Lightning is a natural phenomenon which exists in the atmosphere due to the electron discharge process in very high current and short period. Among varioustypes of electron discharge, Cloud-to-Ground (CG) lightning has direct impact to human activity. Bogor is one of regions in Indonesia which has high intensity of lightning and rainfall. The aim of this research is to examine the <br /> <br /> <br /> <br /> <br /> <br /> <br /> connection between lightning, expecially the type of lightning, and the rainfall intensity in Bogor. <br /> <br /> <br /> <br /> <br /> <br /> <br /> The lightning data is obtained from station BMKG Lightning detector and rainfall data observation. The lightning and rainfall data are compared using Pearson or Spearman correlation method and rain-yiedl per flash (RYF) value calculation. The relationship between CG lightning activity and rainfall in Bogor in this <br /> <br /> <br /> <br /> <br /> <br /> <br /> research explains that the intensity between the amount of CG lightning struck and rainfall have a close relationship with r = 0,756. RYFvalueof CG lightning <br /> <br /> <br /> <br /> <br /> <br /> <br /> and rainfall relationship is 5.09 x 109 kg/fl. Lightning activity in Bogor areaitself occurs due to convective rain happened in the area.
