The results showed that the continuous rainy and cold weather occurred after temperature increased in early days. It is mainly because that the high geopotential height near Ural Mountains lasted for a long time, while the geopotential height was abnormally low in the east of central Asia. Meanwhile, the Iow-prassure trough in the south of Qinghai -Tibet Plateau was very active and moved towards the east frequently, and subtropical high was strong. Compared with continuous rainy and cold weather in early 2008, during the process of this continuous rainy and cold weather in 2009, the decrease in sea surface temperature of the middle and eastern Pacific Ocean near the equator was weaker; the blocking high pressure was slightly weaker, and the low pressure over Mongolia was strong; subtropical high was stronger and showed zonal distribution; south trough was slightly weaker. Compared with the previous continuous rainy and cold weather, the duration of this continuous rainy and cold weather in 2009 was not the longest, and its sunshine hours were not the least, but its temperature was higher, which might result from obvious increase of temperature in the early days. The research could provide scientific references for the prediction of continuous rainy and cold weather in future.展开更多

Alongside entrepreneurial talent, the legal environment and system design are also very significant for SMEs' surviving. This Article provides the successful experiences of SMEs in YIWU, including raising sufficient capital from private finance, highly autonomous forms of enterprise, as well as thinking highly of intellectual property. This article analyses the current problems of SMEs from both legal and economic perspectives, and gives three proposals: legalising underground lending system and creating private banks, introducing the Limited Liability Company into China, and providing the road for transforming intellectual property rights into easily realisable interests, for the purpose of building a more advantageous developing environment for SMEs.展开更多
