KUALA LUMPUR: The Drainage and Irrigation Department (JPS) hopes to overcome flash floods in the Klang Valley, especially in Kuala Lumpur, by installing a new radar system that provides quick readings of rainfall.
JPS Hydrology and Water Resources Division director Datuk Hanapi Mohamad Noor said the Polarimetric Doppler weather radar system from Japan would cost about RM3mil.
He added that the system, capable of detecting the motion of rain droplets in addition to the intensity of the precipitation would be installed after discussions with the Malaysian Meteorological Department.
“The current Radar takes about 10 minutes to provide a record of rainfall but the new radar system can provide the required report in a minute,” he told Bernama after attending a seminar on ways to overcome floods through an initiative between the governments of Malaysia and Japan.
Radar data system are used to make short term forecast of future positions and intensities of rain, snow, hail, and other weather phenomena.
“JPS depends heavily on the radar in Subang, managed by the Malaysian Meteorological Department. We receive reports every 10 minutes but such data is not fast enough to forecast flash floods in the Klang valley,” said Hanapi. – Bernama
