Abstract: Thunderstorm high wind occurs on 3 June 2009 in the two adjacent regions under the influence of the subsynoptic scale tough, which is in the rear part of a cold vortex. These two wind areas are significantly different in terms of storm structure, surface high wind distribution and severity degree. The storm structure analysis results show that the Jinshan strong winds are caused by single-cell storms and pulse storms, and Shangqiu high winds are caused by typical bow echoes. Environmental factors of these two wind stroms are investigated based on the observation and numerical simulation, and the composite environmental temperature and humidity profiles are built. The results show that: (1) The Jinshan environment temperature and humidity profile is the "inverted V" profile, which is the typical sounding of dry microbursts. This kind of sounding is common at China's western plateau area in summer time. (2) The Shangqiu temperature and dew point profile is similar to typical wet downburst sounding. The high resolution numerical simulation results show the structure of an single-cell storm, that is, the outflow from old convection triggers new cells on it's leading edge. The cold pool is generated by the cold downdrafts of multiple isolated convection cells in relatively dry environment. High wind occurred at the position where cold pool density airflow is overlapped with downdraft divergence airflow of a relatively strong single-cell. The bulk vertical wind shear is weak in the two windstorm regions, and the strong vertical wind shear concentrate at low levels. The numerical simulation results show that under this vertical wind shear, lower humidity conditions determines the storm structure. Under a medium to high moisture environment, it is highly organized as squall lines. Under a low humidity environment, poorly organized single-cell storms or pulse storms are generated. The formation processes with respect to the different storm structures are described in detail at the last part of this article.
