Meandering Stream II

Spiral Meandering

The complex, so called meandering, dynamics of spiral waves in excitable media is examined from the point of view of bifurcation theory. A computational bifurcation analysis is made of spiral dynamics. It is shown that spiral meandering is organized in parameter space around a codimension-two point where a Hopf bifurcation from rotating waves interacts with symmetries on the plane. A simple mod...

The Study of Meandering Phenomenon on the Basis of Stream Power

On the basis of stream power, the phenomena including regime channel establishment and river meandering can be studied. So, previous researchers have suggested and developed the stream power theory and believed that stream power minimization affects these phenomena. In this paper, the stream power theory and a criterion for meandering river modeling will be studied. Then the conclusion of case ...

Saturn’s Northern Hemisphere Ribbon: Simulations and Comparison with the Meandering Gulf Stream

Voyager observations of Saturn in 1980–81 discovered a wavy feature engirdling the planet at 478N planetographic latitude. Its latitude coincides with that of an eastward jet stream, which is the second fastest on Saturn after the equatorial jet. The 478N jet’s wavy morphology is unique among the known atmospheric jets on the gas giant planets. Since theVoyagers, it has been seen in every high-...

Interdisciplinary Meandering in Science

I was a graduate student in mathematics at Princeton immediately following World War II, 1945–1947. In those days, with veterans of the war inundating universities, there was no option but to earn a Ph.D. within two years. My thesis research was in functional analysis, an area of abstract mathematics. My mentor was Professor S. Bochner, a distinguished contributor to harmonic analysis. My class...
