“Shamal” swells in the Arabian Sea and their influence
along the west coast of India - V. M. Aboobacker, P. Vethamony and R. Rashmi (Geophysical Research Letters)

Wave data collected off Ratnagiri, Goa and Dwarka
along the west coast of India during winter season (NE
monsoon and early pre‐monsoon) present distinct wave
characteristics with periodicity ranging between 2 and 5
days associated with shamal events. The notable wave
characteristics during these events are: an increase in wave
height, decrease in swell period and a common propagation
direction (northwest) for wind sea and swell. IFREMER/
CERSAT blended winds clearly show the presence of
strong northwesterly winds in the Arabian Peninsula and
northwestern Arabian Sea, which are associated with the
winter shamal events. The winds during such events
generate large northwesterly swells (shamal swells) in the
northwestern Arabian Sea and propagate towards the west
coast of India in the NW direction with mean periods
ranging between 6 and 8 s. Numerical simulations
reproduce the shamal swells over the Arabian Sea, and they
can be traced all along the west coast of India, however,
with lesser order of magnitude from north to south.
Generation and propagation of shamal swells and their
influence along the west coast of India have been
described.
