 摘要： Along with various human production or consumption activities, large-scale air pollution, water pollution, noise, land subsidence and other public nuisances that are harmful to human health and the living environment have emerged. With the emergence and rise of environmental awareness among the people of Taiwan, in the face of the increasingly deteriorating environment, Taiwan has taken a series of measures. First of all, Article 9 of the Administrative Litigation Law first stipulates public interest litigation; then, Article 34 of the Basic Law on the Environment clearly stipulates the important documents for public interest litigation. In this paper, it is held that environmental maintenance and improvement is the responsibility of every citizen, not just that of the government. On the path of environmental public interest litigation, every citizen should have the right mindset and response strategies.

 摘要： In this paper, different stands in Xianzhong Nursery of Pingjiang were selected as the research object to study the runoff generation and soil loss characteristics of different stands. The results showed that the annual surface runoff of each model in Pingjiang was between 50.50 and 70.38 mm, and the annual surface runoff of each stand decreased with years. There was no significant difference in the annual runoff between each stand, nor between each stand and its control. There were significant differences in soil erosion modulus among the models, and the number ranged from 139.20 to 197.79 t/(km2▪y).

 摘要： Using conventional observation data and Guilin Doppler weather radar data, the atmospheric circulation situation, environmental conditions and mesoscale characteristics of convective storms during the severe convective weather process in Guilin, Guangxi on April 19, 2025 were analyzed in detail. The results showed that the severe convective process was dominated by short-term heavy rainfall, accompanied by thunderstorm and gale. This was a strong convective weather process in the warm region. On the south side of warm shear line, with the south branch fluctuation moving eastward, strong convection occurred near the surface convergence line. With the establishment of low-level jet at night, organized development of convection system was obtained. The environmental conditions showed unstable stratification, inversion layer, small convective effective potential energy, large K value and strong wind shear, and the inverted V-shaped structure was at low level. The convective storm that produced short-term heavy rainfall presented as low centroid precipitation echo. The mixed convection in Xinlong, Baishou, Yongfu was caused by heavy rainfall supercell and presented as high centroid precipitation echo, with weak echo area, bounded weak echo area and medium-intensity mesocyclone.

 摘要： In this paper, Wuzhou City of Guangxi was taken as the research object. Through the design of a climatic data warehousing system, the decoding methods of surface meteorological data and their application in the management of climatic data were explored. Based on the parsing technology of the monthly report of surface meteorological records (A-file), the design of Wuzhou climatic data warehousing system was realized, completing the precise extraction and database construction of observational elements such as regional temperature, wind direction, and weather phenomena. Based on this system, the meteorological data in 2024 were analyzed, and the probabilistic characteristics of dominant wind direction in Wuzhou (northeast wind accounting for the largest proportion), the spatiotemporal distribution patterns of extreme temperatures (annual extreme high temperature of 37.1 ℃ in August and extreme low temperature of 1.9 ℃ in January), and the general climatic overview of Wuzhou City (annual precipitation 3.2% higher than the standard value) were revealed. The research shows that climate change has a significant impact on agricultural production and economic development in Wuzhou City, and the construction of a reasonable climatic data database is of great significance for enhancing professional meteorological service capabilities in the context of climate change. This study not only provides a scientific basis for the economic development of Wuzhou region, but also offers reference ideas for other regions to cope with regional climate adaptation planning.

 摘要： Based on the observation data of meteorological observation stations in Jining City during 1970-2024, MK mutation test and principal component analysis (PCA) were used to study the evolution characteristics of urban heat island intensity (UHII) and the contribution rate of various influencing factors in Jining City over the past 55 years. The results show that from 1970 to 2024, the UHII in Jining City generally rose at a rate of 0.1 ℃/10 a. On the interannual scale, the correlation between temperature and UHII was most significantly positive. On the seasonal scale, there was a strong negative correlation between wind speed and UHII. PCA reveals that temperature had a significant positive impact on the increase of UHII in Jining City.

