Abstract: The fluctuation of stationary waves caused by zonal mean flow changes is investigated using a barotropic model and GCM simulated upper-level data. The EOF analysis of monthly mean ? fluctuations during winter shows that a ...

Abstract: Long-term variations of global-mean air temperature at the surface are investigated using data from a GFDL coupled ocean-atmosphere model 139-year simulation and the observed datasets of surface air temperature over the ...

Abstract: nfluences of convective momentum transport (CMT) on tropical waves are analytically studied with an idealized model, which captures the first-order baroclinic structure in the vertical. The CMT has significant influence ...

Abstract: This paper provides a description of the variability of global atmospheric angular momentum (GAM) and its relationship with principal modes of three-dimensional atmospheric circulation anomalies. The data used are 5-day ...

Abstract: A series of linear and nonlinear barotropic models are used to interpret the extratropical response to El Niflo equatorial surface temperatures as simulated by an atmospheric general circulation model (GCM). The divergence, ...

Abstract: The predictability of intraseasonal variation in the tropics is assessed in the present study by using various statistical and dynamical models with rigorous and fair measurements. For a fair comparison, the real-time ...

Abstract: The upper tropospheric circulation during northern summer produced by a general circulation model (GCM) is studied using linear and nonlinear barotropic models and by analysing a streamfunction budget. The model experiments ...

Abstract: Principal modes of low-frequency atmospheric variability and the influence of sea surface temperature anomalies on such modes are investigated by examining the output from two general circulation model experiments. In the ...

Abstract: A simple model of interannual SST oscillation is developed using the two wave components of Kelvin and lowest symmetric Rossby waves. The model dynamics is similar to that of A. C. Hirst except the wind stress is simply ...

Abstract: The recharge oscillator paradigm for ENSO is further investigated by using a simple coupled model, which externally includes the equatorial wave dynamics represented by the Kelvin and gravest symmetric Rossby waves. To ...
