RISAntarctic Bottom Water Variability in a Coupled Climate Model
Publisher: American Meteorological Society
Abstract: The natural variability of the Weddell Sea variety of Antarctic Bottom Water (AABW) is examined in a long-term integration of a coupled climate model. Examination of passive tracer concentrations suggests that the model ...
Antarctic Intermediate Water Circulation and Variability in a Coupled Climate Model
Publisher: American Meteorological Society
Abstract: The variability of Antarctic Intermediate Water (AAIW) in a long-term natural integration of a coupled climate model is examined. The mean state of the climate model includes a realistic representation of AAIW, which appears ...
Assessing the Impact of Model Biases on the Projected Increase in Frequency of Extreme Positive Indian Ocean Dipole Events
Publisher: American Meteorological Society
Abstract: AbstractFor many generations, models simulate an Indian Ocean dipole (IOD) that is overly large in amplitude. The possible impact of this systematic bias on climate projections, including a projected frequency increase in ...
Multidecadal ENSO Amplitude Variability in a 1000-yr Simulation of a Coupled Global Climate Model: Implications for Observed ENSO Variability
Publisher: American Meteorological Society
Abstract: he amplitude of the El Niño?Southern Oscillation (ENSO) can vary naturally over multidecadal time scales and can be influenced by climate change. However, determining the mechanism for this variation is difficult because ...
Interannual Tasmanian Rainfall Variability Associated with Large-Scale Climate Modes
Publisher: American Meteorological Society
Abstract: Interannual rainfall variability over Tasmania is examined using observations and reanalysis data. Tasmanian rainfall is dominated by an east?west gradient of mean rainfall and variability. The Pacific?South American mode ...
Genesis of Indian Ocean Mixed Layer Temperature Anomalies: A Heat Budget Analysis
Publisher: American Meteorological Society
Abstract: The genesis of mixed layer temperature anomalies across the Indian Ocean are analyzed in terms of the underlying heat budget components. Observational data, for which a seasonal budget can be computed, and a climate model ...
Impact of the El Niño–Southern Oscillation, Indian Ocean Dipole, and Southern Annular Mode on Daily to Subdaily Rainfall Characteristics in East Australia
Publisher: American Meteorological Society
Abstract: he relationship between seasonal aggregate rainfall and large-scale climate modes, particularly the El Niño?Southern Oscillation (ENSO), has been the subject of a significant and ongoing research effort. However, relatively ...
Interannual Rainfall Extremes over Southwest Western Australia Linked to Indian Ocean Climate Variability
Publisher: American Meteorological Society
Abstract: Interannual rainfall extremes over southwest Western Australia (SWWA) are examined using observations, reanalysis data, and a long-term natural integration of the global coupled climate system. The authors reveal a ...
Circumpolar Deep Water Circulation and Variability in a Coupled Climate Model
Publisher: American Meteorological Society
Abstract: The natural variability of Circumpolar Deep Water (CDW) is analyzed using a long-term integration of a coupled climate model. The variability is decomposed using a standard EOF analysis into three separate modes accounting ...
Indo-Pacific Climate Interactions in the Absence of an Indonesian Throughflow
Publisher: American Meteorological Society
Abstract: he Pacific and Indian Oceans are connected by an oceanic passage called the Indonesian Throughflow (ITF). In this setting, modes of climate variability over the two oceanic basins interact. El Niño?Southern Oscillation ...
