The genesis and evolution of a sea-breeze front associated with a shallow convection episode at Fuerteventura Island (Canaries archipelago) are investigated using the Weather Research and Forecasting (WRF) numerical model. Three local and two non-local planetary boundary layer (PBL) parametrization schemes are used, and results of the numerical simulations are compared with observations from the local meteorological surface station network. Statistical analysis shows a good agreement between simulations and measurements, in particular for the 2-m temperature. These results are used in choosing the final PBL scheme and its coupled surface-layer scheme, which is used to simulate the daytime period of the sea-breeze development and weakening. During this episode, a sea-breeze front moved inland against a prevailing offshore flow 3 h after sunrise, colliding with a downslope flow near the centre of the island. The convergence of both flows from opposing directions produced a strong updraft, forming shallow convection a few hours later.

西班牙加那利群岛富埃特文图拉岛海风的数值研究

使用天气研究和预报 (WRF) 数值模型研究了与富埃特文图拉岛（加那利群岛）浅对流事件相关的海风锋的起源和演化。使用三种局部和两种非局部行星边界层 (PBL) 参数化方案，并将数值模拟结果与当地气象地面站网络的观测结果进行比较。统计分析显示模拟和测量之间有很好的一致性，特别是对于 2 米的温度。这些结果用于选择最终的 PBL 方案及其耦合表层方案，用于模拟白天海风发展和减弱。在这一集中，海风锋在日出后 3 小时逆着盛行的离岸气流向内陆移动，与岛中心附近的下坡流相撞。来自相反方向的两股气流的会聚产生了强烈的上升气流，几小时后形成浅对流。
