According to our new definition, in the monsoon area of the SCS two of the following conditions should be satisfied: 1) At 850hPa, the southwest winds should be greater than 2m/s. 2) At 850 hPa, seq should be greater than 335K. The new definition means that the summer monsoon is the southwest winds with high temperature and high moisture. The onset of the SCS summer monsoon is defined to start when one half of the SCS area (105E ~ 120E,5N ~ 20N) is controlled by the summer monsoon. The analyzed results revealed the following: 1) The summer monsoon in the SCS starts to build up abruptly in the 4th pentad in May. 2) The summer monsoon onset in the SCS is resulted from the development and intensification of southwesterly monsoon in the Bay of Bengal. 3) The onset of the summer monsoon and establishment of the summer monsoon rainfall season in the SCS occur simultaneously. 4) During the summer monsoon onset in the SCS, troughs deepen and widen quickly in the lower troposphere of the India; the subtropical high in the Western Pacific moves eastward off the SCS in the middle troposphere; the easterly advances northward over the SCS in the upper troposphere.展开更多

Over the past 40 years, China's economic development has made great achievements, which may be regarded as a "miracle" of economic development. This economic miracle is reflected in the scale and quality of China's economic development. China's 4-decade economic development has not only brought great changes to Chinese society, but also has a profound impact on the growth and development of the world economy. However, this does not mean that China has found a complete new road to economic development. China needs to correctly view its achievements in the 40-year reform and opening-up, and accelerate the transformation and upgrading of economic development in a new era, so as to make a greater contribution to the sustainable development of the world economy.展开更多
