Q2. What are the future works mentioned in the paper "Superimposition of wind seas on pre-existing swells off goa coast" ?
A more scientifically relevant problem is the use of the local conditions to study the influence of swell on the local wind generation.
Q3. What is the effect of sea breeze on the oceanography of Goa?
During the summer season (October – April) they observed that the sea breeze is most prevalent between 12 and 21 h (local time), and typically produces 1 – 1.5 m high waves with periods ranging between 6 and 9 s. Masselink and Pattiaratchi (1998) pointed out that following the onset of sea breeze, addition of locally generated wind waves to background swell resulted in an increase in wave height and a decrease in mean wave period.
Q4. What is the purpose of the present study?
The present study aims at (i) understanding the diurnal variation of wave parameters along and off the coast of the Goa region and (ii) studying the impact of sea breeze on the local wave climate.
Q5. What is the current plan for the Goa coast?
Shipping Corporation of India has initiated a program for the Goa coast, where the Mormugao Port Trust is situated, to fix an Inland Vessel Limit (IVL) for the movement of vessels such as barges and boats based on a maximum wave height of 2 m.
Q6. What is the effect of sea breeze on the environment?
Sea breeze can create a highly dynamic environment in the nearshore regions, and beaches may respond rapidly to the changing wind wave climate.
Q7. What are the correlation coefficients for the wind sea?
The model wave parameters give correlation coefficients of 0.77, 0.72 and 0.63 for total, swell and wind sea heights, respectively with the measurements.
Q8. Why were the AWS winds not used for wave simulations?
the AWS winds were measured on the land (of course, close to the coast) and the magnitudes (especially uvelocity) are significantly low compared to the NCEP winds of the grid closest to the coast (Figure 5), the AWS winds were not used for wave simulations.
Q9. What are the implications of the cross sea conditions?
Although relatively mild, the cross sea conditions will have a considerable impact on the local maritime activities and harbour management.
Q10. What is the wind direction of the Goa coast?
The sea breeze and land breeze systems are nearly perpendicular to each other, the former roughly parallel and the latter perpendicular to the orientation of the Goa coast.
Q11. What are the wind parameters used by Vethamony et al.?
These winds have been used by Vethamony et al. (2006) to simulate waves in the north Indian Ocean, and the modelled wave parameters match reasonably well with measurements.
Q12. What are the wind patterns for the coastal region off Goa?
(Figure 5)Winds from the AWS for the coastal region off Goa show nearly semi-diurnal variations both in their magnitude and direction (Figure 2).
