Mark record


Development of the Drought Code component of the Canadian Forest Fire Behavior System is described. The scale of available moisture used in the original Stored Moisture Index developed for coastal British Columbia was transformed to one of cumulative drying and incorporated as a component of the National Index. Drought Code values are related to availability of surface water, and to fire behavior and effects. Procedures are developed for improving estimated starting values, taking into account the carry-over of drought from the previous season.
