Meteorological reports indicate Cyclone Arnab absorbed moisture from a system over Tamil Nadu but did not merge with it.
Cyclone Arnab, a low‑pressure system developing in the Bay of Bengal, was closely monitored by the India Meteorological Department (IMD) as it moved westward towards the Indian coast.
Analysis of satellite imagery and atmospheric data revealed that Arnab drew moisture from a separate low‑pressure system situated over Tamil Nadu. The interaction intensified the cyclone’s convection, but the two systems did not coalesce.
According to IMD officials, the lack of merger meant that Arnab retained its distinct structure, allowing forecasters to predict its track and intensity more accurately.
The event underscores the complexity of cyclone development in the Bay of Bengal, where multiple systems can interact without fully merging, affecting rainfall patterns along the eastern coastline.
