Copernicus Sentinel-1 reveals new insight on tropical cyclones
18 October 2018
A team of experts from the French institutes IFREMER and CLS recently implemented a strategy with ESA, in order to acquire Sentinel-1 images over tropical cyclones, while developing an algorithm that enables the extraction of hurricane characteristics at a very high resolution from space. Information such as the ocean surface wind field provided at 1 km resolution could trigger perspectives for improving hurricane forecast information.
A tropical cyclone (TC) is a rotating low-pressure weather system that develops over tropical or sub-tropical waters and has organised convection (i.e. thunderstorm activity) but no fronts (a boundary separating two air masses of different temperatures and densities).
