INTERANNUAL, DECADAL AND CENTURY SCALE CLIMATIC CHANGES REVEALED BY STALAGMITE RECORDS

The stalagmite chronological table is established based on the definit ion of annual character of microlayers of a stalagmite by comparing th e laminated rhythm to natural cyclic processes. Climatic anomalies las ting over ten years and rapid climatic changes such as abrupt changes of mean value, of variability, of trend and of cycles are discovered f rom the stalagmite chronological table.
