Ocean–Atmosphere Interactions during Hurricanes Marco and Laura (2020)

During August of the 2020 Atlantic Hurricane Season, Gulf Mexico (GoM) was affected by two subsequent storms, Hurricanes Marco and Laura. entered GoM first (22 August) briefly promoted to a Category 1 storm. Laura followed closely (25 attained 4 status after period rapid intensification. Typically, hurricanes do not form this close together; study aims explain existence both through analysis air-sea fluxes, local thermodynamics, upper-level circulation. The its quality warm, high ocean heat content waters proved be resilient powerful reservoir moisture fuel for hurricanes; however, an area lower due circulation dynamics crucial in evolution An wind shear further explained hurricanes. Furthermore, suite satellite observations model outputs were used evaluate biophysical modulations GoM. cold core eddy (CCE) Mississippi River surface plume had greatest oceanic responses; initialized extended temporally spatially Reduced sea temperatures (SST), changes salinity (SSS), Chlorophyll-a (Chl-a) concentrations are related translation speeds, respective contributions hurricane winds precipitation evaluated work.
