Which is bigger, new york rainstorm or Zhengzhou rainstorm?

The rainfall in new york is equivalent to the storage capacity of 50,000 Olympic swimming pools. The water storage capacity of Olympic swimming pools is about 3,000 square meters, 50,000 swimming pools are equivalent to 65.438+0.5 billion cubic meters, and Hangzhou West Lake is equivalent to 65.438+0.4 West Lakes in five hours, while the maximum value in Zhengzhou is 654.38+0.4 West Lakes in two hours.

The five-hour rainfall in new york reached 35 billion gallons, or 65.438+300 million tons of water. Just after the Olympic Games, you should remember how big the swimming pool is, 50 meters long and 25 meters wide. This wave of rainfall is equivalent to 50,000 swimming pools.

If you haven't seen a standard swimming pool, you should have been to Hangzhou West Lake. The water volume of the West Lake is almost14.29 million cubic meters, so the five-hour rainfall in new york is equivalent to 10 West Lake.

According to local reports, rainfall of this scale only occurs once every 200-500 years.

Speaking of which, you will inevitably think of the rainstorm in Zhengzhou some time ago. Compared with this heavy rain in new york, which is bigger?

The daily rainfall in new york is more than 180mm, while that in Zhengzhou is more than 550mm, and the hourly rainfall in peak hours is more than 200mm.

According to the meteorological records of Zhengzhou in previous years, the daily rainfall exceeded 180 mm, which appeared many times.

If the West Lake is taken as the reference standard, the rainstorm in Zhengzhou is equivalent to 170 West Lakes.

Therefore, by direct comparison, the rainstorm in new york is far less than that in Zhengzhou.

Next, let's look at the reasons why they are different.

The rainstorm in Zhengzhou is due to the influence of the climate of Henan vortex system. Although the typhoon fireworks was more than 0/000 kilometers away from Henan/Kloc-at that time, it came from the ocean and carried a lot of water vapor, so the water vapor would be replenished in the east of Zhengzhou. In addition, Henan is located near Taihang Mountain, and heavy precipitation is caused by terrain uplift.

In fact, the reasons for this rainstorm in new york are similar, all due to the influence of Hurricane Ida. To some extent, the topographical features of the eastern part of the United States are very similar to those of our eastern part. They all face the ocean and there are big cities along the coast.

Let me explain here that some people don't quite understand the difference between a typhoon and a hurricane. In fact, although these two names are different, they are the same in nature and belong to tropical cyclones. They are all tropical cyclones, and the central wind force 12 is above, that is, more than 32.7 meters per second.

It's just called a hurricane in the Atlantic and the eastern Pacific, and a typhoon in the western Pacific.

Since the beginning of this year, whether it is Zhengzhou rainstorm, Hangzhou rainstorm or new york rainstorm, it shows that extreme weather is becoming more and more frequent all over the world.

You know, the main reason behind it is global warming.

The rising temperature will make a lot of water vapor evaporate, and they will condense and rise in the atmosphere, leading to an increase in rainfall, which is the same reason that small water droplets will appear on the surface of popsicles placed indoors.

Compared with the temperature around the world, the global average temperature has increased by 0.5 ~0.8 in the last hundred years. You know, every time the average temperature of the earth's surface rises by 1 degree Celsius, the atmosphere can hold about 7% more water. If it rises by 6 degrees, the land will be directly submerged and all species will be extinct.

Not to mention the personal experience of a small partner in Zhengzhou. Just looking at the data, we know that the rainstorm in Zhengzhou was much bigger than that in new york in September.

As for the rainfall in new york, according to the data of the National Weather Service, the rainfall in several hours is as high as 7. 19 feet (about 18.26 cm), which is more than 1.6 times the average rainfall in new york in September. The maximum rainfall in new york occurs from 20: 00 pm to 2: 00 pm on September 20th of 1 year, and the precipitation within 1 hour is 3.24 feet (about 8.23 cm).

