Polusyong naipit sa hangin ang mala-hamog na naranasan sa Metro Manila kanina ayon sa... | 24 Oras

Summary

The video discusses the presence of haze in Metro Manila, attributed to a thermal inversion caused by a lack of strong winds. This weather phenomenon results in warmer air at higher altitudes, trapping cooler air and pollutants close to the ground, leading to reduced visibility. The video notes that this haze is not a result of smoke but rather a combination of pollution and weather conditions. PAGASA anticipates the arrival of the Amihan winds, which may alleviate the haze, expected to occur between mid-October and mid-November.

Takeaways

• 🌫️ Areas in Metro Manila experienced fog-like conditions this morning due to an approaching northeast monsoon.
• 🌡️ The weather phenomenon is caused by thermal inversion, where higher air temperatures trap cooler air at the surface.
• 🏙️ Foggy conditions in Metro Manila resembled those in Baguio, hinting at pollution mixed with natural fog.
• 🌪️ Weak winds in Luzon and Visayas are contributing to the accumulation of haze and air pollution.
• 🌀 The current calm weather is preventing the dispersal of smoke and pollution from the area.
• ⏳ The haze is expected to dissipate within four hours if stronger winds pick up.
• 🌬️ The northeast monsoon (Amihan) is anticipated to arrive between the second and third weeks of October.
• 📈 The phenomenon indicates a transition period as the southwest monsoon (habagat) ends.
• 🌍 Upper air data indicates a significant temperature difference between the air at surface level and at 500 meters high.
• 📺 This report is part of GMA Integrated News, providing timely weather updates.

Q & A

What weather phenomenon is currently affecting Metro Manila?

Metro Manila is currently experiencing haze, which is a combination of air pollution trapped in the atmosphere due to thermal inversion.

What causes the haze observed in Metro Manila?

The haze is caused by a thermal inversion, where warmer air at higher altitudes traps cooler air near the surface, preventing pollutants from dispersing.

What is thermal inversion, and how does it affect air quality?

Thermal inversion occurs when a layer of warmer air traps cooler air below it, leading to stagnant air conditions that can trap pollutants and cause hazy conditions.

What are the typical weather patterns in Metro Manila during this transition period?

During this transition period, there is usually little to no wind, especially before the onset of the Amihan, which leads to stagnant air and reduced dispersion of pollution.

When is the Amihan expected to arrive in Metro Manila?

The Amihan is expected to arrive in the second week of October and could last until the second or third week of November.

What is the relationship between the Habagat and Amihan winds?

Habagat is the southwest monsoon, while Amihan is the northeast monsoon. The transition from Habagat to Amihan often leads to calm wind conditions, contributing to haze.

How long does the haze typically last, and what can dissipate it?

The haze can last for about four hours but is usually dissipated when stronger winds develop, which help to disperse the trapped pollutants.

What visual evidence was noted in the transcript regarding the haze?

The transcript mentioned that visibility was significantly reduced in parts of Makati, resembling fog, indicating the severity of the haze.

What role does humidity play in the formation of haze?

High humidity levels can contribute to the formation of haze, as moisture in the air can mix with pollutants, creating a denser, more visible haze.

How does the absence of strong winds affect the pollution levels in Metro Manila?

The absence of strong winds leads to the accumulation of pollutants near the surface, worsening air quality and creating hazy conditions.
