风场仿真模型数据

在气象研究和雷达性能评估领域，为了深入探究平原地区典型风切变风场的特性，借助计算流体动力学（CFD）技术开展了一系列工作，成功建立了6种具有代表性的风切变风场，分别为海陆风、微下击暴流、冷暖锋风场、侧风、低空急流以及双微下击暴流风场。CFD技术作为一种强大的数值模拟方法，基于流体力学的基本原理，通过计算机算法对流体的流动进行数值求解。在本研究中，利用CFD技术建立这6种风场模型，因平原地区的风切变风场受多种因素影响，其流动特性复杂。例如，海陆风是由于海陆热力性质差异引起的，白天陆地升温快，空气上升，海洋上的空气流向陆地；夜晚则相反。而微下击暴流是一种强烈的下沉气流，具有很强的破坏性。通过CFD技术，我们能够精确地模拟风场的形成、发展和演变过程。

Within the domains of meteorological research and radar performance assessment, to gain in-depth insights into the characteristics of typical wind shear wind fields over plain regions, a series of studies were conducted employing computational fluid dynamics (CFD) techniques, and six representative wind shear wind field models were successfully established, including sea-land breeze, microburst, cold/warm front wind field, crosswind, low-level jet, and dual-microburst wind fields. As a powerful numerical simulation method, CFD is based on the fundamental principles of fluid mechanics, and numerically solves fluid flow via computer algorithms. In this study, the six wind field models were established using CFD techniques, given that wind shear wind fields over plain regions are influenced by multiple factors and exhibit complex flow characteristics. For instance, sea-land breeze is caused by thermal property differences between land and sea: during the daytime, land heats up faster, leading to air ascent, while air over the sea flows towards the land; the opposite pattern occurs at night. Meanwhile, a microburst is a severe downdraft with strong destructive potential. With CFD techniques, we can accurately simulate the formation, development, and evolution processes of wind fields.
