论文摘要
事实证明，云的形状对于对它们进行分类至关重要。我们对天气天气云的图像的分析表明，除了湍流外，它们是由自组织的批判性（SOC）驱动的。我们的观察结果产生的指数支持云的事实，当投影到两个维度（2D）时，与$ c = 0 $ cft的2D湍流相比，与$ c = -2 $保形场理论（CFT）相吻合。通过使用Navier-Stokes方程，扩散方程和耦合MAP晶格（CML）的组合，我们成功模拟了云形成，并获得了相同的指数。
The shape of clouds has proven to be essential for classifying them. Our analysis of images from fair weather cumulus clouds reveals that, besides by turbulence they are driven by self-organized criticality (SOC). Our observations yield exponents that support the fact the clouds, when projected to two dimensions (2D), exhibit conformal symmetry compatible with $c=-2$ conformal field theory (CFT), in contrast to 2D turbulence which has $c=0$ CFT. By using a combination of the Navier-Stokes equation, diffusion equations and a coupled map lattice (CML) we successfully simulated cloud formation, and obtained the same exponents.
