| 摘 要： | Based on the CINRAD Doppler radar data in Guangzhou and the lightning data in 2004 by power suppliers of Guangdong, statistical study is done by overlaying lightning’s position on radar’s echo. The result shows the followings. The concentrated period in which more negative lightning occurred at the middle levels (2 – 14 km), where radar echo was moderate (12 – 45 dBz), rather than at the low levels with the weakest echoes or at high levels with the strongest echoes. At levels 3 – 11 km, where the radar echo was between 10 dBz and 35 dBz, the area of negative lightning was much larger in central Guangdong than in the rest of the province. At levels 0.5 – 7 km where the radar echoes were between 44 dBz and 51 dBz, the probability for a point to have negative lightning varies from 0.4 to 0.7. |

| Abstract: | Based on the CINRAD Doppler radar data in Guangzhou and the lightning data in 2004 by power suppliers of Guangdong, statistical study is done by overlaying lightning's position on radar's echo. The result shows the followings. The concentrated period in which more negative lightning occurred at the middle levels (2 - 14 km), where radar echo was moderate (12 - 45 dBz), rather than at the low levels with the weakest echoes or at high levels with the strongest echoes. At levels 3 - 11 km, where the radar echo was between 10 dBz and 35 dBz, the area of negative lightning was much larger in central Guangdong than in the rest of the province. At levels 0.5 - 7 km where the radar echoes were between 44 dBz and 51 dBz,the probability for a point to have negative lightning varies from 0.4 to 0.7. |
