摘要

利用观测到的雪花微物理特性，模拟了双偏振雷达变量微分反射率$(\ mathm {Z}_{\ mathm {dr}})$。粒子质量和长径比的增加对$\mathrm{Z}_{\mathrm{dr}}$的影响是相反的，这种矛盾的影响在不同的边缘条件下是不同的。利用模拟结果对雷达观测资料进行了解释，发现模拟结果与现行的环化过程假设相符。

Dual-Polarization Radar Signatures of Rimed Snowflakes

Dual-polarization radar variables, such as differential reflectivity $(\mathrm{Z}_{\mathrm{dr}})$, are simulated from observed microphysical property of snowflakes. The increases of particle mass and aspect ratio are found to have opposite effects on $\mathrm{Z}_{\mathrm{dr}}$, This contradictory effect is different in various riming condition. The results of simulation were adopted to interpret radar observations, which are found to agree with the current hypothesis of riming process.
