	<abstract content_type="html">We use measurements of recent decades, 1500-yr proxy data, and millennium
model simulations with a variety of climate facings to study the temporal
and spatial variability of summer precipitation over eastern China. Spectral
analysis of the proxy data using multi-taper method reveals three
statistically significant bidecadal (15&amp;ndash;35-yr), pendadecadal (40&amp;ndash;60-yr), and
centennial (65&amp;ndash;170-yr) oscillation bands. The results of wavelet filtering
show that the amplitudes of these bands vary substantially through time
depending on the temperature regimes. Weak centennial oscillation and strong
pentadecadal oscillation occur in warm conditions, whereas the
 oscillations are both strong in cold conditions. A
model/data intercomparison suggests that the centennial oscillation might be
linked to the fluctuation of solar forcing (Gleissberg cycle), and the
pentadecadal and bidecadal oscillations could be associated with internal
variability of the climate system. It is also found that the increased
frequency of drought-in-north/flood-in-south spatial pattern over eastern
China during the last two decades is unusual in the past five centuries.</abstract>
