Evidence of warm core structure maintenance over land: a case study analysis of cyclone Kelvin

Abstract Cyclone Kelvin made landfall in northwest Australia as a category 1 storm on 18 February 2018. After landfall, tropical cyclones typically weaken due to the exhaustion of moisture supply. continued intensify with winds gusting 100 knots and significant flooding well inland. A distinct eye feature also formed after landfall. An analysis meteorological satellite, MERRA2 reanalysis, Global Data Assimilation System (GDAS) data was employed case study Kelvin. Using cyclone phase diagram, it is confirmed that warm core structure maintained move inland, even through period brief inland intensification.
