Abstract

Detecting abnormal climate events across temporal and spatial scales is crucial to the understanding of local and regional climate trends. Existing methods often depend on prior knowledge about the timing, location, or duration of such events, limiting their versatility. This study introduces ClimBurst, an approach to detect climate bursts (unusually high or low values of climate variables) without prior assumptions about their temporal duration. ClimBurst offers the ability to: (a) identify climate bursts of any duration within the time series of single locations, (b) link climate bursts across neighboring locations, and (c) analyze the spatio‐temporal propagation of these anomalies. Applying ClimBurst to sea surface temperature data from the Mediterranean Sea (1960–2021) shows some detected hot bursts and anomalies coincide in time with known severe marine heatwaves. ClimBurst also shows how detected hot (cold) bursts are spatio‐temporally connected and this connected bursts have increased (decreased) in duration, intensity, spatial extent and frequency historically.

ClimBurst：一种探测时空气候异常的新方法

探测跨时空尺度的异常气候事件对了解局地和区域气候趋势至关重要。现有的方法通常依赖于对这些事件的时间、位置或持续时间的先验知识，限制了它们的通用性。本研究介绍了ClimBurst，这是一种检测气候爆发（气候变量值异常高或低）的方法，无需事先假设其时间持续时间。ClimBurst提供了以下能力：(a)在单个地点的时间序列中识别任何持续时间的气候爆发，(b)将相邻地点的气候爆发联系起来，以及(c)分析这些异常的时空传播。将ClimBurst应用于地中海（1960-2021）的海面温度数据显示，一些探测到的热流和异常与已知的严重海洋热浪在时间上是一致的。ClimBurst还显示了检测到的热（冷）爆发是如何在时空上相互关联的，并且这种关联的爆发在持续时间、强度、空间范围和频率上都有增加（减少）的历史。
