Tropical Cyclone-Related Anniversaries [Five-year Intervals Only]

#1 Postby Imran_doomhaMwx » Sun Nov 19, 2017 11:37 am

Let me start with:

November 19, 1977 (40yrs ago) -- A powerful unnamed Category 4 Cyclone struck the Indian state of Andhra Pradesh at this time of the year 40 years ago, later dubbed as the "1977 Andhra Pradesh Cyclone" or the "Diviseema Cyclone".

The cyclone claimed the lives of 10,000-15,000 people as reported by the government, including the thousands of deaths that occurred in Diviseema island after it was inundated by a 20ft(6m) high storm surge. However, another source claimed that the true number of people killed was at least 50,000 and that the government intentionally underreported the death toll.

November 21, 1992 (25yrs ago) -- 25 years ago, Category 5 SuperTyphoon "Gay" (not to be confused with 1989's TC Gay) reached peak intensity over the open waters of the NW Pacific, with max sustained winds of 295kph as estimated by JTWC, and a min central pressure of 900mb by JMA.
Two other Tropical Cyclones, which were both already weakening at that time, can also be seen on this satellite image. Namely, "Hunt" to the NW of Gay, and "Forrest" over the northern Bay of Bengal (the latter also originated from the NW Pacific basin).

(IR satellite image from Digital-Typhoon -- 11/21/1992 00Z)

1992's STY Gay is notable as it is one of those TCs suspected to be stronger/more intense than 1979's STY "Tip". However, unlike Tip which had a recon aircraft take actual measurements of its strength, Gay's were only estimates, thus making it hard/impossible to confirm if it was indeed stronger than Tip.
Gay affected the Marshall islands as a typhoon earlier in its existence, and passed over Guam about two days after reaching peak intensity, but still as a strong Typhoon. It then recurved and also affected parts of Japan as an ExtraTropical system.

As a matter of fact, it's dvorak reached 8.7 on the scale. Something Tip was unable to do. Yeah estimates but it's presentation is much more impressive.

it reached 8.7 on a PROTOTYPE auto Dvorak technique, which has since been refined. No way can one make an apples to apples comparison to today's techniques

November 25, 1987 (30 years ago) -- Tropical Cyclone "Nina" (locally named "Sisang" in the Philippines) slammed the Philippines' Bicol region as a Category 5 SuperTyphoon. STY Nina caused widespread damage to much of the northern Philippines, and killed around 800 people in the country.

The strongest typhoon of the season and right after recon ended...I know social media wasn't active back then but i hate to think what if recon ended right in the middle of the 2018 season after reports of extraordinarily low pressures and high winds typhoons suddenly became weaker due to the absence of recon and now relied on satellite. Global cooling? :lol: The meteorological community would be very sad.

What a beautiful yet monstrous typhoon at landfall! Almost looks like Mitch at peak strength in the other side of the world. What a beast! Imagine the conditions at landfall there, must have been truly catastrophic. :double:

A minimum pressure of 909.5 hPa was recorded in the Philippines during the eye passage of Typhoon Nina, which would suggest a peak intensity of approximately 900 hPa. AFAIK it should also be the lowest pressure recorded in the Philippines (Typhoon Haiyan was 910 hPa). Pressure wise, Betty would be a stronger storm, and perhaps for wind speed as well because Betty was a smaller system. FYI intensity estimates from JTWC for Betty and Nina were 140 and 145 kt, respectively, and the former was probably an underestimation.

why's JMA not updating their best track? 930 mb peak? Smhhh..

Betty was reanalyzed by Knaff as a 170 knot system at peak, JTWC clearly underestimated it and it's also highly probable that it was a cat 5 when it crossed Samar.

Added info : a barometric pressure of 911mb was recorded in Fuga Islands in Cagayan on August of 1922 - that's according to records compiled by Selga

December 3rd, 2012 [five years ago]: Super Typhoon Bopha reached peak intensity and then immediately made landfall along the coast of the Philippine island of Mindanao. The rare low latitude howler was the most significant landfall on the island since at least Kate in 1970. The system caused more than 1000 deaths in the Philippines.

