Flying into a record Nor'easter

Blizzard of 2006: a Category 3 storm
Before we talk about flying into one of the most severe Nor'easters of all time, lets mention the Blizzard of 2006 once more. NOAA has classified the storm as a Category 3 storm on the new NESIS storm scale, two notches down from the most severe kind of blizzard. While the Blizzard of 2006 set snowfall records in New York City and Hartford, the overall size of the area affected was lower than in mega-blizzards like the Superstorm of 1993 that earned Category 5 rankings.

Tale of a record-breaking Nor'easter
If you're wondering what the NOAA Hurricane Hunters do in the winter when they're not flying hurricanes, the answer is simple--they're somewhere else where the weather is bad! During my four years with the Hurricane Hunters, I regularly spent my summers in the tropics and winters in the Arctic. I logged over 25 missions into intense winter storms as part of field projects based in Norway, Alaska, and the U.S. During the winter of 1989, we were stationed at Brunswick, Maine for three months as part of the Experiment on Rapidly Intensifying Cyclones over the Atlantic (ERICA). This project utilized the two NOAA P-3 research aircraft and the another aircraft with Doppler radar, the NCAR Electra, to provide an unparalleled data set documenting the life cycle of ten North Atlantic extratropical cyclones. During one of these flights, we caught the central Atlantic's most intense winter storm on record.


Figure 1. The ground crew de-ices NOAA's P-3 winter storm hunter aircraft in preparation for chasing a Nor'easter that buried the Brunswick, Maine operations base with a foot of snow.

On January 3, 1989, a strong extratropical cyclone moved off the coast of North Carolina, and pulled a large mass of Arctic air over the ocean behind it. As the cyclone crossed the warm waters of the Gulf Stream, where water temperatures were over 70 degrees, the storm "bombed". It's central pressure fell 66 mb in 18 hours to an astounding 936 mb--a pressure typical of a Category 3 or 4 hurricane! Post-analysis of the data suggested that the pressure fell even further, to 928 mb. This was the lowest pressure ever observed in an Atlantic extratropical cyclone south of 40 degrees latitude in the 20th century. But since the storm never affected land, few people outside of the research community have ever heard of it, and it doesn't even get a ranking on the NESIS scale.

I was tasked to be flight director on the daytime January 4 mission into this storm, dubbed Intensive Operating Period 4 (IOP 4). As I drove to work that morning on treacherously icy roads, I reflected on the fact that this part of my day would probably the most dangerous part--not this afternoon's flight at low altitude into a hurricane-strength winter storm! Although I had had a few rough flights on my 20 or so missions into winter storms, none had ever compared to flying into a hurricane. There isn't much deep convection in a winter storm out over the ocean, since the water is usually too cold to support intense thunderstorms. Deep convection creates sudden updraft and downdrafts--the kind of turbulence that is a bane to aircraft.


Figure 2.Visible satellite image of the ERICA IOP 4 January 4, 1989 cyclone--the most intense winter cyclone ever measured in the central Atlantic.

At our pre-flight briefing, though, I began to wonder if maybe the most dangerous part of the day lay ahead! The flight crew from the just-returned midnight flight reported that the storm was entering a rapid deepening cycle. They encountered intense lightning and moderate turbulence in some of the rain bands. The morning satellite imagery confirmed that we were dealing with a true monster--none of us could ever remember seeing such huge storm over the Atlantic.

We took off and droned southeastwards towards the storm. As we neared the storm, we noticed that it's far-flung rain and snow bands painted our radar displays with bright patches of color we were unused to seeing in a winter storm. The nose radar, which had a special algorithm to plot turbulent areas in a bright purple color, was showing the the first purple I had ever seen in an extratropical cyclone. As we approached the north side, we descended to 350 meters (1150 feet) in altitude and prepared to penetrate the center of the storm.

"SET CONDITION ONE!" crackled pilot Ron Phillipsborn's voice over the aircraft's loudspeakers and intercom. When announced by the Aircraft Commander, Condition One requires all hands to return to their seats and prepare for turbulence. Throughout the airplane, the crew stashed away flight bags, clip boards, and other loose items that could turn into dangerous missiles in severe turbulence, and buckled up their heavy-duty seat belts.

