Results of ongoing investigations into patterns of interannual variability in total column ozone as measured by the Bureau of Meteorology’s Dobson network over the Australian region are presented. At all latitudes, total column ozone increases during winter and spring…
Analysis of zonal anomalies in total ozone and thermal tropopause height shows … that ozone depletion during austral spring has a strong influence on the height … and sharpness of the tropopause over West Antarctica. The seasonal change of tropopause … peak height occurs between 9 km…
The global distribution, sources, and propagation of atmospheric waves in the … equatorial upper troposphere and lower stratosphere were investigated using an … atmospheric general circulation model with T106L60 resolution (120-km horizontal … and 550-m vertical resolution).
A recently developed temperature-dependent semiempirical thermodynamic ion-exchange model is used to … predict ion-exchange equilibrium behavior of a binary and ternary system onto a natural zeolite material. The … ion-exchange system involves the cations ammonium, potassium, and calcium…
Iron(III)-uptake mechanisms in bacteria indigenous to the Antarctic, which is the most Fe-deficient … continent on Earth, have not been extensively studied. The cold-adapted, Antarctic bacterium, Shewanella gelidimarina, does not produce detectable levels of the siderophore, putrebactin…
