Numerical simulation for this event is performed using the non-hydrostatic, two-way interactive, triply nested grid mesoscale model MM5 and the structure of the inverted typhoon trough is studied. Furthermore, the formation and development mechanism of the inverted typhoon trough as well as the meso-scale vortex are discussed through the budget of vorticity equation.

However, all experiments show sparser isotherms than the observation, which implies that the physical parameterization of the ocean model still need to be improved, especially of the mixing process.

同时，8组试验也一致地表现出等温线的密集程度比实际情况稀疏，这反映了模式在物理过程，特别是混合过程的描述方面，还有值得改进的地方。

The stuff they call "water" is XYZ, and the process they call "boiling" is a process that superficially resembles boiling, but that involves a different physical process.

它们称为&水&的材料是XYZ，它们称为&沸腾&的过程是表面上类似于沸腾但包含的是不同物理过程。

It shows that the inertial air velocity field caused by train's movement has significant influence on fire smoke diffusion at the first few minutes.

模拟所采用的三维非均匀初场更接近于真实的物理过程，使模拟结果更有助于揭示实际火灾过程的本质。

The formation mechanism of hailstones in the storm was analyzed too. The results show that the auto-conversion of frozen drops and graupels are the main sources of the hailstones in the strong convective storm studied in the paper, but the contribution of frozen drops is greater than that of graupels. Hailstones mainly depend on the processes of collecting supercooled water to grow.

同时模拟分析了冰雹形成的微物理过程，结果表明，本个例模拟雹云中，冰雹粒子主要由冻滴和霰转化形成，但冻滴对冰雹形成的贡献要比霰大得多，冰雹含水量中心的发展演变与冻滴含水量中心的发展演变相一致，冰雹主要是通过撞冻过冷水过程而进一步长大的。
