On July 20, 2024, Typhoon "Gemei" formed in the ocean east of the Philippines and gradually developed and strengthened into the first super typhoon of the year. Under the unified deployment of the Comprehensive Observation Department of the China Meteorological Administration, the Shanghai Meteorological Administration organized business units, universities and scientific research institutes to set up a special team to carry out integrated experiments of "earth-sea-air-sky" multi-method collaborative observation and forecasting services. After receiving the task, Qingdao Leice Transient Technology Co.,Ltd. responded quickly and immediately organized a "wind chasing" service team and rushed to multiple target observation sites in Fujian with radar equipment to carry out the deployment of fixed and mobile wind measurement lidar equipment. and data observation and analysis, and successfully completed the typhoon tracking and observation task, which won unanimous praise from all parties.
The moving path of Typhoon No. 202403 "Gemei"
Radium Core Fixed and Mobile Wind Measurement LiDAR
Carry out typhoon tracking and observation experiments
During the typhoon, many wind measuring lidars deployed by Laser Test were in good condition. The company's on-site service team has designed targeted designs based on the meteorological department's key scientific and operational observation needs such as typhoon intensity positioning capabilities, the impact of offshore boundary layer processes on typhoon intensity changes, offshore typhoon intensity change forecasts, and the microphysical mechanism of offshore typhoon heavy precipitation. The lidar observation mode and configuration related parameters effectively obtain high spatial and temporal resolution real-time stereoscopic observation data of typhoon transit.
The implementation of this integrated test of observation and forecasting operations has effectively facilitated the acquisition of typhoon fine structure, research on maintenance mechanisms, and analysis of the formation mechanism of extreme precipitation. It has tested and strengthened the application capabilities of lidar and other profile observation data in typhoon model operational forecasting. In the future, Laser Test will continue to strengthen close cooperation with relevant business departments and scientific research units, promote the construction of my country's lidar stereo observation network and its application in meteorological service guarantee, and help the rapid development of my country's meteorological industry.
