Results show that there are multi-time scale periodic variations in AOI, the temperature and precipitation in Northwest China with significant syntonic periods of qausi-3 a between AOI and the precipitation, while the multi-time scale correlations between AOI and the temperature are quasi-2 a, 3-5 a and about 8-11 a with the strongest coherency in 8-11 a syntonic period. The influence of AO on temperature is more remarkable than that on precipitation in Northwest China for the interaction of their interdecada1 variation.
