The winter weather systems that cause snow and other phenomena in the Northern Hemisphere usually affect a certain region. For example, China is affected by the Siberian High, a massive collection of cold dry air that accumulates from September to April, Song Wenling, an expert from the National Climate Center, told China News Service on Sunday.

国家气象中心专家宋文玲6日对中新社表示，北半球引起降雪和其他现象的冬季天气系统通常只影响某一特定地区。例如，中国受西伯利亚高压的影响。西伯利亚高压是一种从9月至来年4月聚积的大规模干冷空气。

However, these systems are not separate because the hemisphere's atmospheric motion means they affect each other, she said, adding there may be some relation between the extremely cold weather.

宋文玲称，然而，这些天气系统并不是独立的，因为北半球的大气运动意味着它们会相互产生影响，极端寒冷的天气可能有某种关系。
