East Asia Mei-yu frontal heavy rain field experiments and numerical modeling research
Convener: Chunguang Cui | Co-convener: Bin Wang
The Mei-yu season, typically occurring from mid-June to mid-July, on average, contributes to 32% of the annual precipitation over the Yangtze–Huai River Valley and represents one of the three heavy-rainfall periods in China. Research on Mei-yu frontal heavy rain has achieved a substantial number of results in international studies over the past few years. With the improvements and refinement of numerical forecasting, the forecasting accuracy for Mei-yu frontal rainstorms has also been continuously enhanced. This session will focus on the scientific field experiments and numerical simulation studies of Mei-yu frontal heavy rain, showcasing how field observations can provide deeper insights into the microphysical characteristics of clouds and precipitation associated with the Mei-yu front. It will also cover how to quantitatively assess the applicability of cloud microphysics schemes in regional models, as well as how to develop cloud microphysics parameterization schemes suitable for forecasting Mei-yu front precipitation. The session expects three topics as follows:
1. Observation experiment and monitoring technology of extreme precipitation;
2. Dynamical origin and multi-scale interactions of Mei-yu front systems;
3. Development of numerical model and new technology for the prediction and projection of extreme precipitation.
