“Diurnal differences in the effect of aerosol on cloud-to-ground lightning in the Sichuan Basin”
Careful English editing is still needed. See the numerous technical comments. The discussion of Figure 10 is hard to follow and full of speculation. Please shorten.
L148: This sentence is confusing.
“In addition, within six hours before the start of each sample, the number of grids with CG lightning flashes records in each hour is less than 10% of the entire study region. This is to ensure that thunderstorm is …”
Is this what you mean?
“In addition, days when flashes occur in more than 10% of the study region during any of the six-hours (06-12 UT) preceding the sample period are removed to ensure that thunderstorm activity is …”
L184: You could argue that there is only one peak on clean days too with the peak lasting from 1700-0100 BJT. Do you believe the decrease in flashes between the two small peaks is significant or noise?
Low and Middle SHEAR –For simplicity, it might be best to use 850 to 700 hPa shear for low shear and 500 to 400 hPa shear for middle shear.
L280: “In the afternoon, the relationship between TCLW and T may contain the above two mechanisms, which leads to an insignificant relationship between them”
Is this what you mean?
“In the afternoon, for TCLW < 0.1 kg m-2, the change in T with increases in TCLW is small as both factors are in play”.
L281: At night, the absence” “At night, for TCLW < 0.1 kg m-2, the absence”
L269-296: This paragraph is difficult to follow. Ideally, it should be re-written – perhaps shortened.
L570: I’m not sure what you mean by “Black lines represent the 1500 m contour line”. Are you simply saying that the 1500 m altitude line is shown to highlight the location of the basin?
L15: “in the rest of the time” “during the remainder of the day”

L63: “Under the polluted condition” Under polluted conditions
L64” “occurrences were delayed in the day” occurred later in the day”
L66: “These researches” “These studies”
L90: “removed to eliminate the possible contaminations of intracloud flashes” removed because many of them may be IC flashes instead”
L91: “if more than one” “if multiple”
L91: “with 10 km” “within 10 km”
L92: “seconds assumed to be from the same flashes” “seconds are assumed to be from the same flash”
L110: “mainly select hourly reanalysis data of five factors” “select five variables derived from the reanalysis data”
L126: “its terrain of it” “the altitude of its terrain”
L131: “marked larger” “markedly larger”
L140-144: “… value of a sample. We limit the analysis to grid boxes with at least 1 CG flash during a 24-hour period beginning at 1200 BJT”. The sampling period is chosen to begin at 1200 BJT because flash rates are lowest at ~12 BJT (see Figure 2). The averaged AOD …”
L150: “Finally, we got 532 samples” “This filtering limited the data set to 532 samples”
L162: “gradually strengthened” “gradually strengthen”
L163: “lightning concentrated” “lightning is concentrated”
L171: “encountered” “encounters”
L199: “are almost large” ”are similar”

L229: character aerosol “characterize aerosol”
L245: “is different to them” “differs from those studies”
L251: “the difference in the lightning distribution has no great influence on its relationship with lightning” the relationship between wind shear and lightning does not vary much between the day- and night- periods”
L273: “and so does the direct radiation effect of aerosols, which has not significant impact on the surface temperature” “thus direct radiative effects are small and their impact on surface temperatures is minimal
L282: “promotion of surface temperature to” increase in surface temperature with”
L288: “direct impact of” “direct impact on”
L298: “the weakening effect of aerosols on surface temperature is dissipated” “the effect of aerosols on surface temperature is minor”
L315: “overlap” “counter”
L325: “the difference is more obvious in the rest time” but the difference is significant during the remainder of the period”
L332: “As the AOD is less” “When the AOD is less”
L339 and L341: “direct radiation” “direct radiative”
L348: “might apply” “should apply”
L349: “Moreover,” “As a caveat,”
L554: “for the period 2010-2018 including the summer months” for the summer months () of 2010-2018
L602: TCIW and (d, h) TCIW-T and (d, h)
L603: “Note that samples are first sorted by the variable on the x-axis and then samples with similar values of the x-variable were averaged …’
