概要

論文の詳細を見る
Cool weather damage, frost injuries, floods, droughts and strong wind damage were investigated as typical meteorological disasters occurred during the 36 years after 1950 in the Sanjiang Plain. Records of the disasters were assembled from numerous scientific reports and books published in China and listed in a regular time series. The Sanjiang Plain suffered cool weather damages twelve times and floods and droughts seven times during the period. The areas which were damaged by strong winds have increased rapidly in the last 20 years. A power spectral analysis indicates that there is some periodicity in the year to year fluctuations of thermal conditions and precipitation.
