Decadal variability in the Southern Hemisphere
[1] This study reveals that a quasi‐decadal variability exists in the climate system of southern high latitudes, particularly in the Southern Annular Mode (SAM) and subpolar to mid latitudes sea surface temperature (SST), based on in situ observations, reanalysis data, and the 20th Century runs of IPCC AR4 coupled climate models. Spectral analysis reveals that a statistically significant variab...
متن کاملDecadal-Scale Temperature Trends in the Southern Hemisphere Ocean
Long-term trends in the heat content of the Southern Hemisphere ocean are evaluated by comparing temperature profiles collected during the 1990s with profiles collected starting in the 1930s. Data are drawn both from ship-based hydrographic surveys and from autonomous floats. Results show that the upper 1000 m of the Southern Hemisphere ocean has warmed substantially during this time period at ...
متن کاملEmpirical estimation of the annual range of monthly-mean temperatures
This is a sequel to a study of the empirical estimation of the annual-mean temperature at any location on land, using only geographical information – latitude, elevation, distance from the nearer ocean shore at the same latitude – and coastal sea-surface temperature. Here long-term mean station data and NCAR=NCEP (National Center for Atmospheric Research=National Centers for Environmental Predi...
متن کاملOn the Annual Variation of the Monthly Mean Meridional Circulation
Data for a 5-yr period from a dense network of upper air stations have been used to determine the annual cycle in the mean meridional circulation north of 15's. Only during the transition months April, May and October, November is there some degree of symmetry with respect to the Equator. During the other months of the year, the Hadley cell of the winter hemisphere with a maximum strength of ab...
متن کاملAerosol climate feedback due to decadal increases in Southern Hemisphere wind speeds
[1] Observations indicate that the westerly jet in the Southern Hemisphere troposphere is accelerating. Using a global aerosol model we estimate that the increase in wind speed of 0.45 ± 0.2 m s decade 1 at 50–65 S since the early 1980s caused a higher sea spray flux, resulting in an increase of cloud condensation nucleus concentrations of more than 85% in some regions, and of 22% on average be...
