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 within the second half of the year 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.

Review of Regional Weather and Smoke Haze (Meteorological Service of Singapore2 September 2002) Mostly dry weather conditions were observed over Kalimantan and parts of central and southern Sumatra since the beginning of August 2002. As a result, the number of hotspots over Sumatra and in particular, over Borneo went up to more than 380 and 1,200 respectively in the 14 – 18 Aug 2002 period.
Daily hot spots counts over Kalimantan and Sumatra from 1July to 18 August 2002
NOAA-12 satellite pictures between 16 and 18 August 2002 overBorneo indicated widespread moderate to thick smoke haze covering most parts ofKalimantan, with the smoke haze spreading over the southern half of Sarawak andparts of the southern South China Sea (see: Smokeand hotspots over Borneo on 18 Aug 2002). In Sumatra, whilethe situation is not as serious, increased smoke haze have also been observed.The prevailing south-westerly wind has blown some smoke haze over PeninsularMalaysia and Singapore (see Hotspot/SmokeHaze over Sumatra on 17 Aug 2002).
Mostly weak El Niño conditions prevailed during July and August 2002, with sea-surface temperature (SST) anomalies remaining greater than 1°C throughout the central equatorial Pacific between 170°E and 120°W (left image). The Southern Oscillation Index (SOI) has been negative values since March 2002 (right image).

Weather and Haze Outlook (MeteorologicalServices Division of Singapore 2 September 2002)
“Most coupled modeland statistical model forecasts indicate that El Niño conditions are likely tocontinue through the end of 2002 and into early 2003. While there isconsiderable uncertainty in the forecasts about the timing and intensity of thepeak of this warm episode, all of the forecasts indicate that it will be muchweaker than the 1997-98 El Niño. Thus, it is likely that the global impacts ofthis warm episode should be correspondingly weaker than those observed duringthe very strong 1997-98 El Niño. With the above assessment, a weak toat most moderate El Niño is expected to persist in the next 6 to 9 months. Withthe current SW Monsoon season, drier-than-average conditions can be expectedover Indonesia, particularly in southern Sumatra and Kalimantan in the next 2months. While widespread prolonged dry weather conditions and severe smoke hazeare not likely for the rest of the year, periods of slight to moderate haze areexpected in the region. Occurrences of moderate to thick smoke haze canalso be expected over some parts of southern Sumatra and Kalimantan should dryweather conditions continue prevail.”

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.
The updated ASFWIS maps show fire weather, fuel conditions andfire behaviour parameters for South East Asia:
