The fact that various parts of Tanzania have very different fluctuations in rainfall from year to year is pointed out. In this preliminary study, a simple analytical technique involving correlations between rainfall stations on an annual basis was adopted, the aim being to see whether regions showing similar fluctuations in rainfall could be defined. A regional subdivision of the country, not based on proximity, was apparent. The zones tended to have a northwest-southeast alignment, modified by the influence of relief features. Two more detailed analyses of rainfall fluctuations which are under way are described.


Es wird auf die Tatsache hingewiesen, daß in verschiedenen Teilen von Tanzania sehr unterschiedliche Schwankungen der Niederschlagsmengen von Jahr zu Jahr auftreten. In dieser vorläufigen Untersuchung wird ein einfaches analytisches Verfahren angewendet, das auf Korrelationen zwischen den Jahresniederschlagsmengen der Stationen beruht, mit dem Ziel zu zeigen, ob Regionen mit ähnlichen Schwankungen der Niederschlagsmengen abgegrenzt werden können. Dabei zeigte sich eine regionale Unterteilung des Staatsgebietes. Die Zonen zeigen eine Tendenz zu einer Erstreckung in Richtung Nordwest-Südost mit Modifizierung durch den Einfluß der Reliefformen. Es wird auf zwei ausführlichere Analysen der Niederschlagsschwankung hingewiesen, die in Vorbereitung sind.
