Relative influence of oceanic and terrestrial pressure systems in driving upwelling‐favorable winds
Open accessAbstract
We use the 20th Century Reanalysis database to assess the influence of oceanic and terrestrial atmospheric pressure systems on winter and summer upwelling‐favorable winds in Eastern Boundary Upwelling Systems. The analysis provides baseline information regarding the roles of continental thermal low (CTL) and oceanic high (OH) pressure systems in driving seasonal upwelling modes, which have high biological relevance. We show that variability in upwelling‐favorable winds is dominated by OH, particularly in winter, and only weakly influenced by CTL, except at annual time scales. This is most pronounced in the California system given that the North Pacific High dominates wind variability. In contrast, CTL and OH equally influence Benguela upwelling‐favorable winds during summer. This work underscores the need to understand how OH systems are likely to respond to climate change and how this might impact coastal winds that drive upwelling and productivity in these ecosystems.

Upwelling winds in the California Current occur in distinct winter and summer seasonal modes, each with unique atmospheric drivers and differential impacts on biological processes, as documented in rockfish growth and seabird reproductive success.
“Related to the concept of spring transition, upwelling winds in the California Current occur in distinct winter and summer seasonal Bmodes,^each with unique atmospheric drivers [10] and differential impacts on biological processes, as documented in rockfish (Sebastes spp.) growth and seabird reproductive success [85].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
