Model Derived Depth of 26°C Isotherm

Catalog Info

Depth of 26°C isotherm (D26) in the ocean and its derivative Tropical Cyclone Heat Potential (TCHP) are useful indicators of genesis, intensification and propagation of tropical cyclones. Hence, monitoring of these two parameters and the ability for their advance prediction is quite significant. A modified one-dimensional (1-D) ocean mixed layer model is deployed to predict D26 and TCHP 12 hours and 48 hours in advance on a daily basis following the methodology presented in Swain and Krishnan (2013, NRSC-ECSA-OSG-May2013-TR-529). The model is forced with forecast surface meteorological parameters obtained from an Atmospheric General Circulation Model of National Centre for Medium Range Weather Forecast (NCMRWF), New Delhi.
