Les couches tram\u00e9es des pr\u00e9cipitations annuelles que propose l\u2019Atlas environnemental de l\u2019Am\u00e9rique du Nord repr\u00e9sentent des variables climatologiques cl\u00e9s, notamment les pr\u00e9cipitations annuelles totales, les pr\u00e9cipitations du mois le plus humide et les pr\u00e9cipitations du mois le plus sec. Ces ensembles de donn\u00e9es sont bas\u00e9s sur les normales climatologiques pour la p\u00e9riode de r\u00e9f\u00e9rence de 1981 \u00e0 2010.<\/p>\n

Ensemble, ces couches de pr\u00e9cipitations annuelles illustrent \u00e0 la fois la r\u00e9partition spatiale des pr\u00e9cipitations en Am\u00e9rique du Nord et leur variabilit\u00e9 saisonni\u00e8re tout au long de l\u2019ann\u00e9e. Elles fournissent des renseignements d\u00e9taill\u00e9s sur les quantit\u00e9s annuelles totales ainsi que sur les valeurs extr\u00eames des mois les plus humides et les plus secs et appuient un large \u00e9ventail d\u2019analyses \u00e9cologiques, environnementales et climatiques. Elles comprennent les conditions climatologiques de r\u00e9f\u00e9rence essentielles \u00e0 toutes sortes d\u2019activit\u00e9s\u00a0: la mod\u00e9lisation de la r\u00e9partition des esp\u00e8ces, l\u2019interpr\u00e9tation de la couverture terrestre, l\u2019\u00e9valuation des incidences sur le climat, l\u2019agriculture et la foresterie, l\u2019\u00e9valuation des ressources en eau et la mod\u00e9lisation hydrologique.<\/p>\n

Les couches de pr\u00e9cipitations pour l\u2019Am\u00e9rique du Nord se fondent sur les jeux de variables bioclimatiques CHELSA\u00a0v2.1 et de donn\u00e9es CHELSA-climatologies\u00a0v2.1, produits climatiques mondiaux \u00e0 haute r\u00e9solution \u00e9labor\u00e9s dans le cadre du projet Climatologies at High Resolution for the Earth's Land Surface Areas<\/em> (CHELSA, Climatologies \u00e0 haute r\u00e9solution pour les surfaces terrestres de la Terre), qui se d\u00e9roule \u00e0 l\u2019Institut f\u00e9d\u00e9ral de recherches sur la for\u00eat, la neige et le paysage WSL.<\/p>\n","protected":false},"excerpt":{"rendered":"
