摘 要：In this study,the characteristics of environmental factors associated with typhoon Kongrey were examined using radiosonde,wind-profiler,radar,and Automated Surface Observing System(ASOS)data in Uljin,which is located the eastern coast of *** radiosonde data were obtained from intensive observation between 1500 LST 5 to 0000 LST 7 October *** factors such as Total Precipitable Water(TPW)and Strom Relative Environmental Helicity(SREH)were selected to examine their relations to typhoon-accompanied *** TPW peak with 60.54 mm appeared at 1200 LST 6 October,which is 6 h after the peak of typhoon *** was found that the TPW variation is largely associated with the effect of water vapor supply from the typhoon with nearest proximity to Uljin at 1500 LST 6 *** SREH,which indicates mechanical instability,was 761 m2 s-2 during the period in which typhoon precipitation *** environments would provide a good condition for the development of super-cell storms,causing heavy precipitation associated with *** addition,it was found that the correlation coefficient between SREH and typhoon rainfall is 0.8(p-value=0.02).
