Haiyan's True Intensity and Death Toll Still Unknown

By: Dr. Jeff Masters, 5:10 PM GMT on November 15, 2013

A full week after one of the strongest tropical cyclones in world history devastated the Philippines, the full extent of the death and destruction wrought by Super Typhoon Haiyan is still not fully known, nor do we have actual ground measurements of the storm's peak winds and lowest pressure. The Philippines ‪National Disaster Risk Reduction and Management Council‬ estimates 3432 people were killed, and the U.N. puts this number at 4,460. This makes Haiyan the 2nd deadliest Philippines tropical cyclone in history, behind Tropical Storm Thelma of 1991, which killed 5081 - 8165 people. Damage is estimated at $12 - $15 billion, or about 5% of the Philippines' GDP.


Figure 1. Infrared VIIRS image of the eye of Haiyan taken at 16:19 UTC November 7, 2013. At the time, Haiyan was at peak strength with 195 mph sustained winds. Image credit: NOAA/CIRA.

What was Haiyan's lowest pressure?
The Japan Meteorological Agency (JMA) estimated that Haiyan's central pressure was 895 mb at landfall, which would make it the 12th strongest tropical cyclone in world history (by pressure.) We now have pressure measurements from Haiyan's second landfall in Tacloban, where a group of storm chasers deployed two high-quality Kestrel pressure instruments in the Hotel Alejandro, in the heart of the Downtown district (11.2414N 125.0036E.) This location was about eighteen miles north of the center of the eye, and did not receive the typhoon's strongest winds, which probably occurred about two miles to the south, judging by the zoomed-in radar image from landfall (Figure 3.) Josh Morgerman of iCyclone.com was kind enough to send me plots of the data recorded from their instruments. Device 1 measured a minimum pressure of 960.8 mb at 7:12 am, and their Device 2 measured 960.3 mb at 7:20 am. Josh talked to a source at the Tacloban Airport, located about 1 mile farther to the south, who said that the airport measured 955.6 mb at 7:15 am, before power was lost. These readings suggest that Haiyan had a pressure gradient of about 4 mb per mile. If we assume the airport was 17 miles north of the center of the eye, and there was a 4 mb/mile pressure gradient, Haiyan could have had an 888 mb central pressure. An email I received from NHC hurricane specialist Dr. Jack Beven documented several cases of Category 5 tropical cyclones with extreme pressure gradients:

Hurricane Andrew, 1992 (South Florida): 60 mb in 14 miles (4.3 mb/mile)
Hurricane Wilma, 2005 (in Caribbean): 94 mb in 14 miles (6.7 mb/mile)
Super Typhoon Megi, 2010 (east of Philippines): 60 mb in 14 miles (4.6 mb/mile)
September 1933 hurricane (ship measurement): 45 mb in 6 miles (7.5 mb/mile)
Hurricane Felix, 2007 (in Caribbean): 63 mb in 14 miles (4.5 mb/mile)

So, it is certainly possible that Haiyan had a pressure below 900 mb, but we will probably never know for certain.


Figure 2. Pressure observed in downtown Tacloban during the passage of Super Typhoon Haiyan on November 8, 2013 by Josh Morgerman of iCyclone.com. This sensor bottomed out at 960.3 mb at 7:20 am, at a location a few miles north of the northern edge of the eye. If we look at the Tacloban airport pressure readings in the last 3 hours they sent data on November 8, the readings were 1001.1 mb, 1000.9 mb, and 997.3 mb at 12 am, 1 am, and 2 am, respectively. The iCyclone instrument recorded 1002 mb, 1000 mb, and 998 mb at those times, so the two instruments agreed to within 1 mb.


Figure 3. Radar image of Super Typhoon Haiyan over Tacloban, on November 8, 2013. Tacloban was in the north (strongest) portion of Haiyan's eyewall, at a time when the typhoon's top sustained winds over water were estimated at 185 mph. Image credit: http://climatex.ph.

