Rains clear the air in SE Asia, raising hopes in smog crisis

Kuala Lumpur — Rain and favourable winds have brought clear skies to vast areas of Southeast Asia stricken for weeks by hazardous smoke from Indonesian fires, with officials expressing hope Thursday that the crisis could end soon.

Parts of Indonesia, Malaysia and Singapore enjoyed the cleanest air in weeks, while affected areas of the Philippines and Thailand also have seen an end to pollution that has sickened tens of thousands and caused flight cancellations and school closures.

Malaysia's top weather forecaster went so far as to declare that the region's rainy season was beginning.

Some experts have previously warned the El Nino weather phenomenon could delay the rains for months, prolonging the environmental disaster.

"The northeast monsoon has arrived. It is the raining season for Malaysia," said Che Gayah Ismail, director general of the country's meteorological department.

"We should have blue skies and no more haze because the northeast monsoon winds will blow the haze from Indonesia's forest fires into the Indian Ocean," she told AFP.

Indonesian authorities were more guarded, but also said further rains were expected.

Recent rainfall on the huge islands of Sumatra and Borneo — where hundreds of forest and agricultural fires have smouldered for weeks — have helped reduce the smoke clouds, said Indonesia's disaster agency spokesman Sutopo Purwo Nugroho.

Affected communities "welcomed this with joy and said grace after two months of being held captive to haze", Sutopo said in a statement.

The rains there included both natural precipitation and artificially induced showers from cloud-seeding, he added.

Indonesia's national weather agency has forecast more rain, which will allow for more cloud-seeding activities, Sutopo said.

The fires and the resulting haze occur to varying degrees annually during the dry season as land is illegally cleared by burning, stoking tensions between Indonesia and its smog-hit neighbours Malaysia and Singapore.

But experts had warned this year's outbreak was on track to become the worst yet, exacerbated by El Nino's bone-dry conditions.

The US-based World Resources Institute said earlier this month that the fires were spewing more greenhouse gases into the atmosphere each day than the United States, the world's second-largest emitter of the gases blamed for global warming.
