Abstract: | The time series of accumulation in recent 300 years correlated well with solar activity in Dasuopu ice core. Results of spectrum
analysis on the accumulation time series of the Dasuopu ice core shows that there are some periods that coincide with the
periods of solar activity. By comparing the long-time change trend of the accumulation in the Dasuopu ice core with various
kinds of indexes of solar activity intensity, a negative correlation is found between the trend and solar activity. |
