interpretation
1

basis: PDSI gives soil moisture status which in turn is related to precipitation and temperature

direction: negative

basis: In the monsoon season, high temperature usually indicates less rainfall and low relative humidity, which can make the tree ring cellulose d18O heavier. Low PDSI indicates a dry condition.
