The North Pacific Gyre Oscillation (NPGO) is a climate pattern that emerges as the 2nd dominant mode of sea surface height variability (2nd EOF SSH) in the Northeast Pacific. The NPGO is significantly correlated with previously unexplained fluctuations of salinity , nutrients and chlorophyll-a measured in long-term observations in the ...

2018年3月15日 · Like the PDO, the North Pacific Gyre Oscillation (NPGO), representing the second leading mode of sea surface height (SSH) anomalies in the northeast Pacific, is a basin-scale feature and captures prominent low-frequency changes in the Pacific physical and biological fields including temperature, salinity, sea level, nutrients, chlorophyll-a ...

2008年4月30日 · We define a new pattern of climate change, the North Pacific Gyre Oscillation (NPGO) and show that its variability is significantly correlated with previously unexplained fluctuations of salinity, nutrients and chlorophyll.

The Northern Pacific Gyre Oscillation (NPGO) is a newer recognized climate index used to describe and pair changes in salinity and nutrients, not previously well correlated to the Pacific Decadal Oscillation (PDO).

The time-series webpages associaed with the GCOS Surfac Pressure are being taken down. They are being replaced with in the location PSL Monthly Time-series.

The North Pacific Gyre Oscillation (NPGO) is a climate pattern that emerges as the 2nd dominant mode of sea surface height variability (2nd EOF SSH) in the Northeast Pacific.

The North Pacific Gyre Oscillation (NPGO) is a climate pattern. It is used as an index to measure changes in ocean currents and circulation patterns and explains key physical-biological variables. It is significantly correlated with previously unexplained fluctuations of salinity, nutrients and chlorophyll-a measured in long-term observations ...

2015年8月7日 · The decadal variability of the North Pacific gyre oscillation (NPGO) over the 20 th century is examined from a long-term integration of the Simple Ocean Data Assimilation (SODA) reanalysis. The NPGO is reflected by the second dominant pattern of sea surface height (SSH) variability in SODA, with a north-south dipole structure over the northeast ...

NPGO 是东北太平洋海表面高度异常(SSHA)经验正交函数(EOF)分解的第二模态,空间结资料中得到(Qiu and Chen,2010),而且可在海洋模式的回报试验得到证实(Chhak et al.,2009),这一结果还得到了IPCC AR4海气耦合模式的验证(Furtado et al.,2011)。 以上研究表明,NPGO模态是近年来发现的重要的太平洋海表温度异常的年代际变化。 然而,NPGO是否仅表现在海洋表层温度异常上,是否也存在于海洋上层?该海温异常的空间结构特点如何?时间尺度又如何?此外,造成NPGO的原因是 …

The North Pacific Gyre Oscillation (NPGO) is a climate pattern introduced by Di Lorenzo et al. (2008) and further reported by Tranchant et al. (2019) in the CMEMS Ocean State Report #3. The NPGO is defined as the second dominant mode of variability of Sea Surface Height (SSH) anomaly and SST anomaly in the Northeast Pacific (25°– 62°N, 180 ...
