared to the temperature of the wind here at the lower surface level.

01:02And as a result, what happens is

01:04the air pollutants are trapped here on the ground.

01:08Supposedly, the wind here on the ground, on the surface,

01:12should be hotter.

01:15And then as you go higher, it should get colder.

01:18This has something to do with the end of the long wind

01:21or the wind coming from the northern part of the country.

01:25In this transition period before the Christmas,

01:28there is no or only a little wind in Luzon and Visayas,

01:31particularly in Metro Manila.

01:33That's why there is little or almost no wind

01:36that pushes smoke and pollution away.

01:38The result is haze, like what we experienced earlier.

01:42This usually happens when the wind is calm.

01:45Like now here in NCR,

01:47there is no strong wind that drives heat

01:51to our land.

01:52So the tendency is that the wind here at the lower surface

01:56gets colder

01:59compared to the wind at the upper surface.

02:02So what happens is that it gets trapped.

02:04It doesn't rise.

02:05It doesn't evaporate.

02:07According to the forecast,

02:08the haze usually disappears within 24 hours

02:11as long as the wind gets stronger.

02:13Following the transition,

02:15it is also expected that

02:16it will be possible on the second week of October

02:19until the second or third week of November.

02:24For GMA Integrated News,

02:25let's go to Kunko Nakatuto at 24 hours.
