<abstract>
<p>The precipitation variations of Longxi area, northeast
margin of the Tibetan Plateau since AD 960 are reconstructed from Chinese
historical documentary records. These records show that since AD 960, the
precipitation of Longxi decreased and reached the lowest level at the end of
the 17th and the 18th centuries. After this period, the precipitation
gradually increased. The three short wet periods of Longxi in the last
millennium were: from the end of the 10th century to the early years of the
11th century, from the end of the 12th century to the early years of the
13th century and during the first half of the 20th century. The
precipitation variations coincide well with variations of the Northern
Hemisphere temperature and the atmospheric &lt;sup&gt;14&lt;/sup&gt;C concentration, as well
as the averaged &lt;sup&gt;10&lt;/sup&gt;Be concentration and the reconstructed solar
modulation record which show that solar activity may be an important driving
force of the precipitation variations of Longxi on multi-decadal to
centennial scales during the last millennium. Solar activity controls the
motion of the north edge of the Asian summer monsoon by affecting the Asia
summer monsoon intensity, the East Asian winter monsoon intensity and the
locations of westerlies, thus further dominating precipitation variations of
Longxi. Synchronous variations of Longxi precipitation and Northern
Hemisphere temperature may also be ascribed to the same control of solar
activity.</p>