Similarly, when the maximum hourly rainfall in Zhengzhou and new york is converted into millimeters, the maximum hourly rainfall in new york is about 82.3 millimeters, and that in Zhengzhou is 20 1.9 millimeters. The maximum rainfall in Zhengzhou is 2.4532 199270959905 times that in new york. This multiple is an accurate number calculated by a calculator.

So the rainstorm in Zhengzhou is much heavier than that in new york.

After landing in the United States, Hurricane Ida raged all the way, causing heavy rains and floods in new york and New Jersey. So far, eight people have been killed in new york.

Zhengzhou is a northern city, which goes deep inland and lacks the experience and ability to fight against heavy rain. Be caught off guard by the sudden disaster. New york and New Jersey, as well as Louisiana, which was attacked by Ida before, are all coastal areas and should be very good at handling this situation. In fact, their precipitation is far less than that of Zhengzhou, but it is not better than Zhengzhou.

As a coastal city, new york should be better than Zhengzhou in coping with storms and floods.

Americans call the rainstorm in new york "unprecedented", reaching the local standard of once in 500 years. New york entered a state of emergency, many places were flooded, the flood flooded into the subway, and the whole city was paralyzed.

New york was hit by a rainstorm, which was a bit unexpected, not as big as Zhengzhou, but the losses were much more serious.

Zhengzhou! I've experienced it myself! It's fine to travel in the morning, but I can't go back in the afternoon, alas, I can't go back! I just want to make money, but Zhengzhou wants my life [covering my face]. Return to the city from Xinzheng in the afternoon! Because it is a bus, most sections can still be crossed, and the master is very helpful, but the car is not very good, and there are too many cars lying on the nest along the way! After seeing the guests off at Zhengzhou East Station, the master dropped me and another tourist off at Nongye South Road subway station. At this time, when we got off the bus, it was probably a little after 4 o'clock, and the water on the road was knee-deep! I have no choice but to bite the bullet and take the subway, 1 line. I originally planned to get off at Zhuang Yan and take the bus! Who knows, after I got out of the subway station, I found that there was water on the BRT platform, and the water on the road reached my thigh, so I had to continue to take the subway to Zijingshan Station and fantasize about a bus! After leaving the station, I found that it was no different from just now. I have no choice but to follow people, lie in the water and walk in the direction of home! After walking for two hours and swimming, I finally got home. The power went out on the 32nd floor. This despair! Flooded shops and cars soaked in water can be seen everywhere on the roadside, too many!

From Wednesday to Thursday, local time in the United States, affected by Hurricane Ida, heavy rainfall swept across many places in the northeastern United States. At present, extreme weather has affected new york, New Jersey, Pennsylvania and other places, causing at least 40 deaths.

According to the monitoring data of the US Weather Service, the rainfall reached18cm in a few hours, breaking the historical record. New york Mayor Bill Bill de Blasio declared a state of emergency in new york on Wednesday night due to "historic weather events". The new york office of the National Weather Service issued a flash flood emergency for new york for the first time in history, warning people to look for high ground immediately. On Wednesday night, all subway lines in new york were suspended, the agency said on Twitter.

Not long ago, on July 18, a rare rainstorm occurred in Zhengzhou. The average rainfall in the city is 449 mm, which is said to be once in a thousand years. As a native of Kaifeng, Kaifeng was also deeply affected by this disaster. Xinxiang, Kaifeng, Zhengzhou, Weishi and other places have suffered from floods to varying degrees.

The rainstorm in new york, with the capacity of nearly 8 West Lakes in an hour, is only moderate compared with Zhengzhou!

The waterlogging in Zhengzhou city is serious, and the whole city of Zhengzhou has become a Zeguo. Officials have previously announced that the flood has caused 0/2 deaths in Zhengzhou. It is said that there must be a great epidemic after a great disaster. Zhengzhou was also listed as a high-risk area a few days after the disaster, because Kaifeng was close to Zhengzhou, and all activities were suspended.

In the face of natural disasters, we look so fragile and live well. At the same time, do we have to reflect?
