项目摘要

The coastal climate of California is profoundly affected by the ocean, which moderates its hot summers and provides moisture for much-needed winter rains. Sea surface temperature (SST) anomalies and ocean surface current anomalies, ranging from the meso-to-frontal scales of cool coastal upwelling to the regional-to-basin scales of the marine heat waves, are inherently coupled with the atmosphere. This study focuses on the fundamental coupled ocean-atmosphere feedback processes that affect the climate, weather, and upwelling along the coast. The project will use numerical models of the coupled ocean-atmosphere system to improve understanding of the ocean-atmosphere interactions, including with land and mountains, for coastal California. In addition, it will examine the effects on climate of coastal California under projected future greenhouse-gas-forced changes.This project will quantify the effects of ocean-atmosphere boundary layer coupling on California coastal regions using a series of regional high-resolution coupled ocean-atmosphere model simulations, including full ocean-atmosphere coupling and well-resolved orography and land-sea distribution. These will include ensembles of 10-year long runs forced by observed current climate and projected future climate boundary conditions, as well as ensembles of runs initialized under observed marine heat wave conditions. The model runs will be used to study how the statistics of daily, intraseasonal and interannual variability in the atmosphere and the oceanic upwelling field, are affected by the anomalous ocean-atmosphere conditions associated with eddies, fronts, and extreme SST anomalies, and assess how they may be altered by changes in large-scale atmospheric and oceanic drivers associated with global warming.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
加州的沿海气候深受海洋的影响,海洋缓和了炎热的夏季,并为急需的冬季降雨提供了水分。海表温度(SST)异常和海洋表面流异常,从中尺度到锋面尺度的冷海岸上升流到区域尺度到盆地尺度的海洋热浪,都与大气有着内在的耦合。这项研究的重点是基本的耦合海洋-大气反馈过程,影响气候,天气和上升流沿着海岸。该项目将利用海洋-大气耦合系统的数值模型,增进对海洋-大气相互作用的了解,包括对加州沿海地区与陆地和山脉的相互作用的了解。此外,该项目还将研究在预测的未来温室气体强迫变化下对加州沿海气候的影响,该项目将利用一系列区域高分辨率海洋-大气耦合模式模拟,包括完整的海洋-大气耦合和高分辨率地形和陆地-海洋分布,量化海洋-大气边界层耦合对加州沿海地区的影响。这些将包括由观测到的当前气候和预测的未来气候边界条件强制进行的10年长期运行的集合,以及在观测到的海洋热浪条件下初始化的运行集合。模式运行将用于研究大气和海洋上升流场的日变化、季节内变化和年际变化的统计数据如何受到与涡旋、锋面和极端SST异常有关的异常海洋-大气条件的影响,而他们的改变,是怎样改变的呢?该奖项反映了NSF的法定使命,并通过使用基金会的智力价值进行评估,被认为值得支持和更广泛的影响审查标准。
