Here, severe convective weather mainly refers to intense local heavy precipitation, thunderstorm-induced gale-force winds including those from tornadoes and downbursts, and hail and lightning. These types of severe weather are usually small in spatial scale and rapid in their development, and are therefore difficult to capture by observational networks and are poorly resolved in typical operational numerical weather prediction （NWP） models. Furthermore, many of the important dynamic and physical processes involved are not well understood. Within China, the impacts of severe convective weather rank only after those of landfalling typhoons and widespread heavy precipitation and flooding. Studies （e.g., Zhang and Zhai, 2011） have shown tendencies for an increased frequency in short-duration extreme precipitation during the past several decades over most of eastern China, where the population is most dense. An in-depth understanding of severe convective weather in China, as well as being able to accurately predict it, is clearly of great importance.展开更多

The excess productivity has been so serious that it was calculated to be over 100 million tons more than needed only in China. This has caused a very heavy competition in the steel industry and the only way for a steel company to survive is to increase the competitiveness.展开更多

The areas of endemic KBD are relatively stable and are correlated with specific geographical environments. In China, estimation of KBD patients in 1985 indicated more than 2 million people were severely affected in a broad region inhibited by over 30 million people. KBD endemic areas form a broad belt extending from northeast to southwest. The disease mostly appears in mountainous and hilly regions, and farmers are the major potentially affected ones. Hence KBD has been designated a national health priori-ty problem in China since 60’s.展开更多
