Streszczenie:
Statistical models of atmospheric variability typically attempt to account for deterministic seasonal variations by constructing a long-term average for each day or month of the year. Year-to-year variability can then be treated as some form of stochastic process about this long-term average. In general, the stochastic processes are assumed to be statistically stationary (invariant under time translation). However, for a non-linear system such as the Earth’s atmosphere, multiple seasonal evolutions may be possible for the same external forcing. In the presence of such a multiplicity of solutio

Data from a number of sources are used to examine the climatology of the southern hemisphere middle atmosphere.

Mesospheric winds are used from a number of years of continuous partial reflection radar observations at four southern hemisphere sites. A comparison of the stratospheric analyses is used to highlight the regions of inadequacy in the data, and to assess its reliability. A three year zonal mean

The nature of blazars and the physical processes responsible for very high energy emission are also discussed. A signal above 700 GeV was observed from PKS 2155-304 between 1996 and 1997 but not in 1998 and 1999. One plausible explanation for this is a reduction in sensitivity of the Mark 6.Evidence for variability of high energy emission from PKS 2155-304 was search for but no firm conclusion was reached.

The dentition, adult feeding mechanism, pancreatic tissue and intestine have been studied in the anadromous parasitic lamprey, Geotria australis (Geotriidae; Petrorryzoniformes). For coirparative purposes, the feeding structures of parasitic adults representing the two other families of extant lampreys (Petromyzontidae and Mordaciidae) have been examined, as have the pancreas of nordacia mordax and intestine of Lampetra spp. Wherever possible, the results of these studies on the feeding biology of lampreys are compared with those reported elsewhere. Conclusions drawn from these conparisons are

Despite the long time since the introduction and spread of pine plantations in southern hemisphere countries there has been no study of the suitability of this exotic and novel type of vegetation on the native avifauna. This thesis aims to add understanding of this habitat replacement and its effects on the forest bird community. This research included a series of studies to assess the quality of mature pine plantations for the forest avifauna in comparison to what is in native forests. The first two studies determine the effects on the forest bird community of the fragmentation and replacemen

Streszczenie:
A mechanistic global circulation model is used to simulate the mesospheric and lower thermospheric circulation during austral winter. The model includes a gravity wave (GW) parameterization that is initiated by prescribed GW parameters in the troposphere. In standard configuration, these waves are described by a simple distribution with large amplitudes in the winter hemisphere and small ones in summer. Here we replace this distribution by a more realistic one, which is based on observations of potential GW energy using GPS radio occultations, but which is normalized to the same global mean am
