Morning Pops, Morning Fellas and good morning to all who come to wish Weldon a Happy Friday. I hope everybody has a great day!
Hey Jobs, here is an overview of the three currents, NEC (North Equatorial Current), NHRC (North Hawaiian Ridge Current and the HLCC (Hawaiian Lee Counter Current) are pretty much related. Here is a general overview of location and how they interact. There is a lot more info on this, NOAA has a bunch of stuff you can check out but here is a general on each.
South of Hawai'i, the surface North Equatorial Current (NEC) reaches an average westward speed of 17 cm/s (0.35 knot) at 13 N, and gradually decreases towards the islands. Between 18 N and 22 N, the currents are strongly influenced by the islands. The NEC forks at Hawai'i island; the northern branch becomes the North Hawaiian Ridge Current (NHRC), and intensifies near the islands with a typical width of 100 km (54 NM) and speed of 25 cm/s (0.5 knot). West of the islands, two elongated circulations appear. A clockwise circulation is centered at 19 N, merging to the south with the southern branch of the NEC. A counter-clockwise circulation is centered at 20 30'N. Between them is the narrow Hawaiian Lee Counter Current (HLCC), extending in longitude from 170 W to 158 W. Surface currents over the western islands and north east of the NHRC are variable and their average is smaller than can be estimated from existing data.
