QUALITY CHECK FOR IMPACT FOR HAZARD ASSESSMENT
Each cyclone track has been analyzed for its life cycle from formation to
dissipation. The life cycle of cyclone undergoes five stages from depression to sever
cyclone to depression.. The sectors of different intensities have been identified in
order to asses the exact impact of the system in that sector. For each sector
involving the different phase of system falling in the track, intensity, wind potential,
potential storm surge and period of residency of the system have been clearly
segregated in order to evaluate the hazard potential of the system in particular sector
CYCLONE HAZARD ASSESSMENT
The cyclone hazard assessment planning process requires maps of different
resolutions as given below in the table.
