The Meteorological Service of Singapore reports on 24 June 2002 for the South East Asian region: “Hot spots with smoke plumes were observed in Sumatra. Isolated hot spotswere also detected in Peninsular Malaysia. ” Forecasts of winds and surface pressure are also available.

Review of Regional Weather and Smoke Haze Some pockets of dry weather have started to develop over northern and central Sumatra and over a larger part of the northern half of Borneo in January as the northeast monsoon rain-belt progresses further south of the Equator over Southern Sumatra and Java island. The number of hot spots, however, was small on most days. (SOURCE: Meteorological Service of Singapore)

Weather and Haze Outlook Tropical Pacific Ocean sea surface temperatures (SSTs) were near normal to slightly above normal in September 2001. Most forecasts of advanced centres indicate SSTAs to increase slightly to above normal (+ 0.5º C ) by the end of the first quarter of 2002. This could indicate the possibility of the onset of a weak El Nino episode in the second half of 2002. The region is expected to transit from the current Southwest Monsoon Season to inter-monsoon conditions in October and November. While brief periods of dry weather could still occur, particularly over southern Sumatra and Kalimantan in October 2001, most parts of the region should begin to experience increased thundery shower activities in the coming months. These should bring about an end the potential of any smoke haze in the region for the rest of 2001.
The Meteorological Service of Singapore provides rainfall-record charts for selected locations in Sumatra and Kalimantan with information about the mean annual rainfall and the actual monthly and weekly records for last year.

The ASEANFire Weather Information System (ASFWIS) is a co-operation betweenASEAN and the Canadian Forest Service. It provides maps describing the currentfire weather situation in South East Asia. This system is based upon theCanadian Forest Fire Danger Rating System (CFFDRS) (for further infomation tothe CFFDRS refer to ASFWIS). Studies have shown that the CFFDRS is applicableoutside of Canada. Currently it is also used in a modified form in New Zealand(see References). In NewZealand the Fire Weather Indices Fine Fuel Moisture Code (FFMC) and the InitialSpread Index (ISI) represent the fire danger in the scrublands. The DuffMoisture Code (DMC) is also applicable in South East Asia, because itpotentially describes the moisture state of the upper peat layers in peat andpeat swamp forests. All three parameters may serve as a suitable indicator offorest fire danger in South East Asia.
According to the ASFWIS for 22 June 2002 these parametersshow various fire weather conditions over South East Asia:

South East AsiaFire Monitoring by ANDES The Asia Pacific Network for Disaster Mitigation using Earth ObservationSatellite (ANDES) provides daily fire maps of mainland and insular South EastAsia. The latest maps can be accessed through the ANDESwebsite. The map below shows the latest fire map of mainland SE Asia(Thailand, Myanmar, Lao, Cambodia, Viet Nam).

The Forest Fire Prevention and Control Project (FFPCP) The Forest Fire Prevention and Control Project (FFPCP) in Palembang (Sumatra) closed on 30 November 2001. The South Sumatra Forest Fire Management Project (SSFFMP) is expected to start in June 2002 and will continue the work of FFPCP. Meanwhile the daily fire map (hot-spot) and monthly drought index for Sumatra will continue to be updated from time to time. The last map is dated 23 June 2002.

Haze Prevention Group The industrial initiative to combat haze in SE Asia started to develop a website in February 2002. The website will include information about the objectives of this industrial initiative and the projects that are implemented to reduce wildfires and haze in pilot projects in Indonesia.
