Hello everyone, here is the "Tropical Cyclone (Typhoon) Story Collection" at the top of the Purple City, welcome to watch the wonderful content of this issue.
Typhoon Sammy: Haiyan > Weimasson > Sammy > = 7314 Mag> Moranti This ranking is beyond doubt.
Haiyan is undoubtedly the strongest landing typhoon, Weimasson strength is significantly stronger than Sangmei, please check the literature or typhoon yearbook on Baidu.
Haiyan destroyed almost all of the wind speed meteorological equipment on the path of the phoenix eye before landing in the Philippines.
The most accurate data for the time of landing cannot be obtained.
But judging from the satellite cloud map and radar display, the core cloud map before login is perfectly round.
And it's huge, with a tight, round eye, which is very rare, with a one-minute sustained wind speed of 305k when Petrel logs in.
Typhoon Sammy: Haiyan > Weimasson > Sammy > = 7314 Mag > Moranti
There is no doubt about this ordering.
Haiyan is undoubtedly the strongest landing typhoon, Weimasson strength is significantly stronger than Sangmei, please check the literature or typhoon yearbook on Baidu.
1. Haiyan 11th century wind king
Haiyan destroyed almost all of the wind speed meteorological equipment on the Path of the Phoenix Eye before landing in the Philippines.
The most accurate data for the time of landing cannot be obtained.
But judging from the satellite cloud map and radar display, the core cloud map before login is perfectly round.
And it is very large, the eye is round and compact, which is very rare, and the one-minute continuous wind speed of Haiyan when it logs in reaches 305km/h, and the wind speed is 84 m/s!!! 170kt。
Even if there is no measured data, this is the strongest typhoon on record!
Intensity assessment
Based on satellite observation, radar observation, meteorological station measurement and wind pressure relationship, the Chinese Meteorological Department will assess the Lai peak intensity of Weimaxun as 890 hPa and 70-75 m/s (above 17 levels) in the Typhoon Yearbook, 890 hPa and 70 m/s (above 17 levels) in Hainan, 910 hundred things, 60 m/s (17 grades), and 950 hundred sleeves and 48 m/s (15 levels) in Guangxi.
Satellite observation: According to the Typhoon Intensity Objective Estimation System (Advanced Dvorak Technique, abbreviated ADT) developed by the Cooperative Research Institute for Meteorological Satellite Research and Charging (OIMSS) of the University of Wisconsin, version 8.1.4, according to the standardized IR-BD cloud map, the maximum DT index of Weimasson is 7.2, corresponding to the air pressure of 891.7 hPa, and the wind speed is 75m/s (above 17 levels).
Radar observation: According to the Haikou radar speed measurement, the maximum radial speed at 12:46 is 93.1m/s, which can be used as the basis for the maximum gust, and this wind speed is about 74m/s after multiplying by 0.8, which can be used as a definite strength basis.
Meteorological station measurement: Beishi Island recorded the lowest station pressure of 881.2 face pa at 13:21, and the air pressure at sea level was 899.2 mian pa.
At this time, the island has not yet fully entered the eye of the Typhoon of Weimasson, and the minimum pressure of Weimasson should have a reasonable downward adjustment space on the basis of 899.2 hPa.
Wind pressure relationship calculation: According to the wind pressure relationship calculation of Atkinson & Holiday (1977), Yan Fangjie et al. (1994), Guard &M.A. Lander (1996) and others, with 899.2-888 hundred sleeves as the floating fan country of Weimasson's lowest air pressure, the maximum wind di of Weimasson is 70-76m/s.
2. Typhoon Weimasson
The strongest typhoons that make landfall on the mainland, including the Taiwan region.
Rare South China Sea Category 5 typhoon!
The wind force of Wenchang is above 17 levels 70-75 m/s, and the air pressure is 890 hPa.
The wind force of xuwen in Guangdong is 17 levels 60 m / s, and the air pressure is 910 hPa.
The wind force landing in Fangcheng Port in Guangxi Province is 15 meters per second and the air pressure is 950 hPa.
Weimasson strengthened into a super typhoon 6 hours before landing in Wenchang, Hainan, strengthened to level 17 4 hours before landing, and reached a peak of 17 or above 2 hours before landing!
Before logging in, Beishi Island, 30 kilometers away from Wenchang, measured the maximum sustained wind near the center for 10 minutes and 58.7 m/s!
Sea level air pressure 899 hPa! (Prior to this, the continent had never been recorded to last nearly 60 m/s for 10 minutes, and the air pressure of 899 also broke the record for the lowest air pressure on the Asian land)!
