[The] Thornthwaite moisture index [is] a method for monitoring the soil water budget for relatively large areas based on the pioneering work of C. W. Thornthwaite (1948) using the concept of potential evapotranspiration. The Palmer Drought Severity Index and the companion "crop moisture index," developed by W. C. Palmer, are modifications of the earlier Thornthwaite work.  4, record 2, English, - Thornthwaite%20moisture%20index

An index of the degree of water surplus over water need at any given station; it is calculated as humidity index = 100s/n, where s (the water surplus) is the sum of the monthly differences between precipitation and potential evapotranspiration for those months when the normal precipitation exceeds the latter, and where n (the water need) is the sum of monthly potential evapotranspiration for those months of surplus.  2, record 3, English, - humidity%20index

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 4, French, - indice%20de%20l%27humidit%C3%A9%20disponible
