英文摘要	Regions with high ice water content (HIWC),composed of mainly small ice crystals, frequently occurover convective clouds in the tropics. Such regions can havemedian mass diameters (MMDs) <300 μm and equivalentradar refiectivities <20 dBZ. To explore formation mecha-nisms for these HIWCs, high-resolution simulations of trop-ical convective clouds observed on 26 May 2015 during theHigh Altitude Ice Crystals - High Ice Water Content (HAIC-HIWC) international field campaign based out of Cayenne,French Guiana, are conducted using the Weather Researchand Forecasting (WRF) model with four different bulk mi-crophysics schemes: the WRF single-moment 6-class micro-physics scheme (WSM6), the Morrison scheme, and the Pre-dicted Particle Properties (P3) scheme with one- and two-ice options. The simulations are evaluated against data fromairborne radar and multiple cloud microphysics probes in-stalled on the French Falcon 20 and Canadian National Re-search Council (NRC) Convair 580 sampling clouds at dif-ferent heights. WRF simulations with different microphysicsschemes generally reproduce the vertical profiles of temper-ature, dew-point temperature, and winds during this eventcompared with radiosonde data, and the coverage and evolu-tion of this tropical convective system compared to satelliteretrievals. All of the simulations overestimate the intensityand spatial extent of radar reflectivity by over 30% abovethe melting layer compared to the airborne X-band radar re-flectivity data. They also miss the peak of the observed icenumber distribution function for 0.1< Dmax <1 mm. Eventhough the P3 scheme has a very different approach repre-senting ice, it does not produce greatly different total con-densed water content or better comparison to other observa-tions in this tropical convective system. Mixed-phase micro-physical processes at -10 °C are associated with the over-prediction of liquid water content in the simulations with theMorrison and P3 schemes. The ice water content at -10 °C increases mainly due to the collection of liquid water by iceparticles, which does not increase ice particle number butincreases the mass/size of ice particles and contributes togreater simulated radar reflectivity. © 2021 Copernicus GmbH.
