International CAWSES-II Symposium

Edited by: Mamoru Yamamoto, Kazuo Shiokawa, Takuji Nakamura, Nat Gopalswamy

This special issue presents papers from the International CAWSES-II Symposium (November 18-22, 2013 at Nagoya University, Japan). CAWSES-II (Climate And Weather of the Sun-Earth System II) is an international scientific program sponsored by SCOSTEP (Scientific Committee on Solar-Terrestrial Physics) that continued from 2009 to 2013. The program was established with the aim of significantly enhancing our understanding of the space environment and its impacts on life and society. This special issue covers the six major themes addressed by CAWSES-II.

    Regional climate pattern during two millennia estimated from annual tree rings of Yaku cedar trees: a hint for solar variability?

    We analyzed trees that have survived on Yaku island (Yakushima) for 2,000 years. Quite surprisingly, the Fourier and wavelet analyses of the annual growth rate identified 2 cycles of periodicities of 11 and (2...
