Review of Land Fires and Smoke Haze Situation for First Fortnight of September 2019
1.1 Under prevailing wet conditions, no significant hotspot activity was observed in the northern ASEAN region.
1.2 In the southern ASEAN region, prolonged dry weather in the first fortnight of September 2019 led to the significant increase in the hotspot activities, particularly over Sumatra and Kalimantan. Widespread moderate to dense smoke haze was observed to emanate from persistent hotspots detected in Sumatra and Kalimantan, and hazy conditions had shrouded many areas there during the fortnight period. Some of the smoke haze from Sumatra and Kalimantan had also been blown by the prevailing winds to affect Malaysia and Singapore.
Figure 1: Himawari-8 satellite image on 8 Sep 2019 shows smoke haze from hotspots detected in West, Central and South Kalimantan; some of the smoke haze had been blown toward the adjacent sea areas and western Sarawak.
Figure 2: Himawari-8 satellite image on 10 Sep 2019 shows smoke haze from hotspots detected in southern and central Sumatra; some of the smoke haze had been transported to affect Peninsular Malaysia and Singapore.
Figure 3: Aqua satellite image on 11 Sep 2019 shows widespread moderate to dense smoke haze from hotspots detected in southern and central Sumatra.
Figure 4: Aqua satellite image on 14 Sep 2019 shows widespread moderate to dense smoke haze from hotspots detected in Kalimantan.
