Weather: PAGASA March 2016 Rainfall Map



For the previous report, please click here.



INTRODUCTION. The Philippines has been feeling the effects of extreme El Niño since early this year, bringing about parched fields and mountain areas across the country, with Mindanao facing the worst dry spell and drought in recent history. Factually, we heard of news about forest fires in Mounts Apo and Kitanglad, both located in parts of Mindanao Island which received rainfall that are below the normal average since last year 2015. Many farmers in Mindanao marched their way to the national highway in Kidapawan City to call attention of relevant authorities and to ask for aid because the land is too dry to support farming, that protest shocked everyone when it lead to the bloody confrontation with the police on March 31. Luzon and Visayas were also not spared from the gravity of the 2015-2016 El Niño phenomenon as dams continue to register decrease in water level. The data below will tell you that March 2016 may go down in history as one of the driest months in the Philippines.

Weather: PAGASA February 2016 Rainfall Map



INTRODUCTION. The El Niño (lit. the little boy) is an unusual rise in the sea surface temperature along the Pacific Ocean, which brings changes in weather patterns across much of the countries facing the Pacific. In the Philippines, El Niño means lower amount of rainfall which may result in dry spell and drought. As early as 2014, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA, the Philippine official weather agency) has been warning the public of an imminent El Niño, only in mid-2015 did they confirm the country is experiencing “mild El Niño,” and is in danger of facing hotter and drier months.

All Doppler radar stations are owned by PAGASA-DOST and such data are being shown via Project NOAH and ClimateX.

Notes:
Online - radar images/animations from the PAGASA radar station can be seen in Project NOAH and/or ClimateX websites.
Operational but not online - these Doppler radars are working but not yet available online.
Station under construction - future Doppler radar stations of PAGASA, construction not yet completed, however, the weather bureau is hoping that these stations may finally be operational by the end of the year.

Doppler radar images below show their 240 kilometer (km) coverage, but they have the capacity to cover as far as 480 kms. especially during severe weather conditions.

{E} Didn't Hinatuan Radar really work in the wake of Typhoon Pablo?


Recently, I read a news article from Mindanews.com dated Dec. 6, 2012 saying that Philippine president Noynoy Aquino was not aware that the country's state weather agency PAGASA's[1] Doppler radar station (or equipment) in Hinatuan, Surigao del Sur was not working at the time Typhoon Pablo[2] ravaged the supposed "typhoon-free" Mindanao.

Interior and Local Government Secretary Mar Roxas himself was not aware of the problem, and said that the President was not noted about it.

The eye of Typhoon Pablo (Bopha) over Davao Region
as shown in this Doppler radar imagery from the Hinatuan station.
From PAGASA's Facebook page
But, PAGASA's Facebook page posted one of Hinatuan radar's images showing the eye of Pablo over somewhere between Davao Oriental where it made landfall and the adjacent province of Compostela Valley December 4 morning.

I'm not saying that the news is completely wrong. No. The reporter(s) who asked Sec. Roxas perhaps consulted the Project NOAH website for the rainfall amount Typhoon Pablo had. And at that time, the Hinatuan radar is "under maintenance" (sorry, I don't have snapshots of it for proof), so he/she/they may had concluded it as "down".

Nevertheless, with that image as basis, Hinatuan radar station was really working at that time.

I think, it is just the "connectivity problems" of the radar equipment with Project NOAH which was needed for resolution.

So this time, we cannot blame the radar equipment again for the loss of more than a thousand people, two years in a row.

Sorry peeps.

The thing is, our Doppler radars are now reliable in giving us rainfall updates in most parts of the country. I can't wait for all of them to appear in Project NOAH. I'm so excited to see it, very soon.

(Sorry to those who may have been struck and hurt by this blog post. I just based everything "on facts, not fiction".)