We plowed through an intense band of snow and rain that rocked the aircraft. The winds jumped to 60 mph. Glimpses of the ocean below revealed a maelstrom of white-capped, wind-whipped 20-foot waves.

"Whoa, that was a pretty intense band!" I remarked over the intercom as we emerged from the band and the turbulence subsided. "Ron, are you happy at 1200 feet?" I asked the pilot, who had just joined the Hurricane Hunters, and had yet to fly a mission into a hurricane.

"No problem!" Ron replied. He held us on course for a penetration straight through the center of the cyclone. When we reached the calm center, there was no spectacular view like one sees in a hurricane--the center of this storm was surrounded by clouds. But there was plenty of excitement among the science team, headed by Dr. Mel Shapiro of NOAA.

"Did you see that pressure?" Mel exclaimed. "941 millibars! And what a temperature jump--we've got an incredible amount of warm air at the core of this storm. And check out out those SST's--70 degree water. No wonder we're seeing such impressive convection!" Indeed, the radars showed an impressive amount of intense echoes on all sides of us.

We continued southward, then cut across the cold front. As we crossed the cold front, we hit a remarkable updraft of 7.5 m/s (17 mph). All around us, huge cumulonimbus clouds pushed upwards by the tremendous lift along the front lit up with impressive lightning displays. As we crashed through the front, the surface winds picked up to 100 mph, and some hard, jolting bumps of turbulence rocked the airplane. This was like flying through a Category 2 hurricane! An awesome parade of 35-foot high waves whipped into a green-white froth rolled beneath us.

"Hey Ron!" I exclaimed as we emerged into the clear beyond the cold front. "How does it feel to fly through a Category 2 hurricane?"

"No problem!" Ron replied. He was handling the turbulence like a veteran.

We turned back towards the center again. It was time to take another reading of the storm's central pressure to see how much it had deepened. As we approached the center, once more we encountered bands of showers with strong turbulence. This storm was getting to be a bit of a pain! Finally, we punched into the center again.

"Whoo-eee!" I exclaimed, as winds went calm and the lowest pressure flashed onto the monitors. "936 millibars! That's got to be a record!"

"Fantastic!" agreed Mel. "Let's go check out the triple point now." The triple point is where an extratropical cyclone's cold front, warm front, and occluded front all meet, and is often the most turbulent portion of the storm.

We turned east towards the triple point, and our ride steadily grew rougher and rougher. Frequent intense bands of showers rocked the aircraft, and the ominous purple color of turbulence grew more and more concentrated on the nose radar. Ron did his best to sneak through gaps in the clouds to avoid the worst of the turbulence, but it was still a rough, uncomfortable ride. Finally, the radar showed no more soft spots--we were surrounded on three sides by thunderstorm cells showing some very nasty-looking purple radar echoes.

"Uh, Jeff, what do you think we should do here?" Ron asked, sounding uneasy about the mass of purple directly in front of us.

I took a moment to study the radar display before replying. "Let's get out of here! U-turn, back the way we came!"

"You got it!" agreed Ron happily, immediately banking the the big plane over into a 180-degree turn.

"Ron, Jeff, I think its time to do some high-altitude work!" agreed Mel. We were more than happy to oblige, and climbed to 18,000 feet to study the upper-level structure of the cyclone for a while.

Postscript
The January 4, 1989 flight into the IOP 4 storm marked the only flight I'd ever been on where we performed a U-turn to escape severe turbulence. Despite not directly measuring the most interesting part of the storm, we were able to capture the best data set ever of an extratropical cyclone tapping the warm waters of the Gulf Stream to become a hybrid warm-core system.

My next update will be on Friday, when I'll probably talk about hurricanes and global warming again.

