Wettest year on record in Philadelphia; 2011 sets record for wet/dry extremes in U.S.

By: Dr. Jeff Masters , 3:00 PM GMT on December 12, 2011

This year is now the wettest year in nearly 200 years of record keeping in Philadelphia, Pennsylvania. A large, wet low pressure system soaked the Northeast U.S. on Wednesday and early Thursday, bringing 2.31 inches of rain to the City of Brotherly Love, bringing this year's precipitation total in Philly to 62.26 inches. This breaks the old yearly precipitation record of 61.20 inches, set in 1867. In a normal year, Philadelphia receives about 40 inches. According to wunderground's weather historian Christopher C. Burt, this is one of the most difficult U.S. city records to break, since rainfall records in Philadelphia go back to 1820. The only other sites with a longer continuous precipitation record in the U.S. are Charleston, SC (1738 -) and New Bedford, MA (1816 -).

20+ inches above average precipitation in Ohio Valley, Northeast
Philadelphia is not alone in setting a wettest year in recorded history mark in 2011. Over a dozen major cities in the Ohio Valley and Northeast have set a new wettest year record, or are close to doing so. Thanks to rains associated with this year's tremendous tornado outbreaks in April in May, plus exceptionally heavy summer thunderstorm rains, combined with rains from Tropical Storm Lee and Hurricane Irene, portions of at least twelve states have seen rains more than twenty inches above average during 2011.



The fraction of the country covered by extremely wet conditions (top 10% historically) was 32% during the period January through November, ranking as the 2nd highest such coverage in the past 100 years. And if you weren't washing away in a flood, you were baking in a drought in 2011--portions of sixteen states had precipitation more than twenty inches below average (Figure 1.) The fraction of the country covered by extremely dry conditions (top 10% historically) was 22% during the period January through November, ranking as the 8th highest in the past 100 years. The combined fraction of the country experiencing either severe drought or extremely wet conditions was 56% averaged over the January - November period--the highest in a century of record keeping. Climate change science predicts that if the Earth continues to warm as expected, wet areas will tend to get wetter, and dry areas will tend to get drier--so this year's side-by-side extremes of very wet and very dry conditions should grow increasingly common in the coming decades.

Percentage of the contiguous U.S. either in severe or greater drought (top 10% dryness) or extremely wet (top 10% wetness) during the period January - November, as computed using NOAA's Climate Extremes Index. Remarkably, more than half of the country (56%) experienced either a top-ten driest or top-ten wettest year, a new record. Image credit: NOAA/NCDC.

Unofficial state yearly precipitation record set in Ohio
The Wilmington, Ohio NWS office announced last week that three stations in Southwest Ohio had unofficially broken the 140-year old state yearly precipitation record. Cheviot, Miamitown, and Fernbank have recorded 73.81", 71.89", and 70.85", respectively so far in 2011, beating the old record of 70.82" set at Little Mountain in 1870. According to wunderground's weather historian Christopher C. Burt, the old record should be 72.08” at Mt. Healthy, Ohio in 1880.

Wunderground's weather historian Christopher C. Burt summarizes the global weather extremes in November in his latest post.

Quoting Coldwellrnd:
I see StormTracker2K how you operate now. Pad your numbers with approximately 350 comments of nonsense and the same old BS weather maps we see from you on a daily basis before you begin your AGW campaign.

Rack up blog numbers to full others of your supreme credibility before the AGW BS comes out and starts working toward that Neapolitan-Skyepony anti-capitalist agenda.

Really smart there. Really smart. One problem. It feel a bit short.

Good try.

Play again sometime.

For those of us who have to sleep whilst most of the fun is going on over on your side of the cauldron, we might ask? Has anybody got a copy of the post at 255? So as we can at least pulse the pasted copy, should we also recognise the significance of it.

This sadly reminds me of one of my favourite Carl Sagan quotes:

Think of how many religions attempt to validate themselves with prophecy. Think of how many people rely on these prophecies, however vague, however unfulfilled, to support or prop up their beliefs. Yet has there ever been a religion with the prophetic accuracy and reliability of science?

Given the rather generic nature of that particular biblical "pearl" of wisdom, it's a wonder the world got beyond AD79, let alone the AD540s etc . . .

Kind of went down a rabbit hole on that. I think we can boil down Nea's reply to his last sentence.

"The Munich Re graph I produced in #173 doesn't refer at all to damage amounts or insured losses; it's just the plain numbers of natural disasters as defined by the UN."

I think sar's post qualifies as number 2 on the list of 38 ways to win any argument.

Use different meanings of your opponent%u2019s words to refute his argument.


Better read that again, Sluggo. Nea didn't clarify the alleged source of the Munich Re graph until after I asked him, after his first post. I'm perfectly capable of reading, a skill you should work on. Still haven't seen any refererence from Munich Re that these are just UN numbers. Also haven't seen any response to the question about a company like Munich Re wanting to have more loss-causing weather events as a reason to raise premiums. Every graph tells a story, but not all tell the truth. I'm not willing to accept one graph as proof that we've seen a steadily inceasing number of damaging weather events without knowing the definitions and who's doing the counting.

US, Israel shocked by undamaged captured drone

Iran displays captured US RQ-170 drone

Iran exhibited the top-secret US stealth drone RQ-170 Sentinel captured on Sunday, Dec. 4. Its almost perfect condition confirmed Tehran's claim that the UAV was downed by a cyber attack, meaning it was not shot down but brought in undamaged by an electronic warfare ambush.
This is a major debacle for the stealth technology the US uses in its warplanes and the drone technology developed by the US and Israel.

The state of the lost UAV refutes the US military contention that the Sentinel's systems malfunctioned. If this had happened, it would have crashed and either been wrecked or damaged. The condition of the RQ-170 intact obliges the US and Israel to make major changes in plans for a potential strike against Iran's nuclear program.

SIGNIFICANT COMET PLUNGES TOWARD THE SUN: A comet nearly as wide as two football fields (200m) is plunging toward the sun where it will most likely be destroyed in a spectacular light show on Dec. 15/16. Although Comet Lovejoy (C/2011 W3) could become as bright as Jupiter or Venus when it "flames out," the glare of the sun will hide the event from human eyes. Solar observatories in space, however, will have a grand view. Yesterday the brightening comet entered the field of view of NASA's STEREO-B spacecraft:

Comet Lovejoy? More like Comet Killjoy! I was hoping it would blow up the sun!
