South China Sea Project Document for Chinas Hepu Seagrass Habitat Demonstration Site
The seagrass bed, including the adjacent area, is complicated, consisting of a deep slot and sand ridge arrangement. There is a strong current along this part of the coast, which causes erosion due to the tides and wave action. The topography of the seabed includes tidal shoal, tidal and deep slot, tidal sand ridge, and seabed plain.The weather is influenced by the south subtropical ocean quarter breeze Influence of the atmospheric-circulation and the geographic location results in some favourable weather characteristics, for example, winter has no frost, summer is not hot, spring and autumn are short, and the quarter breeze is extensive. Average air temperature is 22.9 , with a high of 38.2 , and a low of 1.5 . Wind direction varies with the season throughout the year with prevailing winds in the winter from the northeast and from the southwest in summer, with an average wind velocity of 3.7m/ s. The average annual rainfall was 1573.4 mm in recent years, with 83% occurring in the summer half of the year. The rain falls on average for 144 days per year. Influence of typhoons is important, with two or three occurring every year, usually between July and September, (CCCBR, 1993).