However, this still did not fully enter the data of the eye of the typhoon, and then the wind tower was destroyed by the wind. Unable to get data closer to the eye of a typhoon!
At Wenchang Buoy Station, 35 kilometers southeast of Beishi Island, it was even more tragic that the typhoon had not yet made landfall.
The meteorological equipment around Wenchang and Haikou has been blown down and cannot obtain accurate data, but according to the radar bottom scan feedback data, the maximum radial speed of Weimasun in the first two hours of landing in Wenchang, Hainan Is 93 m/s, which is 74 m/s instead of wind speed!
The following satellite cloud map can be seen that Weimasun continued to strengthen before landing in Wenchang, Hainan!
The wind ring is spinning faster and faster!
According to the changes in the satellite cloud map, Weimasson did not reach the peak of intensity until it landed in Wenchang, Hainan, and the satellite cloud map showed that the core cloud cluster was getting rounder and rounder.
The following radar chart shows that the typhoon eye was in a perfect circle 4 hours before the Wilmason login, and the continuous contraction became smaller and tighter, until it reached the most perfect form before logging in.
This is a very rare outbreak typhoon!
This is a sammy satellite cloud map of the time of landing.
It can be seen that the core cloud of Weimasson is much better than sammy, the core cloud structure of Weimasson is thicker, and the vertical structure of the eye wall is complete and denser.
Means that convection is more intense.
Before sammy landed, the structure of the wind eye began to weaken and no longer appeared perfectly round, and the bottom layer of the wind eye had been filled with clouds, and the core cloud cluster began to loosen, which was a phenomenon in a weakened state.
For the size of the circulation, everyone has a misunderstanding that the Sammy circulation is small and energetic.
Data from the pressure reduction speed data from the Beishidao air pressure station shows that Weimasson set a record for the fastest 1 minute buck of 9.1 hPa.
It shows that the air pressure gradient near the center of Weimasun is very large.
It shows that the core circulation of Weimasson is smaller than Sammy, and the explosive force is stronger than Sammy.
Later, the United Meteorological Department of the United States also gave a rating of 75 m/s of the Weimasson landing intensity.
After the National Weather Service also went to the disaster area to check the disaster situation, compared to the wind damage of Sammy, it was concluded that the wind damage of Weimasun was much more serious than that of Sammy!
Finally, the assessment was made: the strength of the Wimasson landing was 70-75 m/s, and the air pressure was 890 hPa. Both indicators are the highest since the founding of the People's Republic of China.
Poor thing is that Wei Ma Xun caught up with Ma Hang, and the media paid attention to Ma Hang.
Few mainstream media pay attention to the disaster area!
The disaster of the Wilson landing in a nearby township:
After the typhoon, I personally went to Changsa, 10 kilometers away from the typhoon's landing site, Wengtian Town, to take a look, which was simply shocking!
The 30-meter-high 100,000v all-steel high-voltage power tower is almost all discounted!
This is an all-steel structure!
Continue to look deeper, the roadside can always see the sea, because all the trees in a radius of several kilometers have been thrown to the ground, and there are no columns to block the view!
Even if it didn't fall, it would have been beaten and only the trunk was bare!
In some villages, all the tile houses have collapsed or lifted their roofs, and only a few leaves of coconut trees are left, and the rest are all light poles!
It's a tough fight with the petrels that the Philippines encountered.
3. Typhoon Sangmei
In 2006, it made landfall with the strongest typhoon on the mainland and the strongest typhoon in central China.
Sangmei peak period is very strong is a typical five-level typhoon, in September 21, that is, nearly 100 kilometers away from the Diaoyu Islands, Sangmei reached the peak of strength, near the center of the maximum wind 17 or above!
140kt。
Air pressure 915 hPa!
But before the landfall, it had weakened to a category 4 typhoon, and the eye of the wind had become blocked.
However, when landing in the Zhejiang and Fujian areas, the maximum wind near the center also reached 17 levels and 60 meters per second!
2 minutes near the center with 60 m/s continuous wind!
Air pressure 920 hPa.
Maximum instantaneous wind speed of landing: 81m/s (measured by Hedingshan Wind Power Station at an altitude of 700 meters in Wenzhou, non-sea level wind speed, can not be used as strength measurement).
It brought devastating blows to the area around Cangnan and Fuding County.
Due to the small circulation typhoon impact range of Sammy coupled with the fast movement speed and strong intensity.
Most people don't realize that the typhoon is already coming.
Coupled with the weak awareness of some people to defend Taiwan, they relaxed their vigilance before the south wind came, and the quality of construction in township areas was not good at that time.
