  • The spore pollen records and time sequence of the paleoclimate parameters at Foyechi Pond of Taibai Mountain reveal the character of Little Ice Age and Medieval Warm Period.Little Ice Age spans from 1420 AD to 1920 AD.The annual mean temperature in January and July during this period has shown considerable inconsistency of the changes of winter monsoon and summer monsoon in this area.At the beginning of Little Ice Age,there was a strengthening of the winter monsoon and consequent southwards expansion,with the summer monsoon weakened and fluctuated,and the annual total precipitation increased.At the end of Little Ice Age,there was a gradual decline of winter monsoon and a sudden strengthening of summer monsoon,with decreased annual total precipitation.The precursor of end of Little Ice Age was gradually weakening winter monsoon,abruptly enhanced summer monsoon,and relatively rare precipitation.The Medieval Warm Period (1200-1340 AD) was witnessed violent disastrous climate with warm summer and cold winter.
