云的数值建模与能够求解基本动力学方程的离散版本的计算机一样古老。 With the limited memories and computer power available in the 1960s and 1970s, most modelers employed two-dimensional slab or axisymmetric approximations to study convective dynamics (e.g., Lilly 1962; Ogura and Charney 1962; Orville 1968; Takeda 1971; Wilhelmson and Ogura 1972; Hane 1973; Soong and Ogura 1973; Schlesinger 1973; Soong 1974).平板模型代表了在有或没有垂直风剪切的环境中形成的无限长对流频段的对流生长，而轴对称模拟的对流频段被限制在无剪切环境中。 However, as computer power grew and vector computers were developed (e.g., the CRAY 7600 and the succeeding CRAY computers; Kaufmann and Smarr 1993), it became possible to solve the three-dimensional equations of motion on relatively coarse-mesh grids (e.g., Steiner 1973; Deardorff 1972; Wilhelmson 1974; Schlesinger 1975; Klemp and Wilhelmson 1978b).
Numerical modeling of clouds is as old as computers capable of solving discrete versions of the fundamental dynamical equations. With the limited memories and computer power available in the 1960s and 1970s, most modelers employed two-dimensional slab or axisymmetric approximations to study convective dynamics (e.g., Lilly 1962; Ogura and Charney 1962; Orville 1968; Takeda 1971; Wilhelmson and Ogura 1972; Hane 1973; Soong and Ogura 1973; Schlesinger 1973; Soong 1974). The slab models represented the convective growth of infinitely long convective bands forming in environments with or without vertical wind shear, while the axisymmetric simulations were constrained to shearless environments. However, as computer power grew and vector computers were developed (e.g., the CRAY 7600 and the succeeding CRAY computers; Kaufmann and Smarr 1993), it became possible to solve the three-dimensional equations of motion on relatively coarse-mesh grids (e.g., Steiner 1973; Deardorff 1972; Wilhelmson 1974; Schlesinger 1975; Klemp and Wilhelmson 1978b).
