Technical Field

Background
In the current production and life, bad weather often has adverse effects on industrial and agricultural production, transportation, electric power, human health and the like, wherein the narrow valley region is most seriously affected by bad weather, and the weather conditions of the narrow valley region are usually worse and unstable than those of plain regions due to the special properties and high altitude of the narrow valley region, so that it is important for residents, tourists and related industries in the narrow valley region to know and adapt to the bad weather, and proper precautions must be taken to enhance safety consciousness and ensure personal safety and sustainable development of local environment.
However, in the weather prediction in the current narrow valley region, the following difficulties still exist:
1. the topography of the narrow valley area is complex and changeable, and a large number of mountain, canyon, plateau and other landform features exist. These topographical factors have an important impact on the formation and changes of the meteorological system, making meteorological predictions more difficult. Due to irregularities in the terrain, the distribution of air currents and precipitation may also be affected, leading to a diversity of local weather phenomena.
2. Weather changes in narrow valley areas are very rapid and can change drastically in a short period of time. Due to the characteristics of mountain blocking and high altitude, the climate conditions are often extremely variable, and the weather system can rapidly move and evolve.
3. Meteorological observation networks in narrow valley areas are relatively scarce compared to plain areas. Deployment of equipment such as weather station settings, weather radars, satellite coverage, and the like in narrow valley areas is difficult, resulting in rarefaction and incompleteness of the observed data. This presents a certain difficulty for weather prediction, limiting accurate grasp of weather in narrow valley areas.
4. The altitude of the narrow valley area is higher, the air temperature is generally lower, and special environmental conditions such as thin air, high pressure and the like exist. These factors can affect the formation and evolution of the weather system and can also pose challenges to the applicability of the weather prediction model.
