L'indice d'hydratation superficielle peut être normalisé, brut ou intégré temporellement. On peut citer comme exemples : l'indice normalisé d'hydratation de la végétation (en anglo-américain : Leaf Water Content Index, abréviation : L.W.C.I.), l'indice normalisé d'hydratation du sol (en anglo-américain Soil Water Content Index, abréviation : S.W.C.I.), lesquels prennent en compte à la fois une bande spectrale du proche infrarouge et une bande spectrale significative du moyen infrarouge.  2, record 1, French, - indice%20d%27hydratation%20superficielle

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 2, English, - Palmer%20drought%20severity%20index

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.  9, record 2, English, - Palmer%20drought%20severity%20index

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.  10, record 2, English, - Palmer%20drought%20severity%20index

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.  5, record 2, French, - indice%20de%20s%C3%A9v%C3%A9rit%C3%A9%20de%20s%C3%A9cheresse%20de%20Palmer

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.  6, record 2, French, - indice%20de%20s%C3%A9v%C3%A9rit%C3%A9%20de%20s%C3%A9cheresse%20de%20Palmer

L'évapotranspiration et les flux turbulents de chaleur sensible et latente sont d'abord évalués au niveau de la station micro-météorologique de référence. Un indice de l'humidité disponible dans le sol est ensuite calculé à partir du rapport du flux de chaleur latente et du bilan énergétique de surface. Cet indice est sensé être représentatif de toute la Belgique, le principal facteur gouvernant l'évapotranspiration étant, dans les climats tempérés, le rayonnement net modulé par la présence ou l'absence de nuages.  1, record 3, French, - indice%20de%20l%27humidit%C3%A9%20disponible
