News 1+1丨How to prevent extreme weather this year?
Strong winds, cooling, rainfall, hail, and recently, many provinces across the country have experienced the most violent convective weather this year.
Among them, Anyue County in Sichuan suffered the strongest wind since 1957.
How do you view the coming of strong convective weather?
What are the characteristics of our country's climate this year?
How can we improve our ability to deal with extreme weather?
"News 1+1" invited Sheng Jie, deputy chief of the strong weather forecast center of the Central Meteorological Observatory, and Yang Jiguo, deputy chief of the National Early Warning Information Release Center, to continue to pay attention to: How to prevent extreme weather this year?
The most intense severe convective weather this year is coming, is it normal?
Sheng Jie, deputy chief of the strong weather forecast center of the Central Meteorological Observatory:
Up to now, from the monitoring situation, the strong convective weather in China in spring is still normal as a whole, because in the central and eastern parts of China, spring itself is a frequent and high incidence of strong convection. season.
From the statistical results, generally speaking, there will be 3 to 5 strong convective processes in my country in April, which will also be accompanied by extreme weather. So far, it has occurred 3 times, which is normal in terms of frequency.
However, from the perspective of local extremes, large hailstones or even extreme winds in some localities are not normal.
One of the characteristics of this severe convective weather is that the area of occurrence is slightly norther and wester than previous years.
But overall, the overall strong convection in April this year is normal.
In the first ten days of April, the local temperature in some parts of northern my country has exceeded the historical extreme value for the same period. What should we pay attention to?
Sheng Jie, deputy chief of the strong weather forecast center of the Central Meteorological Observatory: On the one hand, the meteorological department needs to be vigilant and pay attention to the sudden temperature rise in spring, because it will bring about drastic changes in temperature and have a great impact on people.
On the other hand, it will also inspire some local extreme convective weather.
For the public, it is necessary to pay attention to the weather forecast in time. Because of the early temperature rise, they put on summer clothes, but maybe under the influence of cold air, they will soon change into spring clothes, and even prepare to be alert to the occurrence of strong convective weather.
Therefore, this high temperature weather is a very important signal to be alert to strong convective weather in the early stage.
Will the recent strong convective weather affecting many places in my country continue?
Sheng Jie, deputy chief of the strong weather forecast center of the Central Meteorological Observatory: There should be strong convection processes in the middle and late April. According to the current research and judgment, in the next 3 to 5 days, except for Yunnan and other places in my country, most other areas will not temporarily Severe severe convective weather occurred.
However, as the temperature rises further in mid-to-late April and is affected by cold air, extreme weather may continue to occur in central and eastern my country.
We still need to maintain a high degree of attention to prevent and respond to the occurrence of extreme weather.
How to continuously improve the ability to deal with extreme weather?
Yang Jiguo, deputy chief engineer of the National Early Warning Information Release Center: Not only northern cities, but every city in our country must make corresponding preparations to deal with the impact of climate change.
For example, there are many places in the construction of resilient cities, which can rely on their own capabilities to resist disasters, reduce disaster losses, and allocate resources rationally, so that cities can quickly recover from disasters.
In the long run, we can also learn from past disasters and accidents to improve our ability to adapt to disasters.
In addition, there is a rapid response mechanism established by our whole society, guided by weather warning signals. Our transportation, agriculture, construction and other industries have different defense priorities when facing the same disaster. Ordinary people also know how to How to defend, I think these are actually a good way for us to deal with this ability.
Early warning is an important first line of defense against extreme weather
Yang Jiguo, deputy chief engineer of the National Early Warning Information Release Center: Extreme weather has brought serious challenges to economic and social development. Therefore, it is very important to strengthen the early monitoring, early warning and assessment of climate change risks and improve the climate resilience of the whole society.
And strengthening the construction of multi-hazard early warning system is one of the good practices, which is also a practice that the World Meteorological Organization has been promoting globally in recent years.
In fact, our country has completed the construction of the national emergency early warning information release system in 2015, and built a "one vertical and four horizontal" early warning release business system, which can release early warning information to the society quickly, in multiple ways, and accurately. excellent results.
In addition, the content of the early warning signals is added to the warning of meteorological risks, so that the public can understand the early warning and identify risks through the early warning signals of meteorological disasters, so that the defense can be more targeted, and improve the defense ability of meteorological disasters. These are actually very good. Solution.
