Annual Cycle and ENSO in a Coupled Ocean–Atmosphere General Circulation Model
Results from multiyear integrations of a coupled ocean–atmosphere general circulation model are described. The atmospheric component is a rhomboidal 15, 18-level version of the Center for Ocean–Land–Atmosphere Studies atmospheric general circulation model. The oceanic component is the Geophysical Fluid Dynamics Laboratory ocean model with a horizontal domain extending from 708S to 658N. The oce...
متن کاملCoupling between annual and ENSO timescales in the malaria-climate association in Colombia.
We present evidence that the El Niño phenomenon intensifies the annual cycle of malaria cases for Plasmodium vivax and Plasmodium falciparum in endemic areas of Colombia as a consequence of concomitant anomalies in the normal annual cycle of temperature and precipitation. We used simultaneous analyses of both variables at both timescales, as well as correlation and power spectral analyses of de...
متن کاملENSO theory
Beginning from the hypothesis by Bjerknes [1969] that oceanatmosphere interaction was essential to the E1 Nifio-Southern Oscillation (ENSO) phenomenon, the Tropical Ocean-Global Atmosphere (TOGA) decade has not only confirmed this but has supplied detailed theory for mechanisms setting the underlying period and possible mechanisms responsible for the irregularity of ENSO. Essentials of the theo...
متن کاملENSO Time Scales
The North Paci c thermocline (250m to 400m) is studied using XBT observations acquired during the 1970s and 1980s. Interannual variations (3-5 year time scales) in thermocline temperature, with O(0.1 C) amplitude at 400m, are found to exhibit westward propagation throughout the extra-tropical North Paci c up to 45N. Southwards of 30N, the features propagate intact across the basin from the east...
متن کاملQuantifying Persistence in ENSO
The seasonal dependence of predictability in ENSO manifests itself in the so-called spring barrier found in the cyclostationary lag autocorrelations, or persistence. This work examines the statistics of persistence, with particular focus on the phase-of-year-dependent pattern found in ENSO data, the barrier. Simple time series of one sine wave produce a barrier if the frequency is a biennial cy...
