Microphysical features of typhoon and non-typhoon rainfall observed in Taiwan, an island in the northwestern Pacific

Abstract. Information about the raindrop size distribution (RSD) is vital for comprehending precipitation microphysics, improving rainfall estimation algorithms, and appraising erosivity. Previous research has revealed that RSD exhibits diversity with geographical location weather type, which leads to assessment of region weather-specific RSDs. Based on long-term (2004 2016) disdrometer measurements in northern Taiwan, this study attempts demonstrate aspects summer seasons were bifurcated into two conditions, namely typhoon (TY) non-typhoon (NTY) rainfall. The results show a higher concentration small drops lower large-sized TY compared NTY rainfall, behavior persisted even after characterizing RSDs different rate classes. expressed gamma parameters mass-weighted mean diameter (Dm) normalized intercept parameter (Nw) values than Moreover, sorting these conditions (TY rainfall) stratiform convective regimes larger Dm empirical relations used valuation (Z–R, Dm–R, Nw–R) kinetic energy (KE–R KE–Dm) enumerated they exhibited profound between conditions. Attributions variability thermodynamical microphysical processes are elucidated aid reanalysis, remote sensing, ground-based data sets.
