在以色列-埃及边界沙丘地区的卫星图像上观察到一个非常奇怪的热异常。植被覆盖率较高的以色列一侧白天的地表温度明显高于裸露沙面较多的埃及一侧。沙丘区地表热异常这一奇特现象,有待揭示一系列谜题。在以色列-埃及边界沙丘地区的卫星图像上观察到一个非常奇怪的热异常。植被覆盖率较高的以色列一侧白天的地表温度明显高于裸露沙面较多的埃及一侧。沙丘区地表热异常这一奇特现象,有待揭示一系列谜题。Why does the thermal anomaly occur in the region? Is it a natural phenomenon or a man-made one? How does the anomaly change in the region? How does it vary among different seasons of the year? Are there any regularityin the spatial distribution and seasonal variation? What is the mechanism behind the occurrence of the phenomenon? The objective of this study is to uncover the mystery behind the thermal anomaly through a thorough examination from remote sensing analysis,ground truth measurement, numerical simulation and micro-meteorological modeling.为什么该地区会出现热异常?是自然现象还是人为现象?该地区的异常变化如何?在一年中不同的季节它是如何变化的?空间分布和季节变化有规律吗?这种现象发生的机制是什么?本研究旨在透过遥感分析、地面真值测量、数值模拟及微气象模拟等方法,揭示热异常背后的奥秘。
