Superstorm Sandy and the importance of polar orbiting satellites in forecasting

On the 23rd of October, the 18th named storm of the 2012 Atlantic hurricane season, Tropical Storm Sandy, was born in the Central Caribbean. As is common for late-season storms in the Caribbean, Sandy moved northwards across Cuba. The official forecasts from the National Hurricane Center issued on October 23 called for Sandy to turn to the northeast after crossing Cuba, and head into the Central Atlantic. This forecast was based on the output from five of our top six computer models, which all predicted that an upper-level low pressure system in the Central Atlantic would be strong enough to pull Sandy northeastwards. However, the global weather forecast model run by the European Center for Medium-Range Weather Forecasts (ECMWF) showed a disturbing possibility: the upper-level low pressure system in the Central Atlantic would not be strong enough to turn Sandy to the northeast. The hurricane would instead get caught up in the flow associated with a trough of low pressure approaching the U.S. East Coast, and Sandy would get slung into New York or New Jersey on October 29. While the ECMWF model was the best performing model for tracking Atlantic hurricanes in both 2010 and 2011, and had done very well again so far in 2012, the American GFS model had outperformed the ECMWF model several times during the 2012 season. NHC elected to discount the ECMWF forecast for Sandy as an outlier, and went with the forecast from the GFS and other models. By October 25, it was clear that the ECMWF model had the right idea all along. More models were now showing the turn towards New York, and the official NHC forecast now called for Sandy to make landfall in New York or New Jersey on October 29. The ECMWF model's early forecast of a track for Sandy into the Northeast was critical for allowing additional time for residents to prepare for arrival of the devastating storm. So what enabled the ECMWF model to make such an excellent forecast for Sandy, six days in advance?


Figure 1. This image uses the model output from the ECMWF experiment, showing where Sandy was predicted to be located five-days out with the normal satellite data inputs into the model (left) and without any polar-orbiting satellite data (right). Both position and intensity forecasts were affected--Sandy stays out to sea without the polar-orbiting satellite data, and the closer isobar lines encircling the storm also imply a more organized and stronger system.

Polar satellite data: a key to ECMWF model success
The ECWMF has a very sophisticated technique called "4-D Var" for gathering all the current weather data over the Earth and putting the data on a 3-dimensional grid that is then used as the initial "reality" of the current weather for the model to use for its forecast. The old expression, "garbage in, garbage out" is a truism for weather forecast models. If you don't properly characterize the initial state of the atmosphere, the errors you start off with will grow and give a lower-quality forecast. Data from geostationary satellites, which sit continuously at one spot above the globe, are easy to assimilate, and all the models use this data. However, the ECMWF model's superior technique used to assimilate the initial data allows inclusion of data from a large number of polar-orbiting satellites, which the other models cannot do as well. Polar-orbiting satellites orbit Earth at an altitude of 540 miles twice per day, circling from pole to pole. Their data is difficult to use, since the it is only available twice per day at each spot on the Earth, and the time of availability is different for each location. According to an email I received from Jean-Noël Thépaut, the chief of the Data Division of the Research Department at the European Center for Medium-Range Weather Forecasts, the ECMWF model uses data from at least fourteen polar orbiting satellites: N-15, N-19, N-19, N-17 (ozone SBUV instrument only), Metop-A, AQUA, NPP (ATMS instrument only), AURA (ozone OMI data only), F-17, TRMM (TMI data), COSMIC, GRACE-A, TERRASAR, and the GPSRO data on top of METOP-GRAS. The data of most importance is the data collected in the infrared and microwave wavelengths, as well as atmospheric density data obtained via GPS radio occultation (as a polar orbiting satellite goes over the horizon, the GPS signals from the satellite get bent by Earth's atmosphere, with the amount of bending proportional to the density of the atmosphere. This GPS Radio Occultation data is gathered from eight polar orbiting satellites, and fed into both the ECMWF and GFS models.) You can find a nice summary of the impacts of polar orbiting satellite data on weather prediction models at this link.)


Figure 2. Forecast track error for four of our top models used to predict Hurricane Sandy, for their runs that began at 00Z October 25, 2012. By this time, the GFDL model had joined the ECMWF in predicting that Sandy would make landfall in Southern New Jersey in five days. The GFS and HWRF models made good 1 - 3 day forecasts, but failed to anticipate Sandy's north-northwestward turn towards the U.S. coast. Image credit: Morris Bender, NOAA/GFDL.

