Share New Delhi: Indian Scientists have found a promising technique for early detection of development or strengthening of tropical cyclones in the atmospheric column prior to satellite detection over ocean surface in North Indian Ocean region. Early detection of Tropical cyclones has wide socio-economic implications. 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. Prior to the formation of cyclonic system over the warm oceanic environment, the initial atmospheric instability mechanism, as well as the vortex development, is triggered at higher atmospheric levels. These cyclonic eddies are prominent features in the vertical atmospheric column encompassing the disturbance environment with a potential to induce and develo ....
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.
