Review of Regional Haze Situation for November 2024
1.1 Northeast monsoon conditions emerged over the ASEAN region during November 2024 as the prevailing low-level winds over the Mekong sub-region, Peninsular Malaysia, Singapore and the Philippines blew from the northeast or east. Light and variable winds were still observed over areas south of the Equator and the northern parts of the Mekong sub-region (Figure 1).
1.2 Drier conditions were observed over most parts of the Mekong sub-region except for isolated showers recorded over Myanmar and the southern parts of Viet Nam. Showers were observed over most parts of the southern ASEAN region with intense rainfall recorded over southern Thailand and the eastern coastal regions of Peninsular Malaysia where floodings were reported (Figure 1). Intense rainfall was also recorded in the northern parts of the Philippines under the influence of multiple Typhoons and Super Typhoons which led to floodings and landslides in the area.
1.3 The overall hotspot counts in 2024 over the ASEAN region were lower than or comparable to previous years, except for Viet Nam where the hotspot count was slightly higher.
1.4 Persistent isolated hotspots were mostly detected in the central parts of Thailand and Myanmar, as well as the northern and central parts of Viet Nam.
