摘要

本研究探讨了热带风暴 "马立克斯 "的特征和发展情况。"马立克斯 "是西南季风爆发期间在南海西北部形成的一个热带气旋特例。研究利用观测数据和预报产品进行了详细分析。地面观测、雷达风廓线、飞机数据和卫星产品被用来评估 "马利克西 "的风结构,揭示了多个环流中心和大风。研究了垂直风廓线、暖核心结构、风浪以及海温和盐度对 "马利克西 "加强的影响。在预报方面,基于人工智能的模式在预测 "马利克西 "的初期发展方面优于传统的数值天气预报(NWP)模式,但两者都难以捕捉系统向内陆移动时强风的持续性。高分辨率的 NWP 模拟被用来研究香港国际机场周围由地形引起的风的变化,揭示了山区尾流效应以及风和湍流的不均匀分布。这些发现为预报和监测此类热带气旋所面临的挑战提供了启示,并强调了在易受此类系统影响的海岸线加强观测平台和预报工具的必要性。

A Rare Tropical Cyclone Associated With Southwest Monsoon Over the Northern Part of the South China Sea—Tropical Storm Maliksi

A Rare Tropical Cyclone Associated With Southwest Monsoon Over the Northern Part of the South China Sea—Tropical Storm Maliksi

This study examines the characteristics and development of Tropical Storm Maliksi, which is a special case of tropical cyclone developed in the northwestern part of the South China Sea during a southwest monsoon outbreak. Detailed analyses were conducted using observational data and forecast products. Surface observations, radar wind profilers, aircraft data, and satellite products were used to evaluate Maliksi's wind structure, revealing multiple circulation centers and gale force winds. Vertical wind profiles, warm core structure, wind waves, and the influence of sea temperatures and salinity on Maliksi's intensification were investigated. Regarding forecasting, AI-based models outperformed conventional numerical weather prediction (NWP) models in predicting Maliksi's initial development, though both struggled to capture the persistence of strong winds as the system moved inland. High-resolution NWP simulations were employed to examine terrain-induced wind variability around Hong Kong International Airport, revealing the mountain wake effect and uneven wind and turbulence distribution. These findings provide insights into the challenges of forecasting and monitoring such tropical cyclones, and highlight the need for enhanced observational platforms and forecasting tools along coastlines vulnerable to these systems.
