简介：二个模型基于静水力学的原始方程被建议。第一个模型仅仅是有部分粘性的原始方程，并且向在海洋和空气的大规模波浪结构是面向的。第二个模型是粘滞原始方程与光谱旋涡粘性，并且向狂暴的地球物理的流动是面向的。为两个模型，全球强壮的答案的存在和唯一被建立。为第二个模型，旋涡粘性参数趋于到零的古典原始方程的答案的答案的集中也被建立。

简介：复杂地球物理的数据的倒置总是解决多参数，非线性、多模式的优化问题。寻找最佳的倒置答案类似于当寻找食物时，在象鸟和蚂蚁那样的群观察的社会行为。在这篇文章，首先，粒子群优化算法详细被描述，并且蚂蚁殖民地算法改善了。然后，方法被用于地球物理的倒置问题的三种不同类型：(1)对噪音敏感的一个线性问题，(2)线性、非线性的问题的同步倒置，并且(3)一个非线性的问题。结果验证他们的可行性和效率。与常规基因算法相比并且退火模仿，他们有更高的集中速度和精确性的优点。与伪相比--牛顿方法和Levenberg-Marquardt方法，他们与克服局部地最佳的答案的能力更好工作。
