“…The ascending radiosonde collects the temperature, pressure, relative humidity, wind and other meteorological elements as well as the latitude and longitude deviation at every 1.2 s (corresponding to a vertical resolution of about 8 m). Therefore, based on the radiosonde data during June-August from 2015 to 2021 from the 7 radiosonde sites, the relative humidity threshold method, which is commonly applied in studying the cloud of China and even the world (Cai et al, 2014;Li, Cai, & Zhou, 2021;Narendra Reddy et al, 2018;Wang et al, 2000;Wang & Rossow, 1995;Zhang et al, 2010Zhang et al, , 2018Zhou et al, 2020;Zhou & Ou, 2010), is used to detect the cloud layers over the SETP in this study. The details for the method to detect CVS can be found at the Text S1 and Table S1 in Supporting Information S1.…”
