WebOnce the coastal ocean is anomalously warmed/cooled through oceanic processes, it starts heating/cooling the overlying atmosphere and induces baroclinic responses over the ocean with negative/positive geopotential height anomalies in the lower troposphere (Xue et al., 2024). This further strengthens the alongshore wind anomalies in turn. Geopotential height or geopotential altitude is a vertical coordinate referenced to Earth's mean sea level, an adjustment to geometric height (altitude above mean sea level) that accounts for the variation of gravity with latitude and altitude. Thus, it can be considered a "gravity-adjusted height". It is the altitude all aircraft's barometric altimeters are calibrated to.