Arcturus,again thanks for posting Dr.Hansen's article. I read it carefully. In the past, I considered him a bit alarmist, but one has to take these observations seroiusly. I was very upset that the Bush administration tried to censor him. We need to carefully consider what everyone in the scientific community has to say. A good starting point in the U.S. would be to improve our fuel-efficiency standards for vehicles significantly. The automakers took advantage of loopholes in the current standards to create the SUV / monster truck culture we have now. We can't all ride bicycles everywhere, but we can have more fuel efficiency without drastically disrupting our economy. On the other hand, the U.S. shouldn't be expected to make all the sacrifices while China, India, etc. get a free ride to pollute all they want. Could there be a connection between the acceleration of the warming trend in the past 10 years and the steep increase in fossil fuel consumption in so-called "developing" countries with booming economies such as China?

Hey everyone,

Has anyone seen the article from an Insurance website that I stumbled upon a short time ago, highlighting Max Mayfields comments regarding the upcoming 2006 hurricane season?

If not, I posted the article in its entirety on my latest blog for more convenience, and it is a very interesting read to say the least.

In it, he suggests 2006 could be more active than 2005.

I hope everyone has a goodnight and I will hopefully talk you all again soon.:)

Your friend,
Tony

928 mb in an extratropical cyclone??? That's incredible! That is more typical of a hurricane with winds of around 150 mph (strong Category 4)...

there isn't much moisture in the storm now, lightning10, but it is passing over the ocean. Most of the precip will be showery and will come from instability, i think. The moisture may be pulled in but if it is, it will only be in the initial front and the post-frontal showers would still be really cold.

Average snow level is probably closer to 6000 feet than 7000 but it has been rising in the last few decades, if you ask any of the old timers. Not good for the ponderosas in the high country but they have much bigger problems to face due to fire suppression and bark beetles.

They said altadena right near where i live could get a dusting.. i am at about 900 feet so probably won't get any here. However, this weekend i will be in Mammoth. I already know there will be snow there.. but i am hoping there will be a dusting in the desert as i drive up the 14/395.

Hi friends. I had an interesting thought. As you know there is a very cold system for western standerds coming in for the area all along the west coast. A cut off low bringing down some very cold air. Some computer modles are saying areas that rarely if ever get snow might get a light dusting to a few inches. There saying the snow level even in Southern California is going to be 3,500 foot. (its probaly on average around 7,000 feet)

However as the storm is moving down the coast it is drying out quickly.

There is some mositure to the south it might pick up. That will reinstate the moistre it has. If it doesnt then from what I understand we would get nothing more then a few dropes of sprinkels and a some light snow flurrys.

here is an immage of the ocean. You can see the low and the mosisture toward the south

My question would be if it did pick up that moisture from the south wouldnt the snow level rise very quickly? Mybe 5-6,000 feet like an average storm?

I just had some of the scariest 20 minutes of my life. More details later.

Then a little later:

I had a supercell with a confirmed funnel cloud moving right at me at 65 MPH, right when my sister was on her way home from school, with tons of sirens going off, with my town specifically mentioned in the warning, and with a really nasty sky; and it turned east a skirted just south of me about 4-5 minutes before the tornadic part was scheduled to hit. It was scary. We still had the bad supercell core pass right over us.

Those were posted just a few minutes ago from TornadoTy, in Indiana.

Kept meaning to join for $10 but, kept forgetting. Well this article & the reminder of the Hugo story made me finally go do it!!!!!
THANX FOR THE AWESOME WEBSITE DR. MASTERS!!!!!!!!!!!!!!!!!

BTW... thanx also to everyone who has ever read & posted in my global warming blog. I think we all see that this issue is almost as touchy as religion & politics (which got drawn into the debateLOL)
Everyone should really pay the $10 cause I think this site with all the hurricane focus is gonna be invaluable in the coming seasons ahead!!!

We hit 20 - 25 mph downdrafts in Hurricane Hugo and dropped 700 feet, but that is not a realistic measure of what a downdraft will do to a P-3, since we had an engine on fire and the pilot had lost control of the aircraft.


