摘要
云微观物理在决定热带气旋(TC)的强度和降水方面发挥着重要作用。本研究利用 WRF(4.2 版)对台风 "梅兰蒂"(2016 年)快速加强(RI)期间进行了高分辨率数值模拟,并通过多源观测数据(包括 Cloud-Sat 和全球降水任务卫星数据)进行了验证。发现在 RI 过程中,与其他水文介质相比,冰雪颗粒含量增加最快。并非所有水文介质都持续增加。冰雪颗粒含量仅在 RI 初期增加,之后由于 RI 过程中的降水而减少。此外,海面温度(SST)敏感性实验表明,虽然随着 SST 的升高,TC 强度增加,但并不是所有的水介质都增加了。石灰华含量随着 SST 的升高而继续增加,这主要是由于在相应高度积累了更多的低温过冷水汽。雪的含量随着 SST 的升高而减少,这是因为相应高度上更强的垂直运动影响了冰晶的聚集。
Cloud Microphysical Characteristics of Typhoon Meranti (2016) during Its Rapid Intensification: Model Validation and SST Sensitivity Experiments
Cloud microphysics plays an important role in determining the intensity and precipitation of tropical cyclones (TCs). In this study, a high-resolution numerical simulation by WRF (version 4.2) of Typhoon Meranti (2016) during its rapid intensification (RI) period was conducted and validated by multi-source observations including Cloud-Sat and Global Precipitation Mission satellite data. The snow and ice particles content were found to increase most rapidly compared with other hydrometeors during the RI process. Not all hydrometeors continued to increase. The graupel content only increased in the initial RI stage, and then decreased afterwards due to precipitation during the RI process. In addition, sea surface temperature (SST) sensitivity experiments showed that, although the intensity of the TC increased with a higher SST, not all hydrometeors increased. The graupel content continued to increase with the increase in SST, mainly due to the accumulation of more lower-temperature supercooled water vapor at the corresponding height. The content of snow decreased with the increase in SST because stronger vertical motion at the corresponding height affected the aggregation of ice crystals.