 摘要： Typhoons, as strong convective systems, can excite multi-scale atmospheric gravity waves that travel long distances, and play an important role in momentum and energy transmission between the middle and upper atmosphere. In this paper, the research progress in the observation techniques, generation mechanism and propagation characteristics of typhoon-induced gravity waves were systematically reviewed. These studies show that based on the combined application of ground-based and space-based observation (sounding balloons, airglow imaging, and satellite remote sensing) and reanalysis data (such as ERA5), with the aid of ray tracing theory and numerical simulation technology, the mechanism of typhoon induced gravity waves and its dynamic characteristics in the middle and upper atmosphere have been better revealed. At present, there are still some insufficiencies in the fields of propagation path tracking of gravity waves, terrain multi-scale effect modeling and parameterization of inertial gravity waves, which need to be further studied in the future.

 摘要： Based on the number of asthmatic children in the Children's Hospital of Yulin City, the monitoring data of daily pollen concentration, and routine meteorological and environmental monitoring data of Yulin City from 2020 to 2022, the meteorological and environmental conditions of a thunderstorm asthma event in Yulin City in northern Shaanxi on September 9, 2022 were analyzed. The results show that the strong convective weather was accompanied by a strong thunderstorm, lightning, gusts, short-time heavy precipitation and small hail, and the convective activity lasted for nearly 7 h. The short-term abrupt change of allergenic substances such as artemisia pollen caused by lightning, gusts and precipitation, the sudden drop in temperature, the inversion near the surface and the stimulation of cold air were the key meteorological conditions for the subsequent outbreak of asthma. In early September in 2022, the daily average pollen concentration in Yulin City was up to 1 067.9 particles/1 000 mm2, which was 113.3% and 41.2% higher than that of the same period in 2021 and 2020, respectively. The day before the thunderstorm, the pollen concentration soared to 2 680 particles/1 000 mm2, reaching the maximum of the year. The synergistic effect of the thunderstorm event and the sharp increase in pollen concentration on the previous day provided the background of heavy pollen pollution for this outbreak of thunderstorm asthma. O3 concentration was consistently high on the day of thunderstorm and the day before, and the peaks of O3 and PM10 concentration appeared subsequently in the afternoon of the day, which became the background of air pollution for the asthma outbreak.

 摘要： It is an important standard to judge the flood disaster in the basin whether the rainfall at the flood-inducing interface is reached. In this paper, the Xin'anjiang model, Topmodel model and SCS model were selected to calculate and compare the rainfall at the flood-inducing interface in the Zhanghe Reservoir basin in Hubei Province. The results showed that average relative error and average absolute error of Xin'anjiang model were -3.36% and -21.46×105 m3, which were the minimum, followed by Topmodel model with 5.72% and 26.22×105 m3, SCS model with 11.33% and 58.13×105 m3. The minimum absolute error of the three hydrological models in calculating the rainfall at the critical interface was 3.26 mm, while the maximum was 49.24 mm. When the initial water level exceeded 120 m, the difference among the three models in calculating the rainfall at the critical interface became more and more obvious. When the reservoir water level was lower than 120 m, it mainly referred to the calculation results of Xin'anjiang model. When the reservoir water level was higher than 120 m, it mainly referred to the calculation results of Topmodel model. The research conclusion can provide reference for small and medium-sized basins selecting hydrological model to calculate the rainfall at the flood-inducing interface.

 摘要： Kangbao County is located in the northwest of Bashang in Hebei Province, which is a sub-arid area in the middle temperate zone, with a cold and arid climate and frequent disastrous weather. The meteorological data of Kangbao County Meteorological Station from 1994 to 2023 were selected, and the meteorological elements such as air pressure, temperature, precipitation, wind, relative humidity, sunshine, thunderstorm, hail, gale, rainstorm, fog, and snow cover were counted. The climate background analysis and high-impact weather analysis were carried out in combination with the topographic characteristics, geographical location, and climate characteristics. The results of meteorological sensitivity survey in the park showed that industries such as food, agriculture and new energy are very sensitive to temperature. During the visit to the enterprises in the park, it was found that heavy precipitation, snow, strong winds and hail had a great impact on many industries, and it was recommended to carry out long-term planning and reasonable design of buildings. It should pay close attention to forecasts and early warnings, formulate emergency plans for high-impact weather defense, and actively take preventive measures.
