The stochastic modeling of extremes is important to many fields. Estimation of the incidence and severity of floods, large winds, large precipitations (rain, snow, or ice), and so on are essential to engineering when many structural designs rely on data-based methodologies for the estimation of design loads. Underestimation of probable extreme loads leads to catastrophic structural failure; recall the state of the transmission towers after the Ice Storms.

极值的随机建模在许多领域都具有重要意义。当许多结构设计依赖于基于数据的方法来估计设计荷载时，洪水、大风、大降水（雨、雪或冰）等的发生率和严重程度的估计对工程至关重要。 低估可能的极端载荷会导致灾难性的结构故障;回想冰风暴后输电塔的状态。
