Abstract: Rainfall is one of the major causes of natural disasters such as flood, landslide, debris flow and flash flood. Monitoring of rainfall is one of the main issues to be addressed for avoidance or mitigation of such disasters. The rainfall monitoring has been typically done by rainfall gauges for many years, but since the mid-20th century, radar technologies have also been applied for rainfall monitoring. Recently X-Band Polarimetric that uses the dual polarisation technique radar technology has been developed and investigated by several countries such as Japan and the USA for the disaster preparedness application. However, the application of this weather radar is still limited in developing countries such as Malaysia where the floods, flash floods and landslide keep happened during the heavy rainfall. Meteorological Department of Malaysia is effectively using C-Band and S-Band radars for weather forecast and warning. Meanwhile, the Department of Irrigation and Drainage of Malaysia uses the network of the rain gauges for monitoring the rainfall at the ground level and issues an alert or warning regarding the hazard. Under such circumstances, through the systematic reviewed approach, the current status of rainfall monitoring systems and weather forecast applications included the disaster caused by heavy rainfall in Malaysia was reviewed. Further, the characteristics of weather radars of different bands that focused on wavelengths and analysis methods are also been studied. Case studies on X-Band Polarimetric radar applications in the disaster area are included to identify the information needed for the utilisation of the X-Band Polarimetric radar in Malaysia.
