Since the beginning of summer this year, the north and south of the mainland can be described as two heavens of ice and fire. The southern region continues to be hit by heavy rainfall, and the precipitation in many places has exceeded historical extremes. In some areas of the southern part of the Yangtze River, for example, the cumulative rainfall has been close to 600 mm so far, which can be called the "violent rainy season". These areas are not only plagued by urban waterlogging, but also serious flooding of farmland, which has a huge impact on the production and life of local residents.
Heavy rains continue in the south, and drought in the north may ease
In the hot summer, the weather is always unpredictable. Recently, many places on the mainland have frequently encountered extreme weather, on the one hand, the south has continued to rain and disasters, and on the other hand, the high temperature and lack of rain and drought in the north have intensified. The latest weather forecast shows that this pattern of "flooding in the south and drought in the north" may be about to be broken.
In the next few days, many places on the mainland will usher in heavy rainfall, and some northern dry areas are expected to quench their thirst, but at the same time, they will also bring new challenges to some areas. Let's take a look at how this upcoming weather drama plays out.
Many places in the north continued to experience high temperatures and little rainfall, and some areas even experienced severe drought. The latest weather forecasts offer a glimmer of hope in these thirsty lands. According to the forecast of the Central Meteorological Observatory, from June 28 to 29, some parts of the northern part of the mainland will usher in long-lost rainfall. The timely rain is expected to alleviate the drought and provide much-needed water supply for crop growth.
According to meteorological experts, this shift in weather patterns is mainly influenced by the following factors:
1. The warm and moist airflow at the edge of the western Pacific subtropical high interacts with the Meiyu front, resulting in concentrated rainfall in the southern region.
2. The active Meiyu frontal system promotes the "train effect" of the heavy precipitation convection system, which aggravates the rainfall intensity in local areas.
3. Under the background of global warming, the El Niño phenomenon has shifted the western Pacific subtropical high ridge to the south, further aggravating the intensity of plum rains in the middle and lower reaches of the Yangtze River.
Rainstorm Warning: These areas need to be on high alert
According to the latest meteorological forecast, from June 28 to 29, many places in the mainland will usher in a wide range of heavy rainfall. Among them, heavy rainstorms may occur in northern Hunan, Hubei, southern Henan, northern Anhui, northern Jiangsu and other regions, and even extremely heavy rains in some areas. The extent and intensity of this rainfall process can be called the largest so far this year.
Meteorological experts reminded that due to the impact of this heavy rainfall, there may be strong convective weather such as short-term heavy precipitation, thunderstorms and strong winds in the above-mentioned areas. Due to the continuous high temperature and high surface temperature in the early stage, sudden heavy rainfall can easily cause the phenomenon of "drought and flood rapid turn", which can easily cause secondary disasters such as urban waterlogging and flash floods. Therefore, it is important for the relevant regions to take precautions in advance to minimize possible losses.
For areas that are about to experience heavy rainfall, the meteorological department recommends the following precautions:
1. Pay close attention to the latest weather forecasts and early warning information, and adjust work and life arrangements in a timely manner;
2. Strengthen the inspection and maintenance of the urban drainage system to ensure smooth drainage;
3. Residents in mountainous areas should be alert to geological disasters such as flash floods and mudslides, and move to safe areas in advance if necessary;
4. In rural areas, attention should be paid to strengthening agricultural facilities to protect crops from strong storms and rains;
5. Pay attention to traffic safety when traveling, and try to avoid outdoor activities during heavy rains.
Unexpected twist: the rain situation in Shandong has changed
Just when people thought that the rain in the north was a foregone conclusion, the weather forecast in Shandong Province took an unexpected turn. The previously forecast of widespread heavy rain suddenly reduced its scope and intensity. According to the latest forecast of the Shandong Provincial Meteorological Observatory, from the night of the 28th to the day of the 29th, only Lunan, Luzhong and the peninsula areas in Shandong Province had thundershowers or showers, and the western Luxi area was dominated by cloudy weather.
This change has undoubtedly brought a lot of disappointment to local farmers. The long-awaited rains will not alleviate the drought, and crop growth will continue to be threatened by the drought. However, meteorological experts said that although the scope of the rain has narrowed this time, there is still a chance of precipitation in Shandong in the coming days. From the night of the 29th to the day of the 30th, there will still be localized thunderstorms or showers in Weifang and the peninsula.
At the same time, the Shandong Provincial Meteorological Observatory continues to issue a yellow warning for high temperatures. On the 28th, the maximum temperature in the central and western regions will reach 36~38 °C, and some areas may even hit a high temperature of 40 °C. Fortunately, this wave of hot weather is expected to end on the night of the 28th, and the province will usher in a precipitation process.
In the face of such complex and changeable weather conditions, the agricultural department of Shandong Province reminds farmers that:
1. Pay close attention to weather changes and arrange agricultural activities reasonably;
2. Do a good job in field management and strengthen pest control;
3. Scientific allocation of water resources and the use of water-saving irrigation technologies as much as possible;
4. Proper soil mulching to reduce water evaporation;
5. Choose drought-resistant varieties to improve crop resistance to stress.
The warning behind the climate anomaly
In recent years, the mainland has frequently encountered extreme weather events, such as floods in the south and drought in the north, torrential rains and floods, high temperatures and droughts, and other meteorological disasters. Behind this climate anomaly, it reflects the profound impact of global climate change on the continental climate pattern.
Meteorological experts pointed out that in the context of global warming, the instability and extremity of the continental climate system have increased significantly. On the one hand, the increase in water vapor content in the atmosphere leads to frequent heavy precipitation events. On the other hand, the duration of hot weather is prolonged, which exacerbates the occurrence and development of drought. This climate change trend not only affects agricultural production, but also brings great challenges to urban management, disaster prevention and mitigation.
In the face of increasing climate change, experts are calling for:
1. Strengthen climate change research and improve the accuracy of meteorological forecasts;
2. Improve urban infrastructure and enhance resilience to extreme weather;
3. Promote water-saving agricultural technologies and improve agricultural resilience;
4. Strengthen ecological and environmental protection and mitigate the impact of climate change;
5. Raise public awareness of climate change and jointly address climate challenges.
Conclusion: Plan ahead and meet the challenges together
At present, the continent is in a critical period of climate change. Heavy rainfall continues in the south, drought is still developing in the north, and drought and flood may turn sharply in some areas. In the face of this complex weather situation, we must not only take precautions but also take various preventive measures; We should also be prepared for danger in times of peace, take a long-term view, and jointly address the challenges brought about by climate change.
There are unpredictable circumstances in the sky, and people have uncertain frontiers. Let's work together to build a safer and more resilient home. Whether it is in the face of torrential rain and floods, or high temperatures and droughts, we will calmly cope with the test of nature with a more positive attitude and scientific methods.
