The six-hourly best tracks (black line overlaid on green color) and intensity (open colored circles corresponding to the dates and intensity) of TC Ockhi are marked. The classification of tropical systems by IMD with respect to wind speed is classified as Depression (D) (17–27 knot; kt), Deep Depression (DD) (28–33 kt), Cyclonic Storm (CS) (34–47 kt), Severe Cyclonic Storm (SCS) (48–63 kt), and Very Severe Cyclonic Storm (VSCS) (64–89 kt) and are marked as cyan, blue, green, orange, and purple circles respectively along the track of TCs. The number adjacent to each circle indicates dates of cyclone reached at that location. Red colored triangles inside a white rectangular box indicate the A-Float (WMO ID 2902202) profiling locations before and after TC Ockhi (29 November 2017 to 29 December 2017). The dark green triangle indicates A-Float profiling locations in close proximity during TC Ockhi: 29 November to 06 December 2017. The star symbol represents the location of A-float measurements and the water sample collected from the ship (~ 2 km distance) on 05–06 February 2018 for validation and correction.
