9 July 2001

The Meteorological Service of Singapore reports on 8 July 2001 for the South East Asian region: “Sumatra   remained relatively fair and dry for the past few days. Hot spots with slight smoke haze and plumes were detected in Sumatra and Kalimantan.” Forecasts of winds and surface pressure are also available.

Apart from brief periods of dry weather, the Southwest monsoon season in the region has been mostly wet up to third week of June 2001. However, weather conditions have become drier towards the end of June 2001 and into the first 3 days of July 2001. Consequently, hotspots counts over Sumatra and Kalimantan in May and June 2001 have been low with a large number of days with few or no hotspots detected. However, since the 1st July 2001, the number of hotspots has increased significantly from 81 to 154 on 2 July 2001 over Sumatra and from 14 to 77 over Borneo.

The ASEAN Fire Weather Information System (ASFWIS) is a co-operation between ASEAN and the Canadian Forest Service. It provides maps describing the current fire weather situation in South East Asia. This system is based upon the Canadian Forest Fire Danger Rating System (CFFDRS) (for further infomation to the CFFDRS refer to ASFWIS). Studies have shown that the CFFDRS is applicable outside of Canada. Currently it is also used in a modified form in New Zealand (see References). In New Zealand the Fire Weather Indices Fine Fuel Moisture Code (FFMC) and the Initial Spread Index (ISI) represent the fire danger in the scrublands. The Duff Moisture Code (DMC) is also applicable in South East Asia, because it potentially describes the moisture state of the upper peat layers in peat and peat swamp forests. All three parameters may serve as a suitable indicator of forest fire danger in South East Asia.

According to the ASFWIS for 6 July 2001 these parameters show various fire weather conditions over South East Asia:
