Graphical Abstract Published

Plain Language Summary: Using long-term laser disdrometer data, we investigated the raindrop size distribution (RSD) characteristics of Meiyu precipitation in Mount Lushan, eastern China. Statistical properties for RSD parameters in mountainous site of different rain rates and rain types are presented. Parameterization schemes for RSD description and precipitation estimation for Meiyu precipitation are derived. The results show that the mountainous topography plays an important role in reshaping the characteristics of RSD and the physical processes of precipitation.

Highlights:

• Long-term laser disdrometer observed RSD data are used to investigate Meiyu precipitation in a mountainous site.
• The relations between gamma distribution parameters (μ-Λ), and for quantitative precipitation estimation (Z-R) are derived.
• A specific RSD subset with high Nw (log10Nw>4.5) is assessed, which is caused by mountainous topography induced continuous in-cloud precipitation.
• The mountainous topography plays an important role in reshaping the characteristics of RSD and the physical processes of precipitation.
