Sean brushes Bermuda; largest wave ever surfed; Tipton tornado an EF-4
Posted by: Dr. Jeff Masters, 3:26 PM GMT on November 11, 2011 +21
Tropical Storm Sean brushed by Bermuda this morning, bringing winds near tropical storm force to the island. Top sustained winds at the Bermuda airport were 37 mph this morning, and a gust of 56 mph occurred at 4:38 am AST. Dry air disrupted the circulation of Sean before it reached Bermuda, and the island picked up just 0.08" of rain as of 10 am AST today. Sean is headed northeastward, out to sea, and will cease to exist later today or on Saturday. Sean may not be the last storm of the season, however. The most recent runs of the GFS, NOGAPS, and ECMWF models all predict an extratropical storm capable of transitioning to a subtropical or tropical storm will form in the middle Atlantic late next week. If such a storm did form, it would be called Tammy, and would not threaten any land areas.

Largest wave ever surfed
A new world record was set this week for the largest wave ever surfed. On Tuesday, November 8, Hawaiian big wave rider Garrett McNamara caught a 90-foot (27 meter) wave during a tow-surfing session just offshore of the small fishing village of Nazare, Portugal. An undersea canyon 5000 meters deep runs very close to the shore, and the unique bathymetry is known to create unusually large waves when west-northwest swells affect the coast. On Tuesday, an approaching cold front extending southwards from a low pressure system centered just south of Iceland generated strong winds off the coast of Portugal, and a west-northwest swell of 8 meters (26'). The canyon generated three big waves in excess of 60 feet that day, and McNamara was able to catch the tallest, 90-foot wave. The previous record highest wave surfed was a 77-foot (23 meter) wave caught in 2008 at Cortes Bank off the coast of Southern California by Mike Parsons.

November 7 Tipton, Oklahoma tornado rated an EF-4
The powerful tornado that hit Tipton, Oklahoma on November 7 has been rated an EF-4 by the National Weather Service. The Tipton tornado hit two Oklahoma Mesonet stations and destroyed them; the Tipton mesonet site measured winds of 86.4 mph and the Fort Cobb site measured winds of 91.4 mph before destruction. The tornado was one of a family of six spawned that day by the parent supercell thunderstorm. The Tipton tornado is the first November EF-4 tornado in Oklahoma's history, and one of only twenty EF-4 or stronger November tornadoes observed in the U.S. since 1950, according to the Tornado History Project. There have been twelve December EF-4 tornadoes and two December EF-5 tornadoes observed in the U.S. since 1950. The confirmed tornado count for 2011 is 1543, putting this year in third place so far for most tornadoes, behind the 1692 tornadoes observed in 2004 and 1817 tornadoes in 2008. By the time the year ends, 2011 should wind up with 1600 - 1700 confirmed tornadoes.

Have a great weekend, everyone, and I'll be back Monday with a new post.

This is the Tipton-Snyder, OK tornado. This supercell produced multiple tornadoes over a couple of hours.

We had some nasty winds in the Colorado front range the past few days. Last night they caused damage in Georgetown, CO along I-70 and turned over several semi trucks along the freeway. Locals said it was some of the worst winds they've experienced in about a decade.

Grothar, post 502.
As can be seen from your Map, there is plenty of Red and Green all over the place.
This tends to indicate (to the Observant) that it could possibly be raining somewhere in Northern South America.
From careful and persistent Observations here, I can confirm the following--
1- it has indeed rained
2- it has rained on-and-off every day for weeks
3- the gardens are Swampy Bogs of Evil Smelling mud
4- there is no prospect for sunshine until tomorrow morning(it being night time)
5- and anyway, it will doubtlessly rain again tomorrow

See? Your map is filled with Spurious yet Strangely Accurate Information.
I trust you have a Pleasant Evening.
And ask that tomorrow you post a map that has none of those bright colours on it.

With thanks,
The Residents of Boggy Spong.

Quoting weatherbro:
Waves have been getting smaller here(since I moved here in 1991). Is there some kind of 15-30 year ocean oscillation I'm not aware of(where average wave heights increase and decrease)?
Well you'd have to look at buoy data before you could accurately determine what changes have occurred with average wave height.

It does makes sense that the average wave height for a given area does change over time. Large scale ocean oscillations (such as the PDO, AMO, or ENSO) have a large influence on global ocean temperatures and, as a result, also have large complications on the global atmosphere. Since waves are created by winds in the atmosphere, large scale oscillations certainly would have an impact on the average wave height for a location.

Certainly.
Without going to check, my understanding of 'spurious' is 'information that can be, or indeed may not be correct.
As in your map.
I mean, can we TELL that it is raining anywhere, from that?

Please feel free to correct my use of the word if I am in error.
But know that I will never talk to you again.

Soyuz Booster Rocket
JSC2011-E-209247(10 Nov. 2011)---The first stage engines of the Soyuz booster rocket are visible as engineers mated the rocket with the Soyuz TMA-22 spacecraft at the Baikonur Cosmodrome in Kazakhstan Nov. 10, 2011. Preparations continue for the Nov. 14 launch from Baikonur to the International Space Station with Expedition 30 Commander Dan Burbank of NASA, Soyuz Commander Anton Shkaplerov and Flight Engineer Anatoly Ivanishin aboard. Photo credit: NASA/Victor Zelentsov


New Crew Members Set for Launch to Station

A new trio of International Space Station residents, Expedition 29 Flight Engineers Dan Burbank, Anton Shkaplerov and Anatoly Ivanishin, are set to launch from the Baikonur Cosmodrome in Kazakhstan at 11:14 p.m. EST Sunday (11:14 a.m. Baikonur time Monday) aboard the Soyuz TMA-22 spacecraft.

In preparation for Sunday’s launch, the Soyuz TMA-22 spacecraft is scheduled to roll out to the launch pad Friday morning. The rollout will not be seen live on NASA TV. Video of the rollout will be played on NASA TV at 12 p.m. Friday. Photos of the rollout will be posted on http://www.flickr.com/photos/nasahqphoto/ when they become available.

Burbank, Shkaplerov and Ivanishin will join Expedition 29 crewmates Commander Mike Fossum and Flight Engineers Satoshi Furukawa and Sergei Volkov when their spacecraft docks to the Poisk mini-research module at 12:33 a.m. Wednesday.

Five days later Expedition 29 will end when Fossum, Furukawa and Volkov return home inside the Soyuz TMA-02M spacecraft. The trio is scheduled to undock from the Rassvet mini-research module Nov. 21 and land in Kazakhstan at 9:25 p.m. Expedition 30 will officially begin when the Soyuz TMA-02M undocks. Burbank will take over station command in a ceremony scheduled to take place on Nov. 20.

Aboard the orbiting International Space Station Thursday, Fossum, Furukawa and Volkov continued preparations for their upcoming departure, gathering and packing gear for return to Earth inside the departing Soyuz spacecraft. They also performed a series of leak checks on their Sokol launch and entry suits.

Fossum had some time set aside to conduct experiments, including the Binary Colloidal Alloy Test experiment. The current version of the ongoing study, called BCAT-6, may help manufacturers design new leading edge materials with molecular precision at the nanoscale.

Fossum also joined Furukawa for Ultrasound 2 operations as part of the Integrated Cardiovascular experiment. That study measures the decrease in a crew member’s heart size during long duration microgravity missions.

Volkov replaced some filters that are part of the carbon dioxide scrubbing unit in the Russian segment.
