A Dissertation Submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, for the Degree of Master of Science Johannesburg, 1997 / The palaeoclimate of southern Africa for the last twenty thousand years is investigated through the production of palaeoclimate maps based on an analysis of literature and data from the ongoing PASH project. The trends from the maps are compared with published reviews and modelling studies of the region' s palaeoclimates, and are contextualised in terms of global palaeoceanographic and palaeoclimatic dynamics. The changes evident in the past climate of southern Africa tend to mirror global climate changes, however, evidence exists that the timing of climate changes between the two hemispheres are not quite synchronous, and may 110tfit present theories of global palaeoclimate dynamics,

In this thesis we study measures of verification, accuracy determination, and implementation of limited-area research and operational weather prediction models. We give a complete description of the implementation of the multivariate autoregressive research model. This includes a FORTRAN program and three order selection routines. We conclude with a discussion on possible extensions of our results and other applications. / M.S.

(English) RNDr. Monika Cahynová: The influence of long-term changes of atmospheric circulation on observed trends of surface climatic elements in the Czech Republic and Europe The aim of this thesis is to quantify the links between recent atmospheric circulation changes over Europe and local surface climatic trends. We employ several parallel classifications of circulation types that were collected and developed within the COST733 Action "Harmonisation and Applications of Weather Types Classifications for European Regions". To our knowledge, such a comparative approach has not been used so far. Atmospheric circulation changes over Europe were studied in terms of changing seasonal frequency and persistence of daily circulation types in the second half of the 20th century. The extensive collection of both subjective and objective catalogues of circulation types in European regions from the COST733 Action served as a platform for comparison of different classification methods, varying numbers of circulation types, and spatial scale of circulation processes. The most prominent trend - winter increase in the number of days with westerly flow - clearly stems from the strengthening of the North Atlantic Oscillation. The objective classifications did not show any systematic change of persistence of...
