シベリア高気圧
The Siberian High affects the weather patterns in most parts of the Northern Hemisphere: its influence extends as far west as Italy, bringing freezing conditions also in the warm South, and as far southeast as Malaysia, where it is a critical component of the northeast monsoon. Occasionally a strong Siberian High can bring unusually cold weather into the tropics as far southeast as the Philippines. It may block or reduce the size of low-pressure cells and generate dry weather across much of the Asian landscape with the exception of regions such as Hokuriku and the Caspian Sea coast of Iran that receive orographic rainfall from the winds it generates. As a result of the Siberian High, coastal winters in the main city of Pacific Russia Vladivostok are very cold in relation to its latitude and proximity to the ocean.
