0933414GonzalezThe main objective of this research is to identify asymmetric warming-cooling trends in coastal areas and the associated impacts on energy demands. Recent results of observational studies have suggested an asymmetric warming in coastal California not captured by global scale climate models or analyses. As a consequence, for this research it has been hypothesized that climate change impacts at inland sites in California have increased summer daytime horizontal temperature gradients, which have increased the strength and frequency of cool summer marine sea-breeze flows into heavily populated and highly polluted California coastal plains, which in turn decrease the demand for electrical energy for cooling. To test this hypothesis, the unique thermal surface gradient will be studied in detail along California coastlines and the specific implications for changes in average and peak electricity demands will be investigated. The approach will be to investigate the changes in both climatological degree days (for both heating and cooling) and in heat waves (in terms of frequency and severity), and to correlate these changes with topography, sea breeze patterns, urban centers, and distance from the coast. The climatological analysis will be correlated with existing energy demand information from electric and gas utilities in the state to determine spatial and temporal trends. The climatological analyses will be projected into the future (50+ years) with a mesoscale atmospheric model, which will be driven by downscaled information from Global Circulation Models based on IPCC scenarios. The modeling will address the relative effects of global warming (different scenarios) and land use changes, as reflected in changes of energy variables (degree days, peak electricity and gas demands). The project is a joint collaboration of two minority serving universities (CCNY and San Jose State University) and Lawrence Berkeley National Laboratory.

0933414Gonzalez这项研究的主要目的是确定沿海地区的不对称变暖冷却趋势以及对能源需求的相关影响。 观察性研究的最新结果表明，全球气候模型或分析未捕获的沿海加利福尼亚州的不对称变暖。 结果，对于这项研究，人们已经假设，加利福尼亚州内陆场地的气候变化影响增加了夏季白天的水平温度梯度，这增加了凉爽的夏季海洋海上海上冻结流动的强度和频率，成为人口稠密的加利福尼亚沿海平原，这又减少了对冷却的需求。 为了检验这一假设，将研究沿加利福尼亚海岸线的详细研究独特的热表面梯度，并将研究对平均电力和峰值电力需求变化的具体意义。 该方法将是研究气候度的日子（用于加热和冷却）和热浪（就频率和严重程度而言）的变化，并将这些变化与地形，海风模式，城市中心以及距离海岸的距离相关联。 气候分析将与该州电力和天然气公用事业的现有能源需求信息相关，以确定空间和时间趋势。 气候分析将通过中尺度大气模型投射到未来（50多年）中，该模型将由基于IPCC场景的全球循环模型的缩小信息驱动。 该建模将解决全球变暖（不同的场景）和土地利用变化的相对影响，如能量变量的变化（度数天数，峰值电力和气体需求）所反映。 该项目是两名少数派服务大学（CCNY和圣何塞州立大学）和劳伦斯·伯克利国家实验室的联合合作。
