A team of scientists has devised a novel method for early detection of tropical cyclones.
The method aims to identify initial traces of pre-cyclonic eddy vortices in the atmospheric column, prior to satellite detection over ocean surface, and track its spatio-temporal evolution, the Department of Science and Technology (DST) said.
So far, remote sensing techniques have detected them the earliest. However, this detection was possible only after system developed as a well-marked low-pressure system over the warm ocean surface.
A larger time gap between the detection and the impact of the cyclone could help preparation activities.
Early detection of tropical cyclones has wide socio-economic implications, the DST said.
