| Abstract: | This essay discusses the possibility of monitoring lightning by EOS/MODIS polar satellite.According to the atmosphere and cloud radiation theory,and the cloud water drops Mie scattering theory,the information of lighting caused by strong convective cloud clusters during the night can be extracted from middle and thermal infrared channels of EOS/MODIS satellite data.The possible occurring range of hailstone can be determined by the cloud-top temperature of strong convective satellite cloud image.Thus we can have macroscopic information for disaster reduction and disaster prevention. |

| Keywords: | strong convective cloud clusters lighting information Mie scattering cloud-top temperature |
