Recently, under the influence of severe convection weather, severe weather such as thunder and lightning, rainstorm and gale occurred in many places of Jiangxi, causing casualties, collapse of houses and disaster of crops; Guangdong has entered the season of heavy rainfall and severe convection, and a large range of heavy rainfall weather has occurred. Flood control emergency response has been launched in many places, and all efforts have been made to do a good job in flood control and disaster relief. For a period of time, extreme weather has occurred frequently in China, posing a serious threat to the safety of people's lives and property, and also ringing the alarm bell for building a secure defense line.

It should be noted that extreme weather has its occasional nature, but it does not mean that there is nothing left to do. Under the background of global warming, the frequency of extreme weather increases. It is urgent to establish the awareness of normalization of extreme weather and make adequate preparations for normalization of defense. In fact, the more sudden extreme weather occurs, the more it reflects the lack of solid work and awareness of disaster prevention. According to the prediction of relevant departments, this year's flood season in China is accompanied by drought and waterlogging, which is more serious than drought. Rainstorms and floods of varying degrees may occur in all seven major rivers in the country, and periodic drought may occur in some regions. In the face of various possible adverse factors, we must attach great importance to and take precautions to win the initiative of disaster prevention and reduction.

In order to cope with extreme weather, we must be prepared and turn passive response into active action. In response to this extreme weather, Jiangxi Meteorological Department held two provincial weather conferences and issued four red warning messages for rainstorm, hail and gale across the network, covering a total of 10.26 million people. Shandong has deployed this year's flood prevention preparations in an early and strict manner. It is required to fully consider various small probability, high risk and unconventional situations, carry out investigation and rectification of risk hazards, and resolutely put an end to "flooding with diseases". Only by compacting responsibility, strengthening monitoring, forecasting and early warning, strengthening patrol duty, focusing on key parts, implementing detailed measures, and transforming the responsibility of "always reassuring" into the action force of "everything is in the heart of the bottom", can we be fully prepared and minimize all kinds of losses.

In response to extreme sudden weather, we should also strengthen the bottom line thinking and always tighten the safety string. The more rain and high waves, the more mission. At present, the extremes, anomalies, complexity and uncertainty of weather have increased significantly. We must maintain a sense of responsibility, mission and urgency to do a good job in all work. Are there any plans for "closing, stopping, withdrawing and turning" and rescue measures in extreme weather? Has the prevention work been implemented in key areas such as mountain flood prone areas, industrial and mining enterprises, and chemical parks? To be responsible, responsible and conscientious, we must put the safety of people's lives and property first, never let go of any early warning, never neglect any round of danger, never slacken any disposal, and ensure that emergency rescue can be carried out as soon as possible in case of emergencies and disasters.

It should also be noted that everyone is the first person responsible for safety. In the face of sudden extreme weather, we should pay attention to the forecast and warning information of severe convection weather in time and take protective measures in time. For example, when a thunderstorm occurs, enter a building with lightning protection measures to avoid and stay away from dangerous power sources; In the process of severe convection weather, it is necessary to minimize going out, keep away from scaffolding, billboards and other structures, and avoid entering into culverts, underground passages and other ponding places; When suddenly attacked by mountain torrents, choose the nearest safe route to run horizontally along the hillside; wait. It can be said that everyone needs to improve their awareness of flood prevention and risk avoidance and their ability to help themselves and each other, and they are all part of building a secure defense line.

The weather is changeable, and the sense of being cautious in disaster prevention and resistance cannot change. To enhance the ability and level of meteorological prediction, eliminate various risks and hidden dangers, and protect the safety of life and property, we must not relax for a moment, and must always be online.