How strong were Haiyan's winds at initial landfall in Guiuan?
Haiyan's strongest winds occurred on the south shore of Samar Island and the city of Guiuan (population 47,000), where the super typhoon initially made landfall with 1-minute average winds estimated at 195 mph. This estimate came from the Joint Typhoon Warning Center (JTWC), and was based on satellite measurements. We have no ground level or hurricane hunter measurements to verify this estimate. The Japan Meteorological Agency (JMA), which uses their own techniques to estimate typhoon strength via satellite imagery, put Haiyan's peak strength at 125 knots (145 mph), using a 10-minute averaging time for wind speeds. The averaging time used by JTWC and NHC is 1-minute, resulting in a higher wind estimate than the 10-minute average winds used by JMA and PAGASA in their advisories. To convert from 10-minute averaged winds to 1-minute average, one conversion factor that is commonly used is to multiply by 1.14--though lower conversion factors are sometimes used. JMA satellite strength estimates are consistently much lower than those from JTWC for high-end Category 5 strength typhoons; JTWC estimates are the ones most commonly used by the hurricane research community. A searchable database going back to 1976 of the JMA typhoon information available at Digital Typhoon reveals that Haiyan is tied for second place as the strongest typhoon that JMA has rated, and was the strongest landfalling typhoon, when measured by wind speed. The only typhoon they rated as stronger was Super Typhoon Tip of 1979, but that storm weakened to Category 1 strength before making landfall in Japan.


Figure 4. The 400-year-old Church of the Immaculate Conception (left) collapsed in Guiuan, Philippines, during Super Typhoon Haiyan. Image credit: J.B. Baylon and http://chuvaness.com/.

Typhoon and hurricane maximum wind speed estimates are only valid for over water exposure, and winds over land are typically reduced by about 15%, due to friction. This would put Haiyan's winds at 165 mph over land areas on the south shore of Samar Island. This is equivalent to a high end EF-3 tornado. Forty minutes before landfall, the airport in Guiuan reported sustained 10-minute average winds of 96 mph, with a pressure of 977 mb, before contact was lost. damage photos of Guiuan show at least EF-2 scale damage (111 - 135 mph winds): Roofs torn off well-constructed houses; foundations of frame homes shifted; mobile homes completely destroyed; large trees snapped or uprooted; light-object missiles generated; cars lifted off ground. The mayor of the city had his car lifted off the ground and slammed into a building, which is consistent with at least EF-2 damage. There is possible EF-3 damage (136-165 mph winds) in the Guiuan damage photos, with the 400-year-old stone Church of the Immaculate Conception collapsed, and a bus toppled. EF-3 damage is defined as: Entire stories of well-constructed houses destroyed; severe damage to large buildings such as shopping malls; trains overturned; trees debarked; heavy cars lifted off the ground and thrown; structures with weak foundations blown away some distance. A detailed damage survey would be need to determine if EF-3 winds really did occur in Guiuan.

“Tipping Points”, the landmark 6-part climate change TV series that began airing in October on The Weather Channel, airs for the fifth time on Saturday night, November 16, at 9 pm EDT. The new episode, "The Greenland Ice-sheet Melt", goes on an expedition to the remote Inuit village of Qaanaaq to explore the rate Greenland Ice sheet melt and its effects on global ocean circulation. I make a short appearance 8 minutes into the episode to report on how much ice Greenland has lost in the past decade. The series is hosted by polar explorer and climate journalist Bernice Notenboom, the first woman to perform the remarkable triple feat of climbing Mt. Everest and walking to the North and South Poles. In each episode, Notenboom heads off to a far corner of the world to find scientists in the field undertaking vital climate research to try to understand how the climate system is changing and how long we have to make significant changes before we reach a tipping point--a point of no return when our climate system will be changed irreversibly.

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

PUBLIC SEVERE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0249 AM CST SUN NOV 17 2013

...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE MID-MISSISSIPPI
AND OHIO VALLEYS INTO MICHIGAN TODAY THROUGH EARLY TONIGHT...

The NWS Storm Prediction Center in Norman, Oklahoma is forecasting
the development of a few strong, long-track tornadoes over parts of
the Mid-Mississippi and Ohio Valleys into Michigan today through
early tonight.

The areas most likely to experience this activity include:

Illinois
Indiana
Northern and Western Kentucky
Lower Michigan
Ohio
Southeast Wisconsin

Surrounding this greatest risk region, severe thunderstorms will
also be possible from parts of Wisconsin, Iowa, Missouri, Arkansas,
Mississippi, Alabama, and Tennessee northeastward across much of the
Appalachians to the lower Great Lakes.