As originally reported by the Washington Post's Capital Weather Gang, then confirmed in a NOAA press release, a study done by ECMWF research scientist Tony McNally found that if the ECMWF model did not have all of the data from the fourteen polar orbiting satellites, the five-day forecast of the model for Hurricane Sandy would have shown Sandy missing the Northeast U.S. This brings up a concern, since the U.S. polar orbiting satellite program is behind schedule. As explained by Andrew Freedman of Climate Central, the program is plagued by mismanagement, billions in cost overruns, and technical development challenges. The next polar orbiting satellite is not scheduled to be launched until 2017, and one or more of the existing polar orbiting satellites are expected to fail before then. This will result in a degradation of our ability to observe and predict the weather, and may result in poorer forecasts for storms like Hurricane Sandy. Given that the ECMWF model used data from fourteen polar orbiting satellites, the failure of just one satellite may not have made a significant difference in its forecast for Sandy. But if we lose several of these key satellites by 2017, our hurricane forecasts in 2017 may be worse than they were in 2012. To figure out how to cope with the loss of satellite-derived data, NOAA is conducting a Gap Risk Study that seeks ideas from researchers and the public on how NOAA can preserve the quality of its weather model forecasts in the event of the failure of one or more polar orbiting satellites in the coming years.

Quoting Levi32:


Well it will probably be at the very least another week or week and a half. When this big ridge goes up into Alaska in 8-10 days, it will cause cold air to invade the west-central U.S., and this cold might have a chance to come into the eastern U.S. during the following week, but it's not guaranteed.

Thanks Levi.

Yes... thought it might be bogus too, then I did a little research.... High rises in Juneau too. And as I look at its innitial post of 7.7... that is what it innitially was rated. Some questions? And why I'd like a link or site to satellite??? Dark this time of year there... seems that anything with that kind of light  would show really well.
Quoting PlazaRed:

Some of the comments on the video say it is not Alaska and cite for reasons, the city and high buildings.
The lights I would guess are from transformers as they have that explosive signature of electrical discharges similar to lightning.
I would like to know where the video was taken and when, as it starts to reek of bogosity after a few viewings.
All the same, a quake of well over 7 on the pacific coast not long after we had on similar off the Mexico area.

Kitimat BC - It lasted for about 4 minutes
Wrangell Alaska - The shaking was more intense than we've experienced before. So much so that we stood under a doorway. It seemed to last quite a while. The house shook and dishes rattled in the cupboards.
Watson Lake, Yukon - ornaments on Christmas tree shaking and hanging plants swaying
Juneau - Shook the Christmas Tree pretty good.
Whitehorse Yukon - I was recording guitar and I started swaying ... and it wasn't to the beat of the music!
Vanderhoof B.C. - Not as intense as the last one a few months ago, but it woke me up out of bed. House made creaking sounds and the lights were swaying.
South Hazelton, BC - I was at the computer and felt a moving like I was on the water in a boat after a 'wake'... looked at the hanging plant which was swinging like a pendulum.
Juneau - felt movement, Christmas decor swinging, nothing fell from shelves

Yes, I also am not a conspiracy crazed person, but it is also hard to believe that this could be transformers. Why I wonder if satellite imagery got this and if there are any sites to see it? And I know they are not 'Northern lights'. This video also captures the fact that the initial thought that it was a 7.7 earthquake not later when it was downgraded to 7.5.

The idea of quartz causing discharges after distortion is very plausible in earthquakes, they have all sorts of hidden properties along with how certain species react before they happen.

From Wikipedia:

Earthquake lights are caused by an unknown mechanism. There are numerous theories as to how and why they occur.

One explanation involves intense electric fields created piezoelectrically by tectonic movements of rocks containing quartz.

Another possible explanation is local disruption of the Earth's magnetic field and/or ionosphere in the region of tectonic stress, resulting in the observed glow effects either from ionospheric radiative recombination at lower altitudes and greater atmospheric pressure or as aurora. However, the effect is clearly not pronounced or notably observed at all earthquake events and is yet to be directly experimentally verified

It looks like the GFS ensembles are coming around to the CMC track idea for the new Australian cyclone currently developing. Yesterday the GFS brought it straight south into the border between WA and NT while the CMC brought it much farther west. The last 3 runs of the GFS ensembles have shifted massively in the CMC's direction.

Thanks Skye, but I don't think NWS public radar pages have dual-pol display yet, at least that is what NWS Miami stated in their newsletter when they were upgraded.


Saw last night you were asking about UKMET data back on 10/25, tropicalatlantic has archive of model tracks, should use the EGRR (UKMET Office track).


