ENSO teleconnections in projections of future climate in ECHAM5/MPI-OM

Interdecadal Modulation of ENSO Teleconnections

The existence of quasi-decadal variability in the Pacific sector climate (e.g., Latif and Barnett 1994, 1996; Mantua et al. 1997; Minobe 1997) has important implications for long-range climate prediction in North America. The spatial manifestations in climate variables around the North Pacific sector associated with the North Pacific oscillation (NPO) are qualitatively similar to those of ENSO....

ENSO Evolution and Teleconnections in IPCC’s Twentieth-Century Climate Simulations: Realistic Representation?

This study focuses on the assessment of the spatiotemporal structure of ENSO variability and its winter climate teleconnections to North America in the Intergovernmental Panel on Climate Change’s (IPCC) Fourth Assessment Report (AR4) simulations of twentieth-century climate. The 1950–99 period simulations of six IPCC models are analyzed in an effort to benchmark models in the simulation of this...

ENSO and IOD teleconnections for African ecosystems: evidence of destructive interference between climate oscillations

Rainfall and vegetation across Africa are known to resonate with the coupled ocean-atmosphere phenomena of El Niño Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). However, the regional-scale implications of sea surface temperature variability for Africa’s photosyntheis have received little focused attention, particularly in the case of IOD. Furthermore, studies exploring the inte...

Mechanism study of the ENSO and southern high latitude climate teleconnections

[1] Evidence of El Niño-Southern Oscillation (ENSO) teleconnections in the southern high latitude climate has been identified, although the mechanisms that might lead to such far-reaching teleconnections remain unresolved. Here we propose one such mechanism-the regional mean meridional atmospheric circulation (the regional Ferrel Cell)-responsible for the covariability of the ENSO and Antarctic...
