Rip Currents

Context

Indian National Centre for Ocean Information Services (INCOIS) and Indian Space Research Organisation (ISRO) will monitor and issue operational forecast alerts of rip currents. 

What are Rip currents?

∙ Rip currents are strong, narrow, seaward flows of water that extend from close to the shoreline to outside of the surf zone. 

∙ They are found on almost any beach with breaking waves and act as “rivers of the sea,” moving sand, marine organisms, and other material offshore.

∙ They are a common and potentially dangerous coastal phenomenon. 

Cause of Rip currents

∙ These currents often form when waves break near the shoreline. 

∙ Submerged structures such as sandbars, jetties, or reefs alter the flow of water, creating channels where currents can develop.

∙ As waves approach the shore, they may converge and create imbalances in water distribution, leading to the formation of channels through which excess water flows back to the ocean.

Indian National Centre for Ocean Information Services (INCOIS)– INCOIS is an autonomous body under the Ministry of Earth Sciences (MoES) and is a unit of the Earth System Science Organisation (ESSO).– ESSO-INCOIS was established in 1999 under the Ministry of Earth Sciences (MoES) and is located in Hyderabad.– Indian Tsunami Early Warning Centre (ITEWC) is also housed in the INCOIS.– Mandate: To provide the ocean information and advisory services to society, industry, government agencies and scientific community through sustained ocean observations and systematic and focussed research.
