摘要
Short-term (shorter than a century) temperature and rainfall variations correlate roughly along the Afrasian arid belt over the last 500 years. Among various external forcings, solar activity might be one of the most important. The spectral analysis of climatic change in China and auroral number series of the last 1700 years shows some potential relations at the time-scales of decades to century.
