Analysis of Continuous Thunderstorm in One Week at Qingdao Airport Based on Sounding Data.

Continuous thunderstorm occurring at Qingdao Airport in China from August 7 to 13, 2022 was analyzed based on sounding data. The weather was divided into thunderstorm gale, thunderstorm and heavy precipitation, and some physical quantities and time variables which can effectively identify severe convective weather types were preliminarily obtained. The results show that CAPE was sensitive to different types of weather, but the uncertainty was relatively large. Convective temperature TC0N, temperature difference between 500 and 850 hPa, and vertical wind shear can distinguish thunderstorm gale, thunderstorm and heavy precipitation weather obviously. Besides, K index, Showalter index, 0se difference between 500 and 850 hPa were also important basis to distinguish thunderstorm and heavy precipitation weather. Thunderstorm gale can be distinguished by the 24-hour variations of K index, and the difference of dew point between 500 and 850 hPa. The 24-hour variations of (-G) 500 and vertical wind shear can be used to distinguish between heavy precipitation and thunderstorm weather; the 24-hour variation of stratification stability Aöss can distinguish the three kinds of weather well. For the wind field, the existence of vertical wind shear was required for strong convective weather, and the 24-hour increment of thunderstorm gale and thunderstorm was larger than that of heavy precipitation.
