The Keetch Byram Drought Index(KBDI) provides a daily measure of soil dryness, which, in turn, gives an indication of water stress in plants. The KBDI represents the net effect of precipitation and evapotranspiration in producing cumulative moisture deficiency in deep duff or upper soil layers. The KBDI has a range from 0(no drought or soil moisture deficiency, i. e. soil at field capacity) to 2000(extreme drought, maximum soil moisture deficiency possible). The index can be viewed as the amount of rain needed to bring the soil back to saturation, with one mm of rain reducing the index by 10 points. The 0-2000 point scale is divided into three drought classes : 0-999=Low; 1000-1499=Moderate; 1500-2000=High. The KBDI is simple to calculate as it uses only two, daily weather observations-maximum temperature and 24-hour rainfall. The system functions in a book-keeping fashion where estimates of daily evapo-transpiration and measurements of precipitation increase or decrease the value of yesterdays index. The KBDI by itself is not a Fire Danger Rating System as it gives no indicate of the ease of ignition of the vegetation, or of the rate of fire spread, fire intensity and difficulty of control. It does however serve as a useful measure of drought occurrence.  7, record 2, English, - Keetch%2DByram%20drought%20index

Keetch-Byram Drought Index (KBDI): ... 0 - 200: Soil moisture and large class fuel moistures are high and do not contribute much to fire intensity. Typical of spring dormant season following winter precipitation. 200 - 400: Typical of late spring, early growing season. Lower litter and duff layers are drying and beginning to contribute to fire intensity. 400 - 600: Typical of late summer, early fall. Lower litter and duff layers actively contribute to fire intensity and will burn actively. 600 - 800: Often associated with more severe drought with increased wildfire occurrence. Intense, deep burning fires with significant downwind spotting can be expected. Live fuels can also be expected to burn actively at these levels.  9, record 2, English, - Keetch%2DByram%20drought%20index

The Palmer Index was developed by Wayne Palmer in the 1960s and uses temperature and rainfall information in a formula to determine dryness. It has become the semi-official drought index. The Palmer Index is most effective in determining long term drought-a matter of several months-and is not as good with short-term forecasts (a matter of weeks). It uses a 0 as normal, and drought is shown in terms of minus numbers; for example, minus 2 is moderate drought, minus 3 is severe drought, and minus 4 is extreme drought. ... The Palmer Index can also reflect excess rain using a corresponding level reflected by plus figures; i.e., 0 is normal, plus 2 is moderate rainfall, etc.  8, record 3, English, - Palmer%20drought%20severity%20index

On calcule plutôt l'évapotranspiration à l'aide de formules empiriques comme celle de Thornthwaite, de Penman ou de Turc. On distingue l'évapotranspiration potentielle (ETP) qui est le pouvoir évaporant de l'atmosphère sur un sol avec couvert végétal disposant de l'eau en abondance. L'évapotranspiration réelle (ETR) correspond à la perte en eau d'un sol quand l'eau vient à manquer: l'ETR est fonction de l'ETP et de la quantité d'eau présente dans le sol.  3, record 4, French, - formule%20de%20Turc
