Índice de lluvia impulsada por el viento

En Inglés, "wind-driven rain" se refiere a penetraciones de lluvia (impulsada por el viento) que ocurren en las fachadas, ventanas y puertas de edificios.
Para las mismas condiciones de lluvia y viento, la cantidad de agua que logra infiltrarse aumenta con la altura, razón por la cual se establece cierta altura de referencia (10 metros en este caso) en dicho índice o norma.

Wind-driven rain (WDR) or driving rain is rain that is given a horizontal velocity component by the wind and that falls obliquely.

The airfield index is defined as the quantity of WDR that would occur during one hour at a height at 10 m above ground level in the middle of an airfield, at the geographical location of the wall.