Wow and I thought riding out Charley in the closet was a life altering experience. Thanks Dr. Masters for the great post. When you live somewhere like I do, Florida, we are obsessed with protecting our homes and getting ready for the hurricane. What an amazing job the hurricane hunters do. I will definitely be remembering this post when I read the hurricane watch and warnings this year.

Dr. Masters,

OIC (ie Doppler radar, and by dropping probes on parchutes (dropsondes) ), but that does bring up a interesting question. In your expert opinion which nets better data Doppler radar and dropsondes or direct measurements.

Also do you think at some point in the future techonlogy will made the Hurricane Hunters obsolete, or do you think the inherent nature of weather will make it impossible to be reduced to a alogrithm?

You can still get good data from an area you can't fly into by probing it with Doppler radar, and by dropping probes on parchutes (dropsondes) into the region of interest. We did both of those things on this flight.

Dr. Master,

First of all YOU DA MAN. Between this and and the Hugo flight proves that to be a Hurricane Hunter you got to have some serious stones.

But one part has me a bit miffed this quote:

"..The January 4, 1989 flight into the IOP 4 storm marked the only flight I'd ever been on where we performed a U-turn to escape severe turbulence. Despite not directly measuring the most interesting part of the storm, we were able to capture the best data set ever of an extratropical cyclone tapping the warm waters of the Gulf Stream to become a hybrid warm-core system..."

How where you able to get the best data if you turned away from the most interesting part of the storm aka the "triple point"?

Michalp, the tunnels for weather modification are far far away. This article you speak about is mearly a horizontal turbine, working with the flow, similar to hydro-electric power. Simple concept here, as for trying to harvest this energy with water moving upwards, totally different animal.

Dr. Masters, I was thinking about your Hugo story while reading this, and hoping that it wouldn't turn into a repeat. I was getting a little uneasy reading about the pilot's enthusiasm about flying so low through all that turbulence. The u-turn sounded like a good idea!

Since that stormed 'bombed' so quickly and deeply, did a hurricane form inside it like it did with the Perfect Storm that was discussed yesterday?

Hi,Oeneus - it's snowing pretty good here in Thornton now and starting to stick. The radar shows a decent band of snow setting up from Boulder right up toward Greeley. Maybe we can get 2-4" out of this anyway.

We hit 20 - 25 mph downdrafts in Hurricane Hugo and dropped 700 feet, but that is not a realistic measure of what a downdraft will do to a P-3, since we had an engine on fire and the pilot had lost control of the aircraft.

Other than Hugo, the strongest downdrafts I remember hitting were in Hurricane Gilbert when it was a Cat 5 with 175 mph winds, where we saw downdrafts of about 7 m/s (16 mph). These were rather broad, and carried our plane downward about 400 feet (we were flying at 10,000 feet). We hit updrafts that were twice as strong, and carried us upwards about 900-1000 feet.

In the old days, before modern Inertial Navigation Equipment (INEs) were developed, the hurricane hunters flew beneath the clouds so they could navigate to the storm's center by watching the wind direction on the water below. This meant flying at altiudes of 500 feet or so, and it is not hard to imagine why the sole hurricane hunter plane lost in the Atlantic (Hurricane Janet in 1955) went down--Janet was a Category 5 hurricane, and probably had downdrafts of 10-20 mph. This would have been enough to push the old Super Constellation they flew into the water.

Dr.Masters - I really enjoyed your post. If one of these storms ever "bombed" that low close enough to the coast it would be an awesome blizzard! But the warmest waters are a little too far away. I'm all for giving both global warming and the tunnels a rest for a while - thanks, everyone! We're hoping for some snow here in Denver tonight, but don't know if we'll get very much. Looks better to the north of us.

Great post Dr Masters! This past summer comming back from the east coast, my plain experience some scary turbulence. Turned out we were flying over one of the most intense thunderstorms in the midwest that summer. Actually flying into these regularily would not be something I would really want to do, furthering my respect for someone like you who does it frequently. When you say you flying through turbulence, how far can the plain drop in these down drafts when you fly through them? Nice work.
