Results show that winter snowfall in the YHRB exhibits consistent anomalies over the whole region for the interannual variation during 1960–2012. Further analysis suggests that winter snowfall anomalies in the YHRB are closely linked to the anomalous wintertime SCAND activity. When there is more winter snowfall in the YHRB, SCAND is usually in a positive phase, accompanied by a strengthened Urals blocking high and East Asian trough, which is conducive to strengthened cold-air activity, intensified vertical motions, and more water vapor transport in the YHRB. In contrast, less winter snowfall in the YHRB usually happens in the negative phase of SCAND. Our results provide useful information to better understand the relevant mechanism responsible for anomalous winter snowfall in this area.展开更多

Scandinavian design, with simple but not easy product appearance and shape, perfect man-machine interface, and very humane exotic customs, has led the global design industry trend, touching consumers＇ hearts all over the world since several decades of years ago. Dematerialization factors bound in Nordic-design are the root cause of the classic achievements. Dematerialization fully contains human touch, human factors. This is focusing on people-oriented design concepts, reflecting the best harmonious development of the modern world＇s ideas and themes. This article mainly takes Scandinavian-product design as an example-furniture and industrial design, and makes further exploration and research of dematerialization factors contained by products.展开更多
