Surface fluxes and tropical intraseasonal variability: a reassessment
Surface fluxes tropical intraseasonal variability
2009/12/2
The authors argue for the hypothesis that interactive feedbacks involving surface enthalpy fluxes, both turbulent and radiative, are important to the dynamics of tropical intraseasonal variability. ...
Statistics of locally coupled ocean and atmosphere intraseasonal anomalies in Reanalysis and AMIP data
locally coupled ocean atmosphere intraseasonal anomalies Reanalysis AMIP data
2009/11/12
We apply a simple dynamical rule to determine the dominant forcing direction in locally coupled ocean-atmosphere anomalies in the National Centers for Environmental Prediction/National Center for Atmo...
The Intraseasonal Oscillation in Eastern Pacific Sea Levels：How Is It Forced?
Intraseasonal Oscillation Eastern Pacific Sea Levels
2009/1/8
Daily sea level and surface winds at eastern Pacific shore locations and equatorial islands, together with gridded five-day averages of 850 mb winds, have been analyzed for the 1979–84 period to deter...
Intraseasonal Oscillations in Sea Level along the West Coast of the Americas
Intraseasonal Oscillations Americas Sea Level
2009/1/7
Hourly observations of coastal sea level at stations from Peru to British Columbia are analyzed for low-frequency content. A space-time contour plot of sea level, from four years of data during the 19...
Dynamics of Seasonal and Intraseasonal Variability in the Eastern Equatorial Pacific
Eastern Equatorial Pacific Seasonal Dynamics zonal wind stress Intraseasonal
2009/1/6
Time series measurements from surface moored buoys in the eastern equatorial Pacific are analyzed for the period 1983–86. The data, collected as part of the EPOCS and TROPIC HEAT programs, consist of ...
Structure of Intraseasonal Kelvin Waves in the Equatorial Pacific Ocean
Intraseasonal Kelvin Waves Equatorial Pacific Ocean
2008/12/18
Previous studies have shown that intraseasonal Kelvin waves are a prominent mode of variability in the eastern and central equatorial Pacific. These waves appear to be remotely forced by wind variatio...
Intraseasonal Variability in the Indo–Pacific Throughflow and the Regions Surrounding the Indonesian Seas
Intraseasonal Variability Indo–Pacific Throughflow Regions Surrounding Indonesian Seas
2008/7/16
Intraseasonal oscillations in sea level, sea surface temperature, and upper ocean flow field have recently been observed in various locations surrounding the Indonesian seas. While the observed oscill...
Dynamics of Remotely Forced Intraseasonal Oscillations off the Western Coast of South America
Remotely Forced Intraseasonal Western Coast South America
2008/7/8
Six years of sea level observations at six locations along the South American coast from Peru to Chile were analyzed at intraseasonal frequencies (periodicity 1–2 months). A high-resolution, low-frequ...
Variability of Intraseasonal Kelvin Waves in the Equatorial Pacific Ocean
Variability Intraseasonal Kelvin Waves Equatorial Pacific Ocean
2008/6/9
Previous observational work has demonstrated that the phase speed of oceanic equatorial Kelvin waves forced by the Madden–Julian oscillation (MJO) appears to vary substantially. Processes that are res...
Intraseasonal Variations in the Upper Equatorial Pacific Ocean prior to and during the 1997–98 El Niño
Upper Equatorial Pacific Ocean 1997–98 El Niñ o
2008/6/6
Time series data from the Tropical Atmosphere–Ocean (TAO) array of moored buoys and data from other sources are used to document the oceanic dynamical response to intraseasonal (periods centered near ...
Intraseasonal Variability in the South Equatorial Current of the East Indian Ocean
Intraseasonal Variability South Equatorial Current East Indian Ocean
2008/5/28
Satellite altimeter data reveal that the strongest intraseasonal variability in the southeast Indian Ocean occurs in the South Equatorial Current (SEC) during the second half of the year. The length s...
Evolution of the 2006–2007 El Nio:the role of intraseasonal to interannual time scale dynamics
Evolution 2006–2007 intraseasonal to interannual time scale dynamics
2010/1/27
We describe development of the 2006–2007 El Ni?o, which started late, ended early and was below average strength. Emphasis is on the interplay between large scale, low frequency (i.e., seasonal-to-int...
Remote ENSO forcing versus local air-sea interaction in QTCM: a sensitivity study to intraseasonal variability
Remote ENSO local air-sea interaction QTCM a sensitivity study
2010/1/25
The skill of a newly designed global atmospheric model of intermediate complexity - QTCM (for quasi-equilibrium tropical circulation model) in simulating the teleconnections is investigated. The role ...
