How Does Indian Teak respond to Synoptic Rainfall Variation in multi-decadal Time Scale?
Monsoon and Post monsoon rainfall amount in SE India exhibit distinct spatial and temporal trends. The primary objective of this work is to understand how ring width index data respond to temperature and precipitation in synoptic scale. Ring width data show moderately positive response to monsoon rainfall and negative response to summer (March- May) temperature for all stations suggesting moisture deficit in warm summer. Ring width indices exhibit positive response with post monsoon rainfall at coastal location but the response gradually reduces towards inland. This study suggests that Indian teak has a potential to capture signals of the synoptic variation of post monsoon rainfall from coast to inland.
