Urban effects on precipitation patterns in the greater Tel-Aviv are

The long-term trend in precipitation patterns at the greater Tel-Aviv area as well as in the surrounding regions has been statistically analyzed. It is shown that annual rainfall at stations within the boundaries of the Tel-Aviv metropolitan area as well as in downwind regions exhibit a significant increasing trend with respect to other stations in the area. The harmonic analysis applied to the annual rainfall march, averaged over two normal consecutive periods, reveals a shift in time of the peak value, occurring several days earlier during the second period. These changes in precipitation patterns seem to be affected by the extensive urbanization process.

Stadteinflüsse auf die Niederschlagsverteilung in dem weiteren Gebiet von Tel-Aviv


Es wurde der langzeitige Trend der Niederschlagsverteilung sowohl im weiteren Gebiet von Tel-Aviv wie auch in den umgebenden Regionen statistisch analysiert. Es wird gezeigt, daß der Jahresniederschlag an Stationen sowohl im Randgebiet der Stadt Tel-Aviv wie auch in windab gelegenen Gebieten einen signifikant zunehmenden Trend im Vergleich mit anderen Stationen in dem Gebiet aufweist. Die harmonische Analyse, angewendet auf den Gang des Jahresniederschlags, zeigt, gemittelt über zwei aufeinanderfolgende Normalperioden, eine zeitliche Verschiebung um einige Tage früher in der zweiten Periode. Diese Änderungen im Niederschlagsystem scheinen durch die ausgedehnte Stadtentwicklung beeinflußt zu sein.
