Re: Tropical Cyclone-Related Anniversaries [Five-year Intervals Only]
45 years ago today, The remnants of typhoon Nina produced an localized area of extreme rainfall over China's Henan province, causing 62 dams to fail. 1631mm (64.1 inches) of rain fell on Banqiao dam reservior over the course of the event including, reportedly, 33 inches (838mm) in 6 hours. The dam collapsed and inudated 3 million acres (12040 sq km) of land downstream. Very little information on the disaster was available at that time, but as many as 230,000 people perished in the flood and subsequent famine and epidemic. Nina remains to date the fourth deadliest tropical cyclone in world history and the second deadliest in the Western Pacific, after the Haiphong typhoon of 1881.

Re: Tropical Cyclone-Related Anniversaries [Five-year Intervals Only]
We're approaching the 60th anniversary of Hurricane Donna (1960), and a few days after it struck Florida a Miami television station's "weatherman" interviewed then-NHC Director Dr. Gordon Dunn, who gave a very low-tech but interesting explanation of the hurricane's long and destructive trek:

A second Miami television station put together their own post-Donna coverage:

Dr. Dunn retired in 1967 but still liked to visit us a few times each week through the 1980s, just to check the weather. He passed away in 1994.

On this day in 2005, Hurricane Katrina made landfall in southeastern Louisiana at 11:10 UTC (6:10 a.m. CDT) as a high-end Category 3 hurricane with winds of 125 mph and a pressure of 920 mb after having peaked as a Category 5. It caused catastrophic damage especially in New Orleans, where the levees failed, resulting in over 1,500 deaths and a staggering damage cost of $125 billion.

Re: Tropical Cyclone-Related Anniversaries [Five-year Intervals Only]
It didn't help reduce the surge any, but in the above loop it is clear how much the back half of Katrina's eyewall had degraded by time of landfall (much more so than Laura's despite the lower reflectivity on LCH before it was knocked out). The same was true for Ivan, in fact in my opinion the numerous landfalls of the 2004-'05 seasons likely contributed to the popular perception that strong major hurricanes "always" weaken on approach to the northern Gulf Coast.

At 7:37 PM, exactly 115 years ago - Steamer S.S. Pathfinder anchored in San Policarpo Bay, Philippines recorded a minimum barometric pressure of 920.08 hPa during the passage of "The Cantabria Cyclone"

Re: Tropical Cyclone-Related Anniversaries [Five-year Intervals Only]
We missed by a day the 15-year anniversary of Hurricane Rita's landfall, which was nearly duplicated by Laura this year (slightly further east, and much stronger although without the sub-900mb Cat. 5 open-Gulf peak).
Rita at peak also had a gorgeous satellite presentation which I personally think was more impressive than either Katrina or Wilma.

Re: Tropical Cyclone-Related Anniversaries [Five-year Intervals Only]
This week features the anniversary of some very intense TCs in recent history, 5 yrs apart. Atlantic's Wilma('05) peaking @ 160kts 882mb, STY Megi('10) hitting Luzon @ peak of 160kts 885mb, and EPac's Patricia('15) @ record 185kts 872mb! All had recon aircraft flown into them.

Kinda sad that Wilma and Patricia had regular recon missions but Megi didn't.
Recon found 175 knots or 200 mph in a research mission. Evidence that cannot be ignored. Peaked in between missions!
Also Patricia is the loner from the EPAC because of recon.
Regular WPAC recon stopped in 1987.
As they penetrated Megi's eyewall, the Hurricane Hunters performed the standard practice of maintaining a constant "pressure altitude"--the altitude one would expect to find a 700 mb pressure at in an atmosphere at standard conditions. In order to maintain a constant pressure altitude of 10,000 feet, the aircraft was forced to descend 3,000 feet in altitude as it entered Megi's eye. The aircraft entered the eye at 7,000 feet, so the pressure in Megi's eye was what one would normally find at an altitude 3,000 feet higher in the atmosphere. The aircraft recorded a remarkable increase in temperature of 12°C (22°F) as it crossed from the eyewall into the warm eye of Megi. A 12°C rise in eye temperature is extraordinarily rare in a tropical cyclone. Equally noteworthy were Megi's winds. The Hurricane Hunters measured winds at flight level of 220 mph, which normally translates to a surface wind speed of 198 mph, using the standard 10% reduction. The SFMR surface wind measurement instrument recorded surface winds of 186 mph in regions where heavy rain was not contaminating the measurement, but found surface winds of 199 mph in one region of heavy rain. Now, this measurement is considered contaminated by rain, but at very high wind speeds, the contamination effect is less important than at lower hurricane wind speeds, and it is possible than Megi's surface winds reached sustained speeds of 200 mph.

For Wilma, Patricia and Megi, recon passes were all at 12-hour intervals near the peak.

On this day in 2005, Hurricane Wilma became the strongest known Atlantic hurricane pressure-wise with a pinhole eye.

Well today is the 5 year anniversary of Hurricane Patricia's record 215mph winds. Can't believe it's been 5 years already...

Giri's rate of intensification was incredible with the little time/space it had over the northern Bay of Bengal.

Re: Tropical Cyclone-Related Anniversaries [Five-year Intervals Only]
On this day, 25 years ago - Super Typhoon Angela reached her peak intensity while off the coast of Bicol region.
Now, here we are in Southern Luzon, facing a dejavu of Angela.
Same letter R designation by PAGASA
Almost the same time frame
Nearly identical track across the archipelago,
Both during La Nina condition.
