BAMBANG, Nueva Vizcaya: In preparation for the rainy season and in time for the onset of the so-called typhoon months, the Department of Science and Technology (DOST) has installed a modern weather device in Cagayan’s coastal town of Aparri.
The DOST said that, for a more accurate weather forecasting, the “Doppler radar systems” installed recently in Aparri is one of the four radar systems acquired by the national government to upgrade its weather forecasting capability.
Lying along the China Sea-Pacific Ocean coast, the town of Aparri is a strategic point of reference in the country for weather disturbances originating in the North Pacific Ocean, according to DOST officials.
“The system is equipped with the latest weather monitoring technology with a range of 400 kilometers as against the old equipment which can only reach half of the distance,” said Urduja Tejada, DOST director for Region 2.
In Barangay Punta in Aparri, an old equipment is stationed which could only track rainfall, unlike the newly installed system which can estimate wind velocity as well as the amount of rainfall within its range.
Leo Bunag of the Aparri-based Philippine Atmospheric, Geo-Physical, Astronomical Services Administration (Pagasa) said “the new equipment would allow us to forecast rainfall in a given area based on the data gathered by the equipment.”
“With the instrument’s capabilities, concerned residents are given time to prepare for any eventualities and prevent the unnecessary loss of lives and property,” Bunag said.
A total of nine Doppler radar in the country has been established including those in Baguio City, Baler in Quezon, Subic in Zambales, Tagaytay City in Laguna, Virac, Catanduanes, Cebu, Surigao, General Santos City and Samar.
Bunag said all data monitored by these various Doppler radar are being sent directly to Pagasa in Manila for monitoring results and consolidation.|
Doppler radar systems have been utilized by more advanced countries providing more advance warnings on the strength, direction and volume of rainfall of approaching typhoons or storms or low-pressure areas.
