Research Project

Modeling the Indian Summer Monsoon and its variability in the last millenium

Duration: 2021-2024

Principal Investigator: Prof. K. Ashok, University of Hyderabad

Co-Pincipal Investigator: i) Dr. Supriyo Chakraborty, IITM, Pune


  • Understanding Indian monsoon variability during the last millennium (LM), particularly the mediaval warm period (MWP) and little ice age (LIA) through PMIP3 data analysis and AGCM experiments.

  • Understanding potential connections between Indian monsoon and tropical Indo-Pacific in the LIA, MWP, in the background of external forcing changes.

  • To reconcile the proxy interpretations for LIA and MWP.

  • Improving the geographical coverage of proxy data for the LM period.

Simulating the Indian Summer Monsoon climate variability and Its teleconnections during the Holocene (2017-2021)

Using PMIP3 datasets as well as carrying out model experiments,

(1) Study the climate statistics of the Indian summer monsoon (ISM) precipitation and temperature during Holocene, with emphasis around 6k BP

(2) Better understanding of ISM variability and its teleconnections with the Indo-pacific in presence of changing solar activity during Holocene through modeling experiments, and by reconciliation with any available proxy records

(3) Importance of ITCZ for the Indo-Pacific variability during the Holocene.
