The Arctic Oscillation （AO） is known to have no direct relationship with the monsoon over the Maritime Continent （MC）. Thus, an index called the Siberian High（SH^Maritime Continent（MC） Index （SHMCI） is developed to represent the mean sea level pressure difference between the SH and the warm pool over the MC. This index indicates a strong link with the monsoon circulation. A positive （strong） value of the SHMCI is associated with strong meridional winds and intense and frequent cold surge events over the South China Sea. The correlation between the AO index and the SHMCI is -0.39, which is medium but statistically significant; however, it is not sufficiently conclusive to infer direct correlation. Nevertheless, the SHMCI can be used as a tool to relate the AO with the monsoon over the MC because of the influence demonstrated by the AO towards the SH. Further analysis on the convergence and divergence anomalies over the MC reveals an impact discernible only from the SHMCI. This implies that the SHMCI manifests clearly the relationship between the Arctic and equatorial climate.展开更多

文摘This paper attempts to establish a method for analysing the relationship between the polar and equatorial climate of the Northern Hemisphere. The Arctic Oscillation （AO） is known to have no direct relationship with the monsoon over the Maritime Continent （MC）. Thus, an index called the Siberian High（SH^Maritime Continent（MC） Index （SHMCI） is developed to represent the mean sea level pressure difference between the SH and the warm pool over the MC. This index indicates a strong link with the monsoon circulation. A positive （strong） value of the SHMCI is associated with strong meridional winds and intense and frequent cold surge events over the South China Sea. The correlation between the AO index and the SHMCI is -0.39, which is medium but statistically significant; however, it is not sufficiently conclusive to infer direct correlation. Nevertheless, the SHMCI can be used as a tool to relate the AO with the monsoon over the MC because of the influence demonstrated by the AO towards the SH. Further analysis on the convergence and divergence anomalies over the MC reveals an impact discernible only from the SHMCI. This implies that the SHMCI manifests clearly the relationship between the Arctic and equatorial climate.
文摘The Iran policy of Russia,China and India is one of ambivalence.While going along with the US-sponsored resolution in the United Nations to end the alleged Iranian nuclear weapon program,the three nations have been opposed to any“crippling sanctions”against Iran.The current paper analyzes this policy of ambivalence and attributes it to a curious mix of convergence and divergence of their interests with the Persian nation.It also recommends how Tehran could mould this policy in its favor.