December 8, 2002 (15 years ago) -- Category 4 SuperTyphoon "Pongsona" struck the island of Guam, causing extensive damage in the US territory and in some other parts of the Marianas. It is the last major typhoon to directly hit Guam.

Wow 15 years already. Since then Guam has been very lucky with many near misses despite being in the prime spot in the world's most active basin. We are just a dot anyways. :lol:

December 16, 1997 - 20 years ago...
Typhoon Paka passed between the Southern Mariana islands of Guam and Rota.

About 2 days after, Super Typhoon Paka reached its peak intensity - 160 knots!

What a way to end 1997. It's one of 3 typhoons to peak at 160 knots and one of 10 Cat 5's to occur in the same year. This season is the most historic and most powerful the world has ever seen. Nothing even comes close.

December 31st, 1952: 65 years ago.

Super Typhoon Hester becomes a category 5 while entering the Philippine Sea to the south and west of Guam. This is the latest category 5 on record for the Northern Hemisphere. Hester's listed peak intensity of 160 kt is likely overdone, and I don't have direct access to the storm's recon data, but based on the 918 mb minimum pressure listed in the td9635 dataset at 18Z December 31st, 1952, a category 5 intensity certainly appears reasonable if not likely. Hester would maintain this intensity into the new year (920 mb on 00Z January 1, 1953), becoming the only Northern Hemisphere category 5 year crosser that I am aware of.

May 02, 2008 -- It has been a decade since Category 4 Cyclone "Nargis" struck and devastated southern Myanmar(Burma). The powerful cyclone whipped up a storm surge as it came ashore on Myanmar's low-lying and densely populated Irrawaddy delta/region, causing catastrophic destruction and killing about 140,000 people.
The staggering aftermath of Cyclone Nargis is largely due to unpreparedness, and the fact that this part of Myanmar is not frequently hit by cyclones. It is the worst natural disaster in the country's history, the deadliest named-TC in the North Indian ocean, and the second-deadliest named-TC globally.

June 21, 2008 -- From 10 years ago, Typhoon "Fengshen"(PH name "Frank") reached peaked intensity as it was moving over the central Philippines.
Typhoon Fengshen killed over 1000 people in the country, majority of these were people on board the ferry "MV Princess of the Stars", which capsized off the coast of Romblon at the height of the typhoon.

One of the more impressive typhoons to strengthen while crossing the Philippines.

August 18, 1983 -- Hurricane Alicia from 35 years ago...

https://noaahrd.wordpress.com/2018/08/1 ... ne-alicia/
In the early morning hours of August 18, 1983, Hurricane Alicia made landfall at San Luis Pass, Texas just southwest of the Galveston area. Its 115 mph (185 km/hr) winds slammed the high-rises of Houston leaving billions of dollars in damage in its wake.

Because of its slow pace and rapid intensification, Alicia proved an excellent case study for scientists. HRD was able to fly four Long Term Monitoring missions during this critical period from rapid intensification to landfall. The NOAA aircraft Doppler radars and the NWS land-based radar were able to map out the inner core winds of the storm, which provided the first detailed look at primary and secondary circulation of a major hurricane. The dataset also provided information on mesoscale updrafts and downdrafts in the rainbands, was a confirmatory case of eyewall replacement cycles, and mapped the changes in the hurricane structure as it came ashore.

September 13, 2008: ten years ago, Hurricane Ike makes landfall in southeast Texas at 0700Z, which coincidentally was one year to the hour after Humberto made landfall in nearly the same location. The former category 4 hurricane made landfall as a sprawling 95 kt/950 mb category 2 and brought an extensive storm surge with up to 17 feet of inundation to areas near and right of the center track, causing some of the worst surge damaged ever witnessed. This is actually a storm I experienced firsthand, measuring a 969 mb pressure in the western eyewall not long after landfall at my parents's house.
