RISEvaluation of Interior Circulation in a High-Resolution Global Ocean Model. Part I: Deep and Bottom Waters
Publisher: American Meteorological Society
Abstract: Global watermass ventilation pathways and time scales are investigated using an ?eddy permitting? (¼°) offline tracer model. Unlike previous Lagrangian trajectory studies, here an offline model based on a complete tracer ...
Coupled Ocean–Atmosphere–Ice Response to Variations in the Southern Annular Mode
Publisher: American Meteorological Society
Abstract: The coupled ocean?atmosphere?ice response to variations in the Southern Annular Mode (SAM) is examined in the National Center for Atmospheric Research (NCAR) Community Coupled Climate Model (version 2). The model shows ...
Coupled Ocean–Atmosphere Feedback in the Southern Annular Mode
Publisher: American Meteorological Society
Abstract: Previous studies have demonstrated that while the Southern Annular Mode (SAM) is an intrinsic feature of the atmosphere, it projects strongly onto the ocean and sea ice properties and circulation. This study investigates ...
Evaluation of Interior Circulation in a High-Resolution Global Ocean Model. Part II: Southern Hemisphere Intermediate, Mode, and Thermocline Waters
Publisher: American Meteorological Society
Abstract: A high-resolution, offline ocean general circulation model, incorporating a realistic parameterization of mixed layer convection, is used to diagnose pathways and time scales of Southern Hemisphere intermediate, mode, and ...
Causes of Late Twentieth-Century Trends in New Zealand Precipitation
Publisher: American Meteorological Society
Abstract: Late twentieth-century trends in New Zealand precipitation are examined using observations and reanalysis data for the period 1979?2006. One of the aims of this study is to investigate the link between these trends and ...
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 ...
Constraining Wind Stress Products with Sea Surface Height Observations and Implications for Pacific Ocean Sea Level Trend Attribution
Publisher: American Meteorological Society
Abstract: number of global surface wind datasets are available that are commonly used to examine climate variability or trends and as boundary conditions for ocean circulation models. However, discrepancies exist among these products. ...
Anomalous Rainfall over Southwest Western Australia Forced by Indian Ocean Sea Surface Temperatures
Publisher: American Meteorological Society
Abstract: The potential impact of Indian Ocean sea surface temperature (SST) anomalies in modulating midlatitude precipitation across southern and western regions of Australia is assessed in a series of atmospheric general circulation ...
Projected Changes to the Southern Hemisphere Ocean and Sea Ice in the IPCC AR4 Climate Models
Publisher: American Meteorological Society
Abstract: Fidelity and projected changes in the climate models, used for the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4), are assessed with regard to the Southern Hemisphere extratropical ocean ...
Contributions of Indian Ocean Sea Surface Temperatures to Enhanced East African Rainfall
Publisher: American Meteorological Society
Abstract: Links between extreme wet conditions over East Africa and Indian Ocean sea surface temperatures (SST) are investigated during the core of the so-called short rain season in October?November. During periods of enhanced East ...
