“…A similar deglacial temperature pattern was previously reported in the Cape Basin records (CBR cores, Figure 5D) (Peeters et al, 2004). Deglaciations are associated with an increase in the Agulhas Leakage, which is the outflow of warm and saline waters from the Agulhas Current in the South Atlantic (Nirmal et al, 2023;Peeters et al, 2004) (Figure 5E). The intensity of the Agulhas Leakage strongly depends on the position of the southern hemisphere mid-latitude westerlies (Biastoch et al, 2009).…”

“…Variations of the westerly wind belt and AFS are hypothesized to modulate Agulhas Leakage (AL) intensity [12]. Proxy records associate northward shifts of the AFS with intervals of reduced AL [13][14][15], and intensification of winter rainfall over SA on millennial timescales [16,17]. However, there is debate over how the westerlies and AL influence SA rainfall in the modern [18][19][20].…”

“…Furthermore, several characteristics, such as volume and velocity of agulhas current, fluctuations of hydrographic fronts and wind patterns in the Southern Hemisphere, have been identified that are associated with the change in the intensity of Agulhas Leakage. The STF is a zone of active interaction between atmospheric and ocean circulation, which heavily influences the interocean transfer (Nirmal et al, 2023). A northward position of the front serving as a blockage, impeding the transfer of heat and salt through AL (Bard & Rickaby, 2009).…”

“…The position of the STF and, therefore, the variability of leakage, is influenced by alterations in the Earth's orbital parameters, the position of westerlies, and the amount of solar insolation. The increased leakage during the interglacials strengthens the AMOC and plays an important role in global heat transport (Bard & Rickaby, 2009;Caley et al, 2012;Nirmal et al, 2023). Agulhas Leakage, has garnered increasing attention due to its profound influence on ocean circulation, heat transport and climate.…”