A potent jet stream disturbance with wind speeds in excess of 120
knots will sweep east across the central Plains today and across the
Ohio Valley and northern half of the Appalachians tonight. As this
occurs, a surface low now over the mid-Mississippi Valley will
rapidly intensify and accelerate northeastward, reaching northern
Michigan early tonight and western Quebec Monday morning.

East of the low, increasingly warm and humid air at the surface will
spread north across the Tennessee and Ohio Valleys, contributing to
very unstable conditions over a large part of the east central
United States. Coupled with daytime heating and ascent provided the
jet stream impulse, the environment will become very favorable for
severe thunderstorms --- especially along and ahead of fast-moving
cold front trailing southward from the low into the mid-Mississippi
and Ohio Valleys.

Given the degree of thermodynamic instability, and the strength and
character of the winds through the depth of the atmosphere, many of
the storms will become supercells. Some of these will be capable of
producing strong tornadoes --- in addition to large hail and swaths
of damaging surface winds.

The storms are expected to consolidate into one or two extensive
lines later today into tonight --- extending the threat for damaging
winds and isolated tornadoes eastward into the Appalachians by early
Monday.

State and local emergency managers are monitoring this potentially
very dangerous situation. Those in the threatened area are urged to
review severe weather safety rules and to listen to radio,
television, and NOAA Weather Radio for possible watches, warnings,
and statements later today.

Digest of Rules Main

Emergencies and Unfair Acts

Emergencies -- Policy

The National Football League requires all League personnel, including game officials, League office employees, players, coaches, and other club employees to use best effort to see that each game -- preseason, regular season, and postseason -- is played to its conclusion.

The League recognizes, however, that emergencies may arise that make a game’s completion impossible or inadvisable. Such circumstances may include, but are not limited to, severely inclement weather, natural or manmade disaster, power failure, and spectator interference.

Games should be suspended, cancelled, postponed, or terminated when circumstances exist such that commencement or continuation of play would pose a threat to the safety of participants or spectators.

Authority of Commissioner’s Office

Authority to cancel, postpone, or terminate games is vested only in the Commissioner and the League President (other League office representatives and referees may suspend play temporarily; see point No. 3 under this section and point No. 1 under "Authority of Referee" below). The following definitions apply:

• Cancel . To cancel a game is to nullify it either before or after it begins and to make no provision for rescheduling it or for including its score or other performance statistics in League records.

• Postpone . To postpone a game is (a) to defer its starting time to a later date, or (b) to suspend it after play has begun and to make provision to resume at a later date with all scores and other performance statistics up to the point of postponement added to those achieved in the resumed portion of the game.

• Terminate . To terminate a game is to end it short of a full 60 minutes of play, to record it officially as a completed game, and to make no provision to resume it at a later date. The Commissioner or League President may terminate a game in an emergency if, in his opinion, it is reasonable to project that its resumption (a) would not change its ultimate result or (b) would not adversely affect any other interteam competitive issue.

• Forfeit . The Commissioner, (except in cases of disciplinary action; see last section on "Removing Team from Field"), League President, and their representatives, including referees, are not authorized unilaterally to declare forfeits. A forfeit occurs only when a game is not played because of the failure or refusal of one team to participate. In that event, the other team, if ready and willing to play, is the winner by a score of 2-0.

If an emergency arises that may require cancellation, postponement, or termination (see above), the highest ranking representative from the Commissioner’s office working the game in a "control" capacity will consult with the Commissioner, League President, or game-day duty officer designated by the League (by telephone, if that person is not in attendance) concerning such decision. If circumstances warrant, the League representative should also attempt to consult with the weather bureau and with appropriate security personnel of the League, club, stadium, and local authorities. If no representative from the Commissioner’s office is working the game in a "control" capacity, the referee will be in charge (see "Authority of Referee" below).
In circumstances where safety is of immediate concern, the Commissioner’s-office representative may, after consulting with the referee, authorize a temporary suspension in play and, if warranted, removal of the participants from the playing field.

