Many researches showed that the distribution of air pollution and the timing, strength of precipitation would be affected by land-sea breeze in Taiwan. Land-sea breeze would affect the distribution of precipitation coupling with large-scale environmental wind. Most of studies of land-sea breeze were based on the results from model simulation, on the other hand, the observation evidences are limited. Therefore, to resolve the vertical structure of atmosphere by using Unmanned Aircraft System (UAS) might be a new direction. Advantages of UAS includes a higher payload and higher spatial-temporal resolution as compared with traditional sounding balloons. The proposed project will use UAS to observe atmospheric profile and study the typical diurnal change of land-sea breeze under weak synoptic weather condition in southern Taiwan. The new strategy of UAV observation is hoping to be a consultation of weather monitoring and weather forecast in the future.For the detailed proposal, first of all, our team are going to analyze historical observation data, reanalysis data, and modeling data to examine the features of land-sea breeze over southern Taiwan, and make a better observing strategies according to the features. Three spots synchronous day-night UAV observations will be carried over Tainan during intensive observing periods. Integration analysis of UAV, sounding balloon, and ground station observation data, we can get the whole picture of the land-sea breeze over southern Taiwan under weak-synoptic weather condition. Our team will improve observing strategies continuously, and perform another IOP in 2022 based on the experience in 2021. Finally, we would like to characterize the features of the land-sea breeze under weak-synoptic weather condition, and to summarize its impacts on regional air quality and precipitation.
