Abstract: The persistence of multiple jets is investigated with a quasigeostrophic, two-layer, ?-plane channel model. Linearly unstable normal modes are found to be capable of qualitatively describing the eddy fluxes of the nonlinear ...

Abstract: n increase in the poleward heat or energy transport is often ascribed to a strengthening of the equator-to-pole gradient in temperature or in the top-of-the-atmosphere (TOA) net radiation. While this attribution conforms ...

Abstract: sing an initial-value approach with an idealized general circulation model, the mechanisms by which the Madden?Julian oscillation (MJO) influences the Arctic surface air temperature (SAT) are investigated. Model calculations ...

Abstract: sing lagged composites and projections with the thermodynamic energy equation, in this study the mechanisms that drive the boreal winter Arctic surface air temperature (SAT) change associated with the Madden?Julian oscillation ...

Abstract: ropical Atlantic sea surface temperature changes have recently been linked to circulation anomalies around Antarctica during austral winter. Warming in the tropical Atlantic associated with the Atlantic multidecadal ...

Abstract: AbstractInterannual variation of seasonal-mean tropical convection over the Indo-Pacific region is primarily controlled by El Niño?Southern Oscillation (ENSO). For example, during El Niño winters, seasonal-mean convection ...

Abstract: he Madden?Julian oscillation (MJO), the dominant mode of tropical intraseasonal variability, influences weather and climate in the extratropics through atmospheric teleconnection. In this study, two simulations using the ...
