Ocean deoxygenation is becoming a major stressor for marine ecosystems due to anthropogenic climate change. Two major pathways through which climate change affects ocean oxygen are changes in wind fields and ch
Changes in the zonal gradients of sea surface temperature (SST) across the equatorial Pacific have major consequences for global climate. Therefore, accurate future projections of these tropical Pacific gradients are of paramount importance for climate m
Particle flux was related to rain, freshwater discharge, and phytoplankton blooms. The North Pacific warm water anomaly (known popularly as the Blob) reached coastal waters during the second year of deployment, resulting in more autumn rain and less snow than during the other 2years. The maximum...
dT/dt=Rsw−Rlw+Hs+LE+vdh/dy 其中右边项分别是太阳短波,地球长波,显热(sensible heat flux),潜热(latent heat flux)和水平平流。 我们将两边同时减去气候态,就可以得到在各个时刻的偏离量(anomaly)。再将两边同时乘上同一时刻的温度偏离(temperature anomaly),就可以达到一个关于T的covariance的等式。 CaTb′...
To investigate the changes in SSUC circulation and upwelling, the regional-scale sensitivity experiments are carried out with forcings (air-sea fluxes, lateral ocean boundary conditions, and initial conditions) perturbed by CC signals derived from CMIP5. Results are compared with a reference simulatio...
Coupled to the ocean, there is a well-mixed atmospheric box which only solves for atmospheric pCO2, and the air-sea flux of carbon is parametrized following Wanninkhof [1992]. The model resolution is chosen such that a large set of perturbation experiments can be run for centuries while ...
ocean ridge (MOR) settings have been extensively studied3,4, the reliable estimations of global elemental fluxes from hydrothermal vents, including those in low-temperature systems (<150 °C), remains difficult because of uncertainties in water volume flux and hydrothermal fluid chemistry3,6,8. ...
Most extinctions are associated with global warming and proximal killers such as marine anoxia (including the Early/Middle Cambrian, the Late Ordovician, the intra-Silurian, intra-Devonian, end-Permian, and Early Jurassic crises). Many, but not all of these are accompanied by large negative ...
Mesoscale eddies are present everywhere in the ocean and partly determine the mean state of the circulation and ecosystem. The current feedback on the surface wind stress modulates the air-sea transfer of momentum by providing a sink of mesoscale eddy energy as an atmospheric source. Using nine ...
cross-checked against the geometry of velocity streamlines around the sea-level anomaly (SLA) maximum. Several Argo floats followed the westward-migrating AC through summer until the eddy disintegrated on encountering the Izu Ridge in late September (Fig. 1b). The floats provide more than 3,000...
