对极端事件的反应：移动阈值模型
Reactions to extreme events: moving threshold model
摘要：
尽管采取了预防措施，以避免极端事件的有害影响，但我们经常遇到克服预防障碍的现象。这些障碍通常在这种极端事件发生后急剧增加，但在没有极端事件的情况下会稳步衰减。在本文中，我们考虑一个简单的模型，模仿的保护屏障的演变，研究系统的反应，极端事件的效率，以及它如何改变我们的看法的极端事件本身的序列。我们得到，通常的方法，打击极端事件介绍了一个周期性的发生，一般是效率低于使用一个恒定的障碍。另一方面，它表现出良好的适应缓慢的非平稳性的存在。
英文摘要：
In spite of precautions to avoid the harmful effects of extreme events, we experience recurrently phenomena that overcome the preventive barriers. These barriers usually increase drastically right after the occurrence of such extreme events, but steadily decay in their absence. In this paper we consider a simple model that mimics the evolution of the protection barriers to study the efficiency of the system's reaction to extreme events and how it changes our perception of the sequence of extreme events itself. We obtain that the usual method of fighting extreme events introduces a periodicity in their occurrence and is generally less efficient than the use of a constant barrier. On the other hand, it shows a good adaptation to the presence of slow non-stationarities.