Thanks I forgot EGRR was UKMET. That was the archive I used for CMC. Looks like 00Z UKMET was ~24hrs too slow on 10/25 but onto the left curve toward the NE. SO all the 4-D Var models caught onto to Sandy earlier.


Maybe it was hanging out at MLB NWS where I saw so much duel pol. I've tried to forget radar exists with my local being out of service so long. It's been close to a month so far maybe. I should get an update Tuesday when I'm there.

Not sure if it's still obtainable (it was suppose to be) through direct LDM data feed from the NWS. Much of the links I'm seeing in that direction is mostly dead. Might have some luck here if you are inclined to go that far with it.

It's Dr. Ricky Rood, a climate science professor and one of Weather Underground's featured bloggers. The forum attached to his blog is a place where science-minded individuals discuss the state of the climate, while others--perhaps temporarily unable to gather the attention they so desperately crave here in Dr. Masters' forum--stop by in hope of causing problems. It's full of polite and knowledgeable people, but those planning to do a silly denialist drive-by will quickly find themselves mercilessly ridiculed to the point that a cowardly retreat is their only option.

Here is the latest information by NCEP about the model site problems they are having but that will be resolved soon.


NCEP Model Analysis and Guidance (MAG) Website Status
January 4, 2013

Immediate Response to System Failure

On December 26, 2012, the MAG website experienced a major hardware failure at NOAA’s Web Operations Center (WOC). Twenty-four hours after the system crash, the WOC determined the operational MAG site to be unrecoverable. By the afternoon of December 27, NCEP Central Operations pulled together its resources and built a temporary site. The site initially hosted the GFS, NAM, and RAP graphical model output over the North American Region. Even though the functionality of the site differs considerably to the original site, customers will have access to the graphical model output with looping capabilities. To accommodate our customers who directly download the GIF images, the directory path of the images was maintained.

Near Term Solution


The remaining model output and observational data will be added in a phased approach as follows:

By January 7, 2013, NCEP will update the temporary MAG website to include the GEFS, SREF, NAM-HIRES, and additional regions for the GFS model.
By January 12, 2013, NCEP will provide the following model and observational data: NAEFS model output, Upperair, Skew-T, RTMA, and expanded regions for the GEFS, GFS and NAM model output.
By January 17, 2013, all remaining graphical model output and regions will be included on the temporary site. Data includes the Wave Watch III and HI-Resolution Window models.
Long Term Solution

NCEP Central Operations will re-architect the MAG to take advantage of our new Weather and Climate Operational Supercomputing System (WCOSS) scheduled to be fully operational later this year.

While the “look and feel” of the MAG site prior to the system failure will be preserved, the backend processing will be streamlined and moved to the new WCOSS allowing for more frequent site enhancements and provide the ability for customers to access experimental model runs. The new MAG architecture will eliminate the need for the complex Java, J2EE, JBOSS, and relational database components. Instead, the redesigned MAG will rely on internal process-driven html generator scripts.

The redesigned site is planned to be launched in May 2013.

yes and no, both are together but seperate depts with specific duties,once sandy became non tropical in nature..NHC handed it over to NWS..hence the problems...although..we stayed here all night huh posting the warnings and they DID state..hurricane or Above wind speeds...its semantics now..people pout because at the time they didnt listen to the warnings..hell we here posted on it for days before

Again, the NHC didn't "hand it over to the NWS" - the NHC is the NWS. Sandy was handled by the National Weather Service all of this time.

This goes with post 434..had a moment to slum a little deeper in the GRACE files directory. Where in 434 I left the animated land mass map. This goes with bit about separating the GRACE land from ocean mass measurements since water & land use different functions to assimilate the data correctly into the ECMWF & such.. Without further ado mind blowing ocean mass measurements for the last near 10 years..

What the National Hurricane Center (NHC), working with other NWS offices, chose to do was controversial within the meteorological community, and now it is likely to reverberate throughout the insurance industry.

The Hurricane Center chose not to issue any hurricane watches or warnings beyond North Carolina, even though many areas would see hurricane-force wind gusts. Instead, NHC allowed local NWS offices to issue an array of warnings ranging from high-wind warnings to coastal-flood warnings. Rick Knabb, the director of the NHC, told reporters that the decision was made in order to minimize confusion in the event that Sandy was reclassified as a post-tropical cyclone before making landfall, which would have required that all hurricane warnings be canceled, and other warnings to be issued instead.

“By using non-tropical warnings in these areas from the start, we avoid or minimize the significant confusion that could occur if the warning suite changed from tropical to non-tropical in the middle of the event,” NHC said in a statement.
