1. Introduction To date, two largely separate lines of research pertinent to extratropical air–sea interaction have convincingly demonstrated that midlatitude storm tracks are strongly influenced by their thermal interactions with sea surface temperature (SST) over western boundary current (WBC) regions, and that the energetics and stability of the WBCs themselves are controlled by their mechanical interaction with the atmosphere via surface currents. The former line of research posits that

Nakamura 2005 , 2010 ; Miyamoto et al. 2021a ), the diminished land–sea thermal contrast and associated atmosphere–ocean–land feedback system are consistent with the westward shift of the Mascarene high observed in austral winter.

, leading to the offshore deflection of SC at 10°N along the northern shoulder of the GW. This scale-to-scale interaction between the ocean and the atmosphere on a relatively narrow scale is important for the modeled GW position and the SC separation in comparison to the observations. The finescale SST gradients also produce anomalous Ekman upwelling (downwelling) in the northern edge of the GW (CF), which exerts an additional forcing of the GW and CF at the southerly position. If these SST effects are

The highest-resolution simulation used here, with 0.25° resolution in the atmosphere and nominal 0.1° in the ocean, is described in full in Small et al. (2014) . It was run for 100 years under “present-day” (year 2000

1. Introduction It has been recognized for decades that for basin-scale air–sea interactions in midlatitudes, coupling between the atmosphere and ocean is largely linear and passive in nature ( Barsugli and Battisti 1998 ; Frankignoul 1985 ). In this passive air–sea coupling, the ocean responds to white-noise atmospheric internal variability through turbulent air–sea heat fluxes, giving rise to a red-noise response in sea surface temperature (SST; Frankignoul and Hasselmann 1977 ; Hasselmann

1. Introduction Large-scale extratropical ocean–atmosphere interaction has long been recognized as dominated by atmospheric forcing of the ocean ( Davis 1976 ; Frankignoul and Hasselmann 1977 ; Frankignoul 1985 ). However, ocean–atmosphere coupling varies considerably across the midlatitude ocean basins, with oceanic processes likely to be more important to sea surface temperature (SST) variability in the vicinity of the western boundary currents (WBCs) and their associated SST fronts ( Qiu

a slab ocean mixed layer model, as elegantly demonstrated by Barsugli and Battisti (1998) . The latter involves complex interactions between atmospheric storm tracks and SST fronts along intense ocean western boundary current (WBCs) ( Nakamura et al. 2004 , 2008 ), which are less understood. Many recent studies on midlatitude atmosphere–ocean interactions focus on the latter mechanism. Special attention has been paid to the Kuroshio Extension region (KER) in the North Pacific and the Gulf
