This book provides a comprehensive overview of numerical weather prediction (NWP), focusing on the application of the spectral method in NWP models. The author illustrates the use of the spectral method in theory as well as in its application to building a full prototypical spectral NWP model, from the formulation of continuous model equations through development of their discretized forms to coded statements of the model. The author describes the implementation of a specific model PEAK (Primitive-Equation Atmospheric Research Model Kernel) to illustrate the steps needed to construct a global...

Warum Mathematik lernen ...... wenn man doch ohnehin einen Taschenrechner am Handy hat? Warum sich in der Schule mit endlosen Formeln und Rechnungen quälen? Es heißt doch nicht umsonst: Das werde ich später nie brauchen!Andreas Ehrendorfer belehrt Sie eines Besseren: In 17 Geschichten aus seinem Leben zeigt er, wie viel Spaß Mathe machen kann und wie häufig wir unser in der Schule erworbenes Wissen über Mathe im Alltag einsetzen (können, wenn wir wollen).Sie empfinden Qualen nach Zahlen, wollen aber trotzdem wissen, wie Magier auf der Bühne mit Zahlen jonglieren, wie wir durch...

Paleobotany has enormously expanded the documentation of fossil plant groups, floras and vegetation types, supporting its conclusions by technically much improved analyses of microfossils (pollen) and anatomical details. An increasing quantity and quality of all these informations from the geosciences is available when we follow the history of the biosphere up to the present. Simultaneously, research from the biosciences on the morphology, ecology, distribution, systematics and evolution of extant vascular plants, and on the ecogeographical differentiation of the vegetation cover of our...

Palynology, the science of fossil and recent spores/pollen grains, is of high importance, both in many pure and applied fields of the natural sciences (e.g. in botany, geology, climatology, archeology and medicine). It is not only an auxiliary science, but can certainly stand for itself. The "classical" palynology subjects, pollen morphology and systematics, are at present influenced by many modern approaches, e.g. from cell biology, analytical electron microscopy, morphometry, up to com- puter-aided-design of threedimensional reconstruction. In recent years fascinating informations have come...
