Grabe ang mga kulog (thunder) ngayon

[boybi]

Just a while ago, tuloy tuloy mga kulog dito sa amin, sobrang lakas na parang sumasabog na cannon. Nanginginig pa mga ilaw and chandeliers sa bahay. The past few days ganito lagi ang mga kulog. Is this because masyado nang polluted ang skies natin?

Dati naman hindi ganito mga kulog, kung mangyari man e sobrang bihira. Hindi kagaya ngayon na halos araw araw e ganito. Kakatakot.

specially kanina .. an lutong ng tunog ..

[blueguy]

^^^ Yup grabe...parang mga firecrackers at movie lights

[badkuk]

i'm more inclined to think that it's more because of global warming screwing up our weather. madalas na ngayon ung days sa sobrang init, followed by sobrang lakas na ulan, then init uli. i can't remember these things happening when i was a kid. kaya tuloy on/off tong sipon ko

Kung tuloy-tuloy yung mga kulog, it means na tuloy-tuloy din yung lightning that causes them.

I'm also inclined to think that their increased frequency is due to environmental imbalance. Or it could also be due to an increase in certain human activities, such as aircraft flying, since I hear these can artificially trigger lightning.

Pati kulog nagagalit na sa pag-taas ng gas. Yung kanina dahil natuwa sila sa kay GMA.

Anyone bothered to check PAGASA's website?

Without looking at computer forecast models (low - upper levels), it looks like a trough of low pressure circling around that cyclone to the southeast is moving from northeast to southwest. The thunderstorms mark the axis of that trough. It's confirmed because the winds over there are from a northerly orientation instead of the normal southwesterly direction of the southwest monsoon:

The satellite image is current. The thunderstorms are being sustained because at the low levels, the northeasterly flow of the trough is colliding with the southwest monsoon which had been pushed back west. There's nowhere for the warmer moister air to go but up. That provides added lift/punch for an already favorable tropical atmosphere resulting in more intense thunderstorms. That's the closest I can put it in layman's terms.

Add: It should be nice and cool relatively speaking at least for today over there if I go with my instincts. PAGASA don't think so. So, surface heating may cause more thunderstorms although I doubt they'll be as intense as the ones that came through.

There isn't much going on here once more. So, I'm looking at weather somewhere else.

And so I face the final (curtain)thunder

And so I face the final (curtain)thunder

My friend, Ill say it clear,
Ill state our case, of which Im certain that our planet is warming up.

[karlbo]

oo nga nung isang gabi tinawagan pa kami ng biyenan ko. kasi nasa labas pa kami ni
esmi nung mga oras na yun.. anlakas daw ng kulog sobra..
natatakot daw sila kasi wala silang ibang kasama sa bahay..
eh sa daan naman wala naman kaming naririnig or nakitang kidlat.
boom boom lang ng oto naririnig namin eh tsk tsk

The forecast for Manila International calls for thunderstorms over the airfield. But, with the wind flow coming from the north and northeast, it's a bit drier. I imagine, if the sea breeze and lake breeze (from Laguna de Bay) sets up with the accompanying wind direction shifts, then thunderstorms will be likely since the wind flows will converge right over Manila.

I'm still convinced there won't be thunderstorms over Manila today. But, I'm not an expert over there and more than likely, I'll be wrong. But, it's still a good exercise of the rules of thumb I use. I'll check observations from RPLL later and see what factors I missed.

Add: I already missed one factor..... I didn't realize how narrow the Philippines is near Manila. The east coast of the Philippines should see enhanced thunderstorm formation with both gradient wind flow and the sea breeze coming from the same direction. So, some thunderstorms that develop over the Philippine east coast east of Manila may cross over terrain into Manila itself.

Add: For the west coast of Luzon, it should be nice so long as the northerly/northeasterly wind flow continues.

napapdalas nga yun lightning and thunder. pag may thunder storm i would look out my window and see lightning from far away. kita kase samin ang manila bay area. at times lightning strikes in mid air sa clounds. nakakatakot talagkae one time may mataa na puno dito samin was hit by lightning. nagulat kame lahat nun kumulog na. nanginig pati mga windows namin at nag alarm yun kotse.

RPLL is the international 4-letter identifier for Ninoy Aquino International Airport. This is a list of observations taken by the weather folks at that airport arranged from the latest to the earliest. Times are in zulu. To get local time, I think it's add 8 hours. So, 1000Z would be 1800 local time or 6 pm.

It looks like the winds were from the north until 03Z/11AM when it shifted to a direction of 280, almost from due west. That's the sea breeze right there. Moisture would've been increasing from the west which coupled with the hot temperatures would've resulted in increasing clouds. 3 hours later, the observer at NAIA was carrying CB remarks on the observation. CB is short for cumulonimbus which are thunderstorm-producing clouds.

I guess it doesn't take much atmospheric dynamics for thnderstorms to occur over there.

really?
:bwahaha:

nasunog ba yung mataas na puno?

well kakatakot na talaga .. one time nakita ko isang billboard sa commonwealth was strucked by a lightning and biglasng nag bown out.. katakot

[safeorigin]

kaya umiinit ngayon ay dahil sa...

anyways, with regards to the lightning storms, ye it's caused by global warming because it creates more storms thus increasing the ionic disturbance of the athmosphere.

[nels76]

Naalala ko dati bago lumindol ng July 16 1990, anglalakas ng thunderstorms a few days prior to the earthquake.

Halos everyday at around 2 to 3PM for 1.5 weeks ata uulan then anglalakas nd kidlat at mababa pa ung altitude ng occurrence.

Pagkatapos ng earhtquake, may nakapansin na nawala na ung mga thunderstorms. may nabasa ako noon sa People's Journal na ung Thunderstorms prior to the earthquake were related as the grinding tectonic plates generate charges daw that cause the lightning.
Nabasa ko lang yon ha. Don't quote me on that.

[wildthing]

beneficial naman ang kidlat ah... it produces O3 (ozone) para madagdagan ang ozone layer at the same time ay mag-purify ng pollution sa hangin

apparently, malakas ang kulog kung malapit ka sa lightning activity at siguro mataas na ang build-up ng electrical charges sa lugar ninyo kaya panay ang kidlat dyan.

[v6dreamer]

Ang kulog ay sanhi ng kidlat na sumasabog sa kalangitan. Ang kidlat ay sobrang napakainit at itoy umaabot sa talumpung libo hangang limampung libo na grado. Dahil sa sobrang init kapag itoy tumagos sa hangin at sa mabilisang paginit nang hangin nagkakaroon ng maalon na pagsabog habang papalayo ito sa kidlat na sa tulin ay mas higit pa sa tulin ng ugong.

Dahil sa matinding umuugong na pagsabog itoy tinatawag natin na KULOG.
