Abstract: | The interannual variation of the North Atlantic Oscillation (NAO) and North Pacific Oscillation (NPO) and its relationship
with the climate jump in the Northern Hemisphere in the 1960s, are discussed using the data analyses. It is clearly shown
that the amplitudes of the NAO and NPO were all increased obviously in the 1960s and the main period of the oscillations changed
from 3–4 years before the 1960s to 8–15 years after the 1960s. Therefore, the climate jump in the 1960s is closely related
to the anomalies of the NAO and NPO. |
