We would like to thank Ryo Furue and Hiroyasu Hasumi for helpful comments and fruitful discussions. Thanks are extended to Tony Busalacchi, Eric Firing, Greg Johnson, Atsushi Kubokawa, Lynne Talley, and Mizuki Tsuchiya for pleasant discussions. Comments from two anonymous reviewers were helpful in improving the manuscript. The numerical experiments were performed on SR8000 at the Information Technology Center, University of Tokyo.
