Australia's climate: Drought and flooding in annual rings of tropical trees

In the tropics, however, with only slight seasonal variations, the correlation is not so evident. Now scientists of the GFZ German Research Centre for Geosciences and their colleagues of the Australian National University have been able to prove that tree growth in north-east Australia depends mainly on the annual precipitation.
