Final answer:
The North Atlantic Subtropical High (NASH) has become more intense, with its westward ridge moving farther to the west, influencing weather patterns and marine life distribution through changes in ocean currents.
Step-by-step explanation:
A recent paper by Li et al. (2011) suggests that the North Atlantic Subtropical High (NASH) has become more intense, and its westward ridge has moved farther to the west. The change in the position and intensity of the NASH can significantly influence weather patterns, including precipitation and storm tracks. The shift in the NASH's western ridge is notable as it affects climate conditions over the adjacent landmasses, influencing everything from the distribution of marine life, such as phytoplankton and krill, due to changes in ocean currents and upwelling zones, to the increasing frequency and severity of extreme weather events, like hurricanes and droughts, as detailed in the provided contexts.
