The internal structure and microphysical properties of a rainband of Typhoon Kong-Rey (TY), which occurred in 2018, and of the rainfall system indirectly affected by the typhoon (IA) that passed through the southern part of the Korean Peninsula in October 2018, were analyzed by operational S-band weather radars and particle size and velocity (PARSIVEL) disdrometers.

The height of maximum intensity (H_c in km) of the IA was located at an elevation of ~ 7.5 km; moreover, in the TY regime, the column maximum (C_max in dBZ) continuously increased up to 45 dBZ at all observation sites, while H_c decreased to 5 km. The IA showed hardly any increase in temperature during precipitation, differently from the TY.

In the TY, the maximum fall velocity (V_max) of raindrops with maximum diameters (D_max) comprised between 2 and 3 mm was about 1 m s⁻¹ lower than that of drops during precipitation derived from the typhoon's indirect impact. Convective precipitation in the IA presented the following raindrop size distribution (DSD) characteristics within an interval of 18 h (from 21:00 local standard time (LST) on 4 October to 15:00 LST on 5 October): the mass-weighted mean diameter (D_m) and the logarithmic normalized intercept parameter (logN_w) were comprised between 1.3 and 1.5 mm and 3.8–4.3, respectively. However, TY showed large temporal variation within an interval of 15 h: D_m and logN_w ranged between 1.2 and 2.9 mm and 2.9–4.6, respectively. Additionally, at rainfall rates (R) of 5–15 mm h⁻¹, the shape parameter (μ) of the IA varied between 4 and 7, while that of the TY between 2 and 10.

2018年发生的台风孔雷（TY）雨带的内部结构和微物理性质，以及2018年10月通过朝鲜半岛南部间接受台风（IA）影响的降雨系统，通过运行的S波段天气雷达和粒径和速度（PARSIVEL）测速仪进行了分析。

IA的最大强度高度（_Hc，以千米为单位）位于〜7.5 km的高程处；此外，在TY模式下，所有观测点的色谱柱最大值（C _max单位为dBZ）连续增加至45 dBZ，而H _c降至5 km。与TY不同，IA在降水期间几乎没有显示出温度升高。

在TY中，最大直径（D _max）在2至3 mm之间的雨滴的最大下降速度（V _max）比台风间接影响引起的降水期间的下降的下降速度低约1 m s ^-1。在IA中，对流降水在18 h间隔（从10月4日的21:00当地标准时间（LST）到10月5日的LST 15:00）的间隔内表现出以下雨滴大小分布（DSD）特征：质量加权平均值直径（D _m）和对数归一化截距参数（logN _w）分别在1.3和1.5 mm之间以及3.8-4.3之间。但是，TY在15 h的间隔内显示出较大的时间变化：D _m和logN_w的范围分别在1.2和2.9毫米以及2.9-4.6之间。此外，在5-15 mm h ^-1的降雨率（R）下，IA的形状参数（μ）在4到7之间变化，而TY的形状参数在2到10之间变化。
