Abstract: A full understanding of the general characteristics of temporal and spatial distribution, and typical circulation patterns, and further the environmental conditions of thunderstorm high-winds (THWs) is vitally important to improve the quality of forecasting and warnings. By adopting the THWs obtained from national stations and automatic stations during 2015 and 2021, strict quality-control processes are executed, and the temporal and spatial characteristics, and circulation patterns of THWs in China were studied. The dominant weather regimes of THWs were classified objectively by adopting an empirical orthogonal function (EOF) analysis on the 500 hPa geopotential height followed by K-means clustering. The corresponding environmental conditions were then further investigated. The results show that (1) North China and Northeast China, the Jiangnan region and the South China region, the northwest part of Xinjiang, and the plateau region were the four high frequency regions of THWs (hereafter called Regions 1 to 4, respectively). THWs occurs the earliest in Region 2. The highest frequency of THWs was in June. (2) There are 4 types of circulation patterns in Region 1 and 3, while there are 5 types in Region 2 and 4. In Region 1, there are typical characteristics of cold vortices in the upper levels of each circulation pattern, and significant vortices and cold-warm confrontation in the lower levels. The proportion of circulation in one trough and one ridge is the highest, reaching 30.4%. Compared with Region 1, Region 2 is affected by various circulation configurations, such as the Southern trough, the eastern wave, the East Asian trough and the intertropical convergence zone. The strong West Pacific subtropical high alignment low-level convergence zone is the most frequent, accounting for 27%. The typical circulation patterns of thunderstorm high-winds in Region 3 is the fluctuation of west wind trough, the proportion has reached 52.4%. The South Asian High accounts for the highest proportion (52.7%) in Region 4. The upper trough is another major influence circulations that produces thunderstorm high-winds in the plateau region. (3) There are significant differences in the thermal dynamic conditions for generating thunderstorm high-winds in different regions. The THWs in Region 3 dominate by dry ones, while that in Region 2 dominates by wet ones. The THWs in Region 1 and 4 are mainly dry THWs. The THWs that was evaluated dry ones and highly related to cold vortex in Region 1 are likely to have low convective available potential energy (CAPE) and strong wind shear conditions. The peripheral subtropical high type in Region 2 and the South Asian high type in Region 4 evaluated wet ones are likely to have high CAPE and weak wind shear conditions. The results provide a solid reference for understanding and forecasting THWs in different regions in terms of circulations and environmental conditions.
