“…Many previous studies have demonstrated the usefulness of averaging around cyclone centers to examine midlatitude behavior, including aerosol variability (Field et al, 2011;Field and Wood, 2007;Naud et al, 2016Naud et al, , 2017Catto, 2016;Grandey et al, 2013). A variety of different techniques for locating cyclone centers and compositing around elements of cyclones exist in the literature, utilizing pressure fields , and flipped so they are poleward oriented (c).…”
