太阳风变量的时间序列具有突发性。太阳风参数时间序列中的爆发或漂移与太阳风等离子体中的各种瞬变结构有关,往往是地球磁层空间气象活动增加的驱动因素。我们通过设置时间序列的阈值并确定超过该阈值的频率和时间来定义突发。这使我们能够研究爆发参数的统计分布和标度特性如何在太阳活动周期23和24周内变化。我们发现爆发持续时间和积分爆发大小的分布在太阳活动周期内以及在连续太阳活动周期的等值位相之间不同。然而,爆发大小和持续时间之间存在单一的幂函数标度关系,其联合面积-持续时间标度指数α与太阳周期无关。这在可能发生的太阳风爆发的可能大小和持续时间之间提供了太阳周期不变的约束。
Time series of solar wind variables are bursty in nature. Bursts, or excursions, in the time series of solar wind parameters are associated with various transient structures in the solar wind plasma and are often the drivers of increased space weather activity in Earth's magnetosphere. We define bursts by setting a threshold value of the time series and identifying how often, and for how long, it is exceeded. This allows us to study how the statistical distributions and scaling properties of burst parameters vary over solar cycles 23 and 24. We find that the distributions of burst duration and integrated burst size vary over the solar cycle and between the equivalent phases of consecutive cycles. However, there exists a single power law scaling relation between burst size and duration, with a joint area‐duration scaling exponentαthat is independent of the solar cycle. This provides a solar cycle invariant constraint between possible sizes and durations of solar wind bursts that can occur.
