Investigation of Spiral Rain Bands and Frontal Structures in Terms of Shallow Water Waves*

The structure of the typhoon is extremely fiat, since its altitude is very small compared with the scale of the stormy area. When we consider, hydrodynamically, the distribution of meteorological elements within typhoons and travelling cyclones, we may find in them close relation with shallow water phenomena that can be seen in a small depth of water. We made theoretical analysis and experimental observation of that fact during the recent four-year period, and got fruitful results in this spring.
