Colombia rainy season floods kill 136

Colombia is experiencing its worst rainy season in at least 30 years, with at least 136 deaths over the past few months and 1.3 million people affected by flooding. Heavy rains in the capital of Bogota on Wednesday brought the Bogota River to its highest level in 30 years, and more rain is in the forecast--the latest forecast from the GFS model (Figure 2)--calls for an additional 3 - 6 inches (75 - 150 mm) in the Bogota region over the coming week.


Figure 1. Satellite-observed rainfall over Colombia during the past two weeks shows a region of 300 - 400 mm (12 - 16 inches) has fallen near Bogota. Image credit: Navy Research Lab, Monterey.

Colombia's rainy season usually peaks in October, then gradually wanes in November and December. The heavy rains are due to the presence of the Intertropical Convergence Zone, the area encircling the earth near the equator where winds originating in the northern and southern hemispheres come together. When these great wind belts come together (or "converge", thus the name "Convergence Zone"), the converging air is forced upwards, since it has nowhere else to go. The rising air fuels strong thunderstorm updrafts, creating a band of very heavy storms capable of causing heavy flooding rains. This year is a La Niña year, which means there is a large region of colder than average water off the Pacific coast of Colombia. Colder than average water off the Pacific coast enhances rainfall over Colombia, and this year's moderate-strength La Niña is largely to blame for Colombia's deadly rainy season.

I'll have a new post on Tuesday.

It is, thank you. Good folk, here. The WU community is a special group. I feel privileged to be a small part of it.


Very nice, PSL. You deserve a little something for that. As a matter of fact, all of you deserve this.

I know what you mean. Sort of sedimentary accumulations of the worst kind.
Look on the bright side. Our center of gravity is being lowered all the time. (although I cannot think WHY this should be a good thing, I am sure it is)

Helps with skiing. (Personal experience of not having same on the slopes.)

re 154

Atmospheric methane is on the move up again. It was thought that it woudl actually start decreasing after all the efforts to control it were enacted - they didnt figure on the time bomb in the Arctic. It wasn't even included in the 2007 IPCC report.



Thanks for that.
I did not realise that methane was on the up....

Yes, and I guess the big trick now is to get all those random molecules to stay together. I think most of mine have settled in my stomach. I am the same weight since I was 18. It is has somehow been redistributed.

Dont be concerned about the 'picking on the old folks' thing.
They have no idea how difficult it was to get all those random molecules to coagulate into us!

Indeed!
2" today, from a Low that is passing through.
Flew from Panama City to here yesterday, and was amazed at the enormous clouds looming over the plane (we were at 30,000 feet) over Columbia and Venezuela. Beautiful flight though the canyons and around the anvils.....
Had no idea that the situation in C. was so bad until I read this Blog.
The forecast is for more rain....Sounds like a cool flight.:)

Leaking Siberian ice raises a tricky climate issue

By ARTHUR MAX, Associated Press Arthur Max, Associated Press – Mon Nov 22, 12:00 am ET

CHERSKY, Russia – The Russian scientist shuffles across the frozen lake, scuffing aside ankle-deep snow until he finds a cluster of bubbles trapped under the ice. With a cigarette lighter in one hand and a knife in the other, he lances the ice like a blister. Methane whooshes out and bursts into a thin blue flame.

On this date in 1718 Blackbeard the pirate was killed in battle.

Also, while everyone knows that JFK was assassinated on this date, it is seldom remembered that two of the intellectual giants of the 20th century, Aldous Huxley and C. S. Lewis also died on November 22, 1963.

Almost indian summer weather here, upper 60s today.


All of that was covered in Post #15. Didn't you see the link? LOL

Warm and muggy here in Pcola tonight. We need another cool front. As always, I monger for snow during the winter months. Last year we had forcasts for snow more times than ever. I actually only saw flakes in the air for about two minutes, once. Best snow storm for Pensacola in my life was February of either 72 or 73. It stuck for a couple of days, had enough to build a real snowman on Pensacola NAS. About 3 inches on top of a layer of ice. That was something! I'd like to see it again someday. Have a good evening all.
