Studies on the Annual, Interannual and Climatic Variabilities of Indian Ocean Warm Pool

Abstract

The recurrent warming of oceans is an important process in maintaining the climate of earth. Ocean temperature is an important climatic indicator among others such as atmospheric humidity, tropospheric temperature, sea level, ocean heat content, temperature over land, sea ice etc. The oceans absorb large amounts of heat and Carbon dioxide, thereby reducing the impact of global warming. The important point here is the carrying capacity of the oceans and its future behavioral patterns to the present warming trend.Warm pools represent upper ocean temperatures and act as an index for climate change. Its temporal and spatial variations can have crucial impacts on climate change. This study focuses on the warming of the Indian Ocean with an emphasis on the warm pool (IOWP) with the following objectives: 1. A detailed study on the annual characteristics of IOWP 2. Understand ENSO-induced variability on IOWP 3. Deduce the long term trend SST and IOWP in response to global warming and 4. Model SST using 1-Dimensional Mixed Layer Model.
