AREA OF STUDY
Forest fire occurs quite oftenIn 1997-1998 ENSO event: 12 million hectares were burned causing more than US$ 9 billion economic loss
RATIONALES
Archipelago and montainous area
(NASA)
To simulate impacts of forest fire burning over the region
OBJECTIVE
CONTROL RUN
• 80 x 101• 55 km horisontal & 10 minute resolution• OISST & NNRP2 data set• LBC = relaxation• PBL = Holtslag• Fritsch & Chappell Convective closure• SUBEX large scale precipitation scheme • From 15 August 1997 to 1 October 1997
BIOMAS-BURNING RUN
• Constructed a data base of forest fire obtained from satellite images classify it as: No burning (0), Small burning (1), Medium burning (2), Heavy burning (3)
BIOMAS-BURNING RUN
• Constructed a data base of forest fire obtained from satellite images classify it as: No burning (0), Small burning (1), Medium burning (2), Heavy burning (3)
The satellite images are of August 17, 22, 24, 25 and 28 1997.
• Input the coded data of forest fire into the RegCM
• Run the tracer model with a change in optical property (absorbing aerosol – black carbon/soot)This is coded especially for this particular project
RESULTS
• Animation of the forest fire
• Shortwave radiation
• Cloud
• Air temperature
• Average temperature
• Average shortwave
Shortwave radiation (W/M2)

CONCLUSION
The model can capture:the transport and removal processdecrease of shortwave radiation reaching
the surface ; cooling of surface tropospheric warming effect of absorbing
aerosol (BC)influence on convection ??