It is impossible to resist such a strong wind attack. So it caused thousands of casualties.
Due to the small circulation of Sammy, it quickly weakened and disintegrated after landing.
The following is a satellite cloud map of Sangmei, it can be seen that the peak of the Sangmei satellite cloud map is perfect, the eye is small and tight, the core cloud is round, but the structure of the eye of the wind begins to weaken 2 hours before logging in, and the core cloud begins to be filled.
After Sangmei landed at the border between Zhejiang and Fujian, the disaster was very serious, and countless houses collapsed, and hundreds of people were reported to have died.
Super Typhoon 4.7314 Marg
(Maximum wind at the center of the landing 60 m/s?) Lack of data to measure maximum wind speed)
Mention of this has to mention a forgotten super typhoon: 7314 small super typhoon Marg.
Marg strong strength and fast movement and is a small circulation typhoon, 6 hours before the login weather is clear, breeze, it is difficult to believe that there is a typhoon, coupled with the relevant departments of the prevention and publicity work is not in place, resulting in most people do not know that there is a big typhoon coming!
As a result, the three of them suddenly landed in Qionghai, Hainan in the middle of the night, caught off guard, and caused more than 900 deaths!
Before logging in, almost all the wind measuring instruments in the area were destroyed, and the most real data could not be obtained, and after the landing, the town of Jiaji in Qionghai was almost razed to the ground, and there was no upright building in the whole town!
All the trees were stripped naked, and not a single shade was there!
Judging from the comparison between the wind-destroyed photos and the Philippines attacked by petrels, there is no difference.
Unfortunately, there is a lack of data over time.
5. Meranti
The peak strength of Moranti is very strong, and it can be seen from the satellite cloud map that Moranti at the peak is perfect.
Typical Category 5 typhoon!
Peak moment near the center maximum wind 75 m/s!!!
The core cloud is almost a huge near-circle, and the eye of the wind is round and clear and deep, and you can almost see the blue sea.
It is a devastating typhoon, and a landfall of this intensity would be catastrophic.
However, Meranti was too close to Taiwan when passing through Taiwan, and was consumed by The mountains of Taiwan.
Therefore, there was a significant weakening when it was moved to the Taiwan Strait.
When it landed in Xiamen, Fujian Province, it had weakened into a strong typhoon, but the maximum wind in the center was still 15 meters per second!
Hit the Xiamen area hard.
A lot of greenery was destroyed, windows were broken, roads were flooded... The city was once paralyzed by water and power outages.
If Meranti had not passed through Taiwan and landed directly in Xiamen, the consequences would have been unimaginable.
6. Sky rabbit
Tiantu's peak period was also a five-level typhoon, and the intensity was 14 when it landed in Shanwei, Guangdong!
Tiantu reached its peak strength of 145kt on September 20, 2013! But dramatically, after reaching its peak, the Tiantu appeared with a double eye wall, resulting in a slight weakening of the "Tiantu".
At 17:00 on the 20th, the Joint Typhoon Warning Center downgraded it to a Category IV typhoon.
At 19:40 on September 22, the center of strong typhoon Tiantu made landfall on the southern coast of Shanwei City, Guangdong Province, China, with a maximum wind force of 14 (45 meters per second) near the center at the time of landfall, and a maximum sustained wind speed of 162 kilometers per hour at the center.
So in summary: Peak Strength Petrel > Meranti > Vermason > = Sammy > 7314 Mag > Sky Rabbit
Landing Intensity: Haiyan > WeiMasson > Sammy > = 7314 Mag > Moranti > Sky Rabbit.
There is no doubt about this ranking, please check the data survey if you are not convinced.
The article was written in more than two hours!
In particular, if you have doubts about the ranking of Weimasson and Sammy, please baidu or look at the Typhoon Yearbook.
Compared with Weimasson, it can be seen that the house can be seriously damaged.
However, after Sangmei, the trees on the mountain still have many leaves, and they are still green, and the vegetation around wenchangchangsa-Wengtian-Puqian town, the landing site of Weimasun, is almost all destroyed, and there is no green in sight, and the trees either fall or become light poles, and even the Tongguling Ridge, which is 30 kilometers away from the typhoon's landing path, turns dry yellow after the typhoon, because all the leaves of the trees on the mountain have fallen dry.
So:
Landing Intensity: Haiyan > WeiMasson > Sammy > = 7314 Mag > Moranti > Sky Rabbit.
If you don't trust the NFS data, there's no need for us to argue. Please respect history and respect authority.
