RISUse of the Temperature–Salinity Relation in a Data Assimilation Context
Publisher: American Meteorological Society
Abstract: A data analysis using conductivity?temperature?depth (CTD) measurements in the western tropical Pacific is carried out to get an estimate of the timescale over which temperature?salinity (T?S) relationships are preserved. ...
Diagnosing Natural Variability of North Atlantic Water Masses in HadCM3
Publisher: American Meteorological Society
Abstract: A study of thermally driven water mass transformations over 100 yr in the ocean component of the Third Hadley Centre Coupled Ocean?Atmosphere General Circulation Model (HadCM3) is presented. The processes of surface-forced ...
North Atlantic Subtropical Mode Waters and Ocean Memory in HadCM3
Publisher: American Meteorological Society
Abstract: A study of the formation and propagation of volume anomalies in North Atlantic Mode Waters is presented, based on 100 yr of monthly mean fields taken from the control run of the Third Hadley Centre Coupled Ocean?Atmosphere ...
Estimating Oceanic Heat Content Change Using Isotherms
Publisher: American Meteorological Society
Abstract: This paper presents a new analysis of ocean heat content changes over the last 50 yr using isotherms by calculating the mean temperature above the 14°C isotherm and the depth of the 14°C isotherm as separate variables. A ...
Interpretation of Water Mass Transformations Diagnosed from Data Assimilation
Publisher: American Meteorological Society
Abstract: This paper presents results from a global ocean model with ¼° resolution and 36 vertical levels, forced with European Centre for Medium-Range Weather Forecasts (ECMWF) winds and with applied altimetric sea level anomalies ...
Seasonal and Interannual Variability in a Model of the Mediterranean under Derived Flux Forcing
Publisher: American Meteorological Society
Abstract: A 100-yr integration of a Mediterranean Sea model is performed with surface restoring to monthly varying T, S, followed by 100 years of integration with surface fluxes of heat and freshwater alone. The fluxes are diagnosed ...
Effect of ENSO Phase on Large-Scale Snow Water Equivalent Distribution in a GCM
Publisher: American Meteorological Society
Abstract: Understanding links between the El Niño?Southern Oscillation (ENSO) and snow would be useful for seasonal forecasting, as well as for understanding natural variability and interpreting climate change predictions. Here, a ...
A Study of Temperature Changes in the Upper North Atlantic: 1950–94
Publisher: American Meteorological Society
Abstract: In this paper, decadal evolution of warm and cold anomalies in the subtropical and subpolar gyres of the North Atlantic in the 300?500-m and 100?250-m depth ranges is described. A series of pentadally averaged objective ...
Toward an Understanding of Deep-Water Renewal in the Eastern Mediterranean
Publisher: American Meteorological Society
Abstract: This paper presents a scenario for understanding the unexpectedly large changes of deep waters and thermohaline circulation in the Eastern Mediterranean during the past decade. It is demonstrated as a possible deep-water ...
Mechanisms Linking Volcanic Aerosols to the Atlantic Meridional Overturning Circulation
Publisher: American Meteorological Society
Abstract: his study examines the sensitivity of the climate system to volcanic aerosol forcing in the third climate configuration of the Met Office Unified Model (HadCM3). The main test case was based on the 1880s when there were ...