The representative should be mindful of the safety of spectators, players, game officials, nonplayer personnel in the bench areas, and other field-level personnel such as photographers and cheerleaders.
If possible, the League-office representative should consult with authorized representatives of the two participating clubs before any decision involving cancellation, postponement, or termination is made by the Commissioner or League President.

If the Commissioner or League President decides to cancel, postpone, or terminate a game, his representative at the game or the game-day duty officer will then determine the method(s) for announcing such decision, e.g., by public-address announcement over referee’s wireless microphone, by public-address announcement by home club, or by communication to radio, television, and other news media.

Authority of Referee

If a referee determines that an emergency warrants immediate removal of participants from the playing field for safety reasons, he may do so on his own authority. If, however, circumstances allow him the time, he must reach the highest ranking full-time League office representative working at the game in a "control" capacity or the game-day duty officer designated by the League (by telephone, if that person is not in attendance) and discuss the actual or potential emergency with such representative or duty officer.
That representative or duty officer then will make the final decision on removal of participants from the field or obtain a decision from the Commissioner or League President.

If a referee removes participants from the playing field under No. 1 above, he may order them to their respective bench areas or to their locker rooms, whichever is appropriate in the circumstances.
After appropriate consultation under No. 1 above, the referee must advise the two participating head coaches of the nature of the emergency and the action contemplated (if the decision has not yet been reached) or of the final decision.
The referee must not, before a decision is reached, make an announcement on his microphone concerning the possibility of a cancellation, postponement, or termination unless instructed to do so by an appropriate representative of the Commissioner’s office.
The referee must not discuss a forfeit with head coaches or club personnel and must not use that term over the referee’s microphone (see definition of forfeit under No. 1 of "Authority of Commissioner’s Office" above).
The referee must not assess an unsportsmanlike-conduct penalty on the home team for actions of fans that cause or contribute to an emergency.
The referee should be mindful of the safety of not only players and officials, but also of the spectators and other nonparticipants.
If an emergency involves spectator interference (for example, nonparticipants on the field or thrown objects), the referee immediately should contact the appropriate club or League representative for additional security assistance, including, if applicable, involvement of the League’s security representative(s) assigned to the game.
The referee may order the resumption of play when he deems conditions safe for all concerned and, if circumstances warrant, after consultation with appropriate representatives of the Commissioner’s office.
Under no circumstances is the referee authorized to cancel, postpone, terminate, or declare forfeiture of a game unilaterally.
Procedures for Starting and Resuming Games
Subject to the points of authority listed above, League personnel and referees will be guided by the following procedures for starting and resuming games that are affected by emergencies.
If, because of an emergency, a regular-season or postseason game is not started at its scheduled time and cannot be played at any later time that same day, the game nevertheless must be played on a subsequent date to be determined by the Commissioner.

If an emergency threatens to occur during the playing of a game (for example, an incoming tropical storm), the starting time of the game will not be moved to an earlier time unless there is clearly sufficient time to make an orderly change.

All games that are suspended temporarily and resumed on the same day, and all suspended games that are postponed to a later date, will be resumed at the point of suspension. On suspension, the referee will call timeout and make a record of the following: team possessing the ball, direction in which its offense was headed, position of the ball on the field, down, distance, period, time remaining in the period, and any other pertinent information required for an orderly and equitable resumption of play.

For regular-season postponements, the Commissioner will make every effort to set the game for no later than two days after its originally scheduled date and at the same site. If unable to schedule at the same site, he will select an appropriate alternative site. If it is impossible to schedule the game within two days after its original date, the Commissioner will attempt to schedule it on the Tuesday of the next calendar week. The Commissioner will keep in mind the potential for competitive inequities if one or both of the involved clubs has already been scheduled for a game close to the Tuesday of that week (for example, a Thursday game).

For postseason postponements, the Commissioner will make every effort to set the game as soon as possible after its originally scheduled date and at the same site. If unable to schedule at the same site, he will select an appropriate alternative site.

Whenever postponement is attributable to negligence by a club, the negligent club is responsible for all home club costs and expenses, including, subject to approval by the Commissioner, gate receipts and television-contract income. [See Section 19.11 (C) of the NFL Constitution and Bylaws.]

Each home club is strictly responsible for having the playing surface of its stadium well maintained and suitable for NFL play.
