On June 18, Meiyu front rainstorm joint scientific experiment in the middle and lower reaches of the Yangtze River initiated the first aircraft observation. The plane took off from the Three Gorges airport in Yichang, Hubei, traversed meiyu front precipitation cloud cluster and carried out space-based observation. In the meanwhile, rainstorm field scientific experiment base in the middle and lower reaches of the Yangtze River of China Meteorological Administration (CMA) in Xianning, Hubei, as well as observation base in Jiangling, Jingzhou conducted joint observation through myriad ground observation facilities, and coordinated in capturing the macro environment of meiyu front, cloud microphysics, and precipitation observation data.

At 10:10 a.m. on June 18, the plane took off from the airport. Members from the experiment project recorded observation data on the plane.

On June 18, after the plane left from the rainstorm field scientific experiment base in the middle and lower reaches of the Yangtze River, the team cast off the sounding balloon.

This experiment will persist into the entire plum rain season. It aims to explore Meiyu front precipitation mesoscale systemic dynamics and thermal structure, as well as hydrometeor structure and microphysical features of rainstorm cloud cluster, and reveal the mechanism of water vapor and environmental field conditions affecting precipitation cloud emergence and evolution through integrate and apply multi-source observations. The experiment is expected to elevate heavy rainfall prediction technology and capacity of China via ground-space-celestial-based joint observations targeted at Meiyu front precipitation.

On June 15, in observation base in Jiangling, Jingzhou, the team carried out debugging of the newly installed two-dimensional video raindrop spectrograph.

The research results of the experiment will be applied in Meiyu front heavy rainfall research and services for the flood season. (Jun. 22)
