  rdf:value "The boundary between the troposphere and the stratosphere, usually characterized by an abrupt change of lapse rate. The change is in the direction of increased atmospheric stability from regions below to regions above the tropopause. Its height varies from 15 to 20 kilometers in the tropics to about 10 kilometers in polar regions. In polar regions in winter it is often difficult or impossible to determine just where the tropopause lies, since under some conditions there is no abrupt change in lapse rate at any height."@en, "Límite entre la troposfera y la estratosfera, caracterizado generalmente por un cambio abrupto en el gradiente térmico. Dicho cambio tiene lugar en la dirección de mayor estabilidad atmosférica, desde regiones que se encuentran por debajo de la tropopausa hasta regiones que se hallan sobre ella. Su altura varía de 15 a 20 km en los trópicos a aproximadamente 10 km en las regiones polares. En el invierno, en las regiones polares suele resultar difícil y hasta imposible determinar dónde se ubica la tropopausa, dado que en ciertas condiciones no se da ningún cambio abrupto en el gradiente térmico a ninguna altura."@es ;
