Interannual variability of phytoplankton abundances in the North Atlantic
A framework is developed for examining spatial patterns of interannual variability in springtime chlorophyll concentrations as a response to physical changes. A simpli"ed, two-layer bio-physical model reveals regional responses to interannual variability of convective mixing. Vertical mixing can promote productivity in the surface waters through enhanced nutrient supply, but also can retard pro...
متن کاملInterannual variability in the North Atlantic Ocean carbon sink.
The North Atlantic is believed to represent the largest ocean sink for atmospheric carbon dioxide in the Northern Hemisphere, yet little is known about its temporal variability. We report an 18-year time series of upper-ocean inorganic carbon observations from the northwestern subtropical North Atlantic near Bermuda that indicates substantial variability in this sink. We deduce that the carbon ...
متن کاملInterannual Variability of High-Wind Occurrence over the North Atlantic*
Interannual variability of high-wind occurrence over the North Atlantic is investigated based on observations from the satellite-borne Special Sensor Microwave Imager (SSM/I). Despite no wind direction being included, SSM/I data capture major features of high-wind frequency (HWF) quite well. Climatology maps show that HWF is highest in winter and is close to zero in summer. Remarkable interannu...
متن کاملInterannual variability of primary production and dissolved organic nitrogen storage in the North Pacific Subtropical Gyre
[1] The upper ocean primary production measurements from the Hawaii Ocean Time series (HOT) at Station ALOHA in the North Pacific Subtropical Gyre showed substantial variability over the last two decades. The annual average primary production varied within a limited range over 1991–1998, significantly increased in 1999–2000 and then gradually decreased afterwards. This variability was investiga...
متن کاملInterannual variability of winter precipitation in the European Alps: relations with the North Atlantic Oscillation
The European Alps rely on winter precipitation for various needs in terms of hydropower and other water uses. Major European rivers originate from the Alps and depend on winter precipitation and the consequent spring snow melt for their summer base flows. Understanding the fluctuations in winter rainfall in this region is crucially important to the study of changes in hydrologic regime in river...
