Subject field(s)
  • Climatology
DEF

An index used to gage the severity of drought conditions by using a water balance equation to track water supply and demand.

CONT

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.

CONT

Palmer Drought Severity Index(PDSI)... compares the actual amount of precipitation received in an area during a specified period with the normal or average amount expected during that same period. It was developed to measure lack of moisture over a relatively long period of time and is based on the supply and demand concept of a water balance equation. Included in the equation are amount of evaporation, soil recharge, and runoff and temperature and precipitation data.

CONT

PALMER DROUGHT INDEX [is] a long-term meteorological drought severity index produced by the NOAA/USDA (Department of Agriculture) Joint Agricultural Weather Facility [that] depicts prolonged times, as in months or years, of abnormal dryness or wetness [over large regions]. It responds slowly, changing little from week to week, and reflects long-term moisture runoff, recharge, and deep percolation, as well as evapotranspiration.

CONT

Literature describing the suite of indices for measuring drought that are collectively known as "PDI"; including the Palmer Drought Severity Index (PDSI), Palmer Hydrologic Drought Index (PHDI) ...

OBS

The Palmer Index has long been used by the agriculture community to anticipate the potential effects of weather on crop development and yield.

OBS

Palmer Drought Index [is] published periodically by the Joint Agricultural Weather Facility.

OBS

... this [PDSI] index is calculated weekly by the National Weather Service [(United States)].

French

Domaine(s)
  • Climatologie
CONT

Il est donc évident que les États-Unis reçoivent plus de pluies, plutôt que l'inverse. Cela peut se vérifier en examinant les indices hydrologiques, tels que l'indice Palmer de gravité de sécheresse qui mesure à la fois les sécheresses et les précipitations extrêmes.

CONT

De nombreux indices de sécheresse ont été élaborés pour tenter de combiner les divers paramètres influant sur les sécheresses en un chiffre unique. À titre d'exemple, citons l'indice de précipitation cumulative, fondé sur un paramètre unique, celui des précipitations, et l'indice Palmer de gravité de sécheresse, plus complexe, basé sur une analyse en profondeur du bilan des eaux superficielles et une comparaison entre les valeurs réelles et les valeurs possibles compte tenu du climat.

OBS

On écrirait mieux «sècheresse».

OBS

sècheresse : Cette graphie, puisée des Rectifications de l'orthographe recommandées par le Conseil supérieur de la langue française, est attestée dans le Petit Robert (2006).

English

Subject field(s)
  • Soil Science
  • Drainage and Irrigation (Agric.)
CONT

... the soil condition, at the time set for the keyline cultivation of some areas, was very wet, and in the new areas, soil asphyxiation was evident.... Rain persisted and kept all the soil overwet right through to and past the middle of winter. Under these conditions, air which is so obviously essential, is excluded by excess water. The desirable balance of moisture, warmth and air in the soil had been destroyed.

CONT

Vegetative deaths caused by leachate generally are due to waterlogging and consequent soil anaerobism - not leachate toxicity.

CONT

Description of Planting Conditions. Soil characteristics, potentially related to plant failure are assessed including soil texture, compaction, anaerobism (oxygen depletion), waterlogging, presence of deleterious materials and stone content ...

Key term(s)
  • asphyxiation of soil

French

Domaine(s)
  • Science du sol
  • Drainage et irrigation (Agriculture)
DEF

État résultant d'un excès d'eau, caractérisé par une diminution de la proportion de l'oxygène disponible dans les pores du sol aboutissant à une situation pathologique des végétaux cultivés et au développement d'une flore microbienne anaérobie.

CONT

La forêt de Touffou est en effet un site humide, ce qui a posé et pose encore des problèmes au niveau de la gestion forestière. Cette humidité constante provoque une asphyxie du sol qui limite ainsi le développement des arbres.

Spanish

Campo(s) temático(s)

DEF

Estado de imbibición de agua que provoca una drástica disminución del oxígeno disponible y la aparición de una flora microbiana anaerobia.
