Encountering and traveling during Qingming Festival, guarding and sweeping the safe path of spring outings

Qingming Festival combines both natural and cultural connotations, serving as both a natural solar term and a traditional ancestral worship festival. During the Qingming Festival in early April, people go out to worship and go for outings. However, the complex weather conditions and potential safety risks during this period have brought many challenges to travel.

During the Qingming Festival, cold and warm air frequently intersect. The warm and humid air flow in the south is gradually strengthening and advancing northward, while the cold air in the north has not completely receded. When cold and warm air meet, warm and humid air flows up under the lifting of cold air, causing water vapor to quickly condense and form rainfall. This is the origin of the phrase 'rain falls one after another during the Qingming Festival'. At the same time, as the point of direct sunlight moves northward, the amount of solar radiation received by the ground increases, the temperature rises, and atmospheric convection becomes more intense, making the weather more variable.

Affected by the convergence of cold and warm air, many areas in China experience cloudy and rainy weather during Qingming Festival, with intermittent precipitation and high air humidity. This weather greatly affects travel convenience, reduces visibility, and poses safety hazards to transportation. Wet and slippery roads can easily cause vehicles to lose control and pedestrians to slip and get injured. Moreover, continuous rainfall may also trigger geological disasters such as landslides and mudslides, posing a serious threat to the safety of people conducting mountain sweeping and hiking activities.

In addition to the risks brought by weather, the hidden dangers of forest fires during the Qingming Festival should not be underestimated. The meteorological level of forest fire risk is divided into five levels based on the weather conditions of forest fire risk, the degree of flammability of combustibles in the forest, and the risk of forest fire spread and disaster: Level 1 low fire risk, weather conditions are difficult to trigger forest fires; The second level has a relatively low fire risk, making it less likely to cause forest fires; Level 3 moderate fire risk, more likely to cause forest fires; Level 4 high fire risk, highly likely to cause forest fires, and the spread of the fire is fast; Level 5 extremely high fire risk, combustibles in the forest are highly flammable, and the fire spreads rapidly, making firefighting extremely difficult.

During the Qingming Festival, some areas experience sparse precipitation, rising temperatures, and a dry climate. In addition to the traditional customs of burning paper money and setting off firecrackers during festivals, once encountering high fire risk weather, sparks of fire may trigger forest fires.

Faced with the hidden dangers of forest fires, Dyuan products play an important role with advanced meteorological monitoring technology and big data analysis algorithms. It can collect real-time meteorological data such as temperature, humidity, wind speed, precipitation, etc., and combine multi-source data such as satellite remote sensing images and geographic information to accurately monitor and predict forest fire risk meteorological levels. Through in-depth analysis of these data, Dyuan products can predict the changing trend of forest fire risks in advance and issue fire warning information in a timely manner.

Taking the eve of Qingming Festival in 2024 as an example, Dyuan products monitored that the forest fire risk meteorological level in a certain mountainous area continued to rise, reaching a high fire risk level of four, and immediately issued a warning. After receiving the warning, the local forestry department quickly strengthened the management of personnel entering the mountains, set up fire inspection stations at the entrance of the forest area, and strictly prohibited carrying fire into the mountains, successfully preventing the occurrence of forest fires.

In order to ensure the safety of Qingming Festival, people need to make corresponding preparations before and during their travels. When sweeping graves, one should actively choose civilized methods of worship, try to avoid burning paper money and setting off firecrackers, and use environmentally friendly methods such as offering flowers and planting trees to express grief. If traditional ritual sweeping activities must be carried out, they must be carried out in designated areas and firefighting tools must be prepared in advance. After the ritual, be sure to carefully check to ensure that the fire is completely extinguished.

Before going out for an outing, pay close attention to the weather forecast and prepare suitable clothing and rain gear according to the weather. When driving, check the condition of the vehicle in advance, plan the route, and avoid sections that are prone to geological disasters. At the same time, carry necessary medicines and food with you to deal with emergencies.

To summarize

During the Qingming Festival, by understanding the characteristics and causes of the weather in early April, mastering the knowledge of forest fire danger meteorological classification, paying attention to grave sweeping precautions and preparing for going out, and using advanced monitoring and prediction technologies such as Dyuan products, we can effectively prevent various risks, ensure safe travel during the Qingming Festival, and spend a civilized, healthy, and safe Qingming Festival.
