Preface
In recent years, with the impact of climate change, extreme weather events have occurred frequently, which has had a great impact on people's production and life. In particular, heavy rains often cause serious flood disasters, which pose a great threat to social and economic development and the safety of people's lives and property. It is particularly important to understand the forecast information of heavy rain weather in a timely and accurate manner, strengthen the awareness of prevention, and make preparations for flood prevention.
Recently, under the influence of the rainy season and cyclones, heavy rainfall has occurred in many places in the eastern countries, and some places have also suffered serious floods. In order to remind people to pay attention to precautions in a timely manner, the meteorological department has issued a timely warning of heavy rain weather and reminded people to do a good job of prevention. So, in the next period of time, what impact will the heavy rain weather have on the meteorological situation of the eastern countries? And how can we deal effectively with this weather process? Let's find out.
A red warning for heavy rain was issued today
According to the National Meteorological Center, under the influence of the plum rainy season and cyclones, from tonight to July 2, there will be a relatively heavy rainfall weather process in the eastern countries, among which, there will be heavy rains, heavy rains and extremely heavy rains in some areas, and the maximum rainfall can reach 260 mm. For this reason, the meteorological department gave an early warning of this rainy weather process, and this morning, the red warning signal for heavy rain was officially released.
According to the forecast of the meteorological department, the rainy weather process has a wide range of influences, mainly distributed in Beijing, Shandong, Jiangsu, Anhui, Shanghai, Zhejiang, Hubei, Hunan, Guizhou and other places, and under the influence of the subtropical high pressure, the rainy weather process will continue to move northward, and North China, Huanghuai and other places will also be affected by a certain amount of rainfall.
The rainstorm process will shift northward
The formation of this rainstorm is closely related to the joint influence of the subtropical high and the western Pacific subtropical high. It is expected that due to the combined influence of these two high-pressure systems, the center of the main area affected by rainy weather will appear in the Jianghuai and Jiangnan areas, which is why the red warning signal for heavy rain has been issued in these places.
With the passage of time, the influence of the subtropical high gradually expands, and the rainstorm weather process will also follow its influence to the north, it is expected that starting tomorrow, the main affected area of the rainy weather will appear in the Huanghuai, Fenwei Plain and other places, and under the influence of the western Pacific subtropical high, the rainy weather process will also have obvious heavy rainfall weather, which will have a certain impact on the local crop growth and urban drainage system.
The rainfall process may alleviate the drought situation
Although this rainy weather process has had a certain impact on the production and life of some places, from the perspective of the overall meteorological situation, the emergence of this rainy weather process has a positive significance for the meteorological situation of the eastern countries. Because, at present, the meteorological situation in the eastern countries is dry as a whole, and there have been different degrees of drought in some places, and the emergence of this rainy weather process can just bring a certain amount of rainfall supply to the drought areas and play a certain role in alleviating it.
In particular, due to the influence of the Meiyu season and cyclones, the Meiyu belt in the middle and lower reaches of the Yangtze River has been relatively active, which also provides favorable conditions for rainfall recharge in arid areas. Moreover, with the influence of this heavy rainfall weather process, the Meiyu belt will continue to shift northward, and the rainy weather in the middle and lower reaches of the Yangtze River will still be relatively obvious in the next week, which will play a certain positive role in the rainfall supply in the drought areas.
Responses need to be considered comprehensively
Although this rainy weather process has a certain alleviating effect on the drought areas, in the specific flood prevention and flood control work, the local authorities and relevant departments should not take it lightly, and the countermeasures need to be comprehensively considered. On the one hand, it is necessary to strengthen the monitoring of the rainy weather process, keep abreast of the development and changes of the rainy weather process, and do a good job in all preparations for flood prevention and flood control.
On the other hand, it is also necessary to strengthen the assessment of the rainfall weather process, grasp the impact of rainfall weather on the local ecological environment and crop growth in a timely manner, and do a good job in the assessment of disaster risks, so as to provide a scientific basis for decision-making in flood prevention and flood control. Moreover, in the specific work of flood prevention and flood control, it is also necessary to do a good job in preventing flood disasters, strengthen the construction and management of urban drainage systems, and improve the city's ability to resist disasters.
epilogue
The occurrence of heavy rain has had a certain impact on the meteorological situation of the eastern countries, especially for the rainfall supply in the drought areas. In the face of the impact of heavy rains, we must not take it lightly, and we should strengthen the construction of meteorological monitoring and early warning systems, enhance the public's awareness of prevention, and do a good job in flood prevention and flood control, so as to effectively reduce the impact of heavy rains on the social economy and the production and life of the people, and ensure the safety of the people's lives and property.
It is hoped that everyone can maintain a high degree of vigilance and take precautions during the rainstorm, and also hope that the rainfall in the drought-stricken areas can be stopped in moderation and have a positive impact on the growth of local crops and the restoration of the ecological environment.
