Simulating low frequency changes in atmospheric CO2 during the last 740 000 years
low frequency frequency changes atmospheric CO2
2008/11/10
Atmospheric CO2 measured in Antarctic ice cores shows a natural variability of 80 to 100 ppmv during the last four glacial cycles and variations of approximately 60 ppmv in the two cycles between 410 ...
Low-frequency oscillations of the Atlantic Ocean meridional overturning circulation in a coupled climate model
Low-frequency oscillations Atlantic Ocean meridional overturning circulation climate model
2008/11/4
Using a 3-dimensional climate model of intermediate complexity we show that the overturning circulation of the Atlantic Ocean can vary at multicentennial-to-millennial timescales for modern boundary c...
Statistical correlation of spectral broadening in VLF transmitter signal and low-frequency ionospheric turbulence from observation on DEMETER satellite
Statistical correlation spectral broadening VLF transmitter signal DEMETER satellite
2009/12/31
In our earlier papers we have found the effect of VLF transmitter signal depression over epicenters of the large earthquakes from observation on the French DEMETER satellite that can be considered as ...
Spectral Description of Low-Frequency Oceanic Variability
Spectral Description Low-Frequency Oceanic Variability
2008/7/30
A synthesis is made of simple dynamics with a wide variety of observations to produce a zero-order approximate analytical spectral description of low-frequency oceanic variability in the Northern Hemi...
Rossby Wave–Coastal Kelvin Wave Interaction in the Extratropics. Part I: Low-Frequency Adjustment in a Closed Basin
Rossby Wave–Coastal Kelvin Wave Interaction Low-Frequency Adjustment Closed Basin
2008/7/22
The interaction of open and coastal oceans in a midlatitude ocean basin is investigated in light of Rossby and coastal Kelvin waves. The basinwide pressure adjustment to an initial Rossby wave packet ...
Seasonal and Low-Frequency Variability of the Meridional Heat Flux at 36°N in the North Atlantic
Seasonal Low-Frequency Meridional Heat Flux North Atlantic
2008/6/30
Historical hydrographic sections are used to investigate the seasonal and interannual variability in the meridional heat flux at 36°N in the North Atlantic. The data consist of ten transatlantic secti...
Low-Frequency Variability in the Wind-Driven Circulation
Low-Frequency Variability Wind-Driven Circulation
2008/6/30
The origins of low-frequency variability in a simple homogenous ocean model, forced by a double gyre Ekman suction, are examined numerically. It is found that irregular, large amplitude vacillations i...
Low-Frequency Pycnocline Depth Variability at Ocean Weather Station P in the Northeast Pacific
Low-Frequency Pycnocline Depth Variability Ocean Weather Station Northeast Pacific
2008/6/23
Low-frequency variability of the depth of the main pycnocline at Ocean Weather Station P and over the northeast Pacific is examined in terms of the one-dimensional response to local Ekman pumping acco...
Long Rossby Wave Basin-Crossing Time and the Resonance of Low-Frequency Basin Modes
Long Rossby Wave Basin-Crossing Time Low-Frequency Basin Modes
2008/6/13
The ability of long-wave low-frequency basin modes to be resonantly excited depends on the efficiency with which energy fluxed onto the western boundary can be transmitted back to the eastern boundary...
Multiple Equilibria and Low-Frequency Variability of the Wind-Driven Ocean Circulation
Multiple Equilibria Low-Frequency Variability Wind-Driven Ocean Circulation
2008/6/11
The link between low-frequency time-dependent variability and the existence of multiple unstable steady-state solutions in a reduced gravity quasigeostrophic ocean model for the midlatitude wind-drive...
Low-Frequency Current Observations in the Korea/Tsushima Strait
Low-Frequency Current Korea/Tsushima Strait
2008/6/9
High resolution, continuous current measurements made in the Korea/Tsushima Strait between May 1999 and March 2000 are used to examine current variations having time periods longer than 2 days. Twelve...
Spontaneous Generation of Low-Frequency Modes of Variability in the Wind-Driven Ocean Circulation
Spontaneous Generation Low-Frequency Modes Wind-Driven Ocean Circulation
2008/6/9
In idealized models that aim to understand the temporal variability of the wind-driven ocean circulation, low-frequency instabilities associated with so-called oscillatory gyre modes have been found. ...
