The agency also warned that acid rain can be generated in areas where vog is present which “could damage crops and affect metal roofs and buildings.”The Philippine Atmospheric, Geophysical and Astronomical Services Administration clarified that the smog in Metro Manila is influenced by several factors: thermal inversion, high humidity, and calm wind conditions.thermal inversion happens when cool air is trapped by a warmer layer of air above it.
“Since warm air rises, air under the inversion cannot escape because it is cooler than farther aloft. Smoke and pollution get trapped,” the NWS said. PAGASA said inversion usually disappears later in the day but cloudy conditions allow haze to persist.
