“…ARs are essential to the global hydrological cycle and are often linked to societally impactful weather and climate extremes (Newell et al., 1992; Zhu & Newell, 1994). Due to their crucial role in water resource availability (Dettinger, 2013; Dettinger et al., 2011; Gorodetskaya et al., 2014) and their potential to produce heavy precipitation and flooding (Lavers et al., 2011, 2014; Neiman et al., 2008, 2013; Ralph et al., 2006; Waliser & Guan, 2017), numerous studies have investigated aspects of AR activity over the past two decades, including landfall activity (Hu et al., 2017; Rutz et al., 2014), connections to modes of climate variability (Gershunov et al., 2017; Guan & Waliser, 2015; Kim et al., 2017; Mundhenk et al., 2016; Payne & Magnusdottir, 2014; Zhou et al., 2021), subseasonal‐to‐seasonal prediction (DeFlorio, Waliser, Guan, Lavers, et al., 2018; DeFlorio, Waliser, Guan, Ralph, & Vitart, 2018; Lavers et al., 2014; Zhou & Kim, 2017;), and future projections (Gershunov et al., 2019; Lavers et al., 2013; Payne & Magnusdottir, 2015; Radić et al., 2015; Rhoades, Jones, Srivastava, et al., 2020; Shields & Kiehl, 2016b).…”
