The term originally derives from the early fourteenth century sense of trade (in late Middle English) still often meaning "path" or "track". [2] The Portuguese recognized the importance of the trade winds (then the volta do mar, meaning in Portuguese "turn of the sea" but also "return from the sea") in navigation in both the north and south Atlantic Ocean as early as the 15th century.

All of Vietnam was under the French colonial regime from 1885 until the Japanese coup d'état of March 1945. In 1887, the French created the Indochinese Union including the three separately-ruled territories of Tonkin, Annam, and Cochinchina, which were parts of Vietnam, and the newly acquired Cambodia; Laos was created at a later time.

The primary reasons for its existence were to prevent infiltration of troops through the DMZ into I Corps and to direct counterbattery fire against People's Army of Vietnam (PAVN) artillery. Navy ships would unload supplies at the Cửa Việt Base and these would be taken up the Cua Viet River to Đông Hà Combat Base. Typically ships would ...
The strength of the sea breeze is directly proportional to the temperature difference between the land and the sea. If a strong offshore wind is present (that is, a wind greater than 8 knots (15 km/h)) and opposing the direction of a possible sea breeze, the sea breeze is not likely to develop. [3]
Knowing the wind sampling average is important, as the value of a one-minute sustained wind is typically 14% greater than a ten-minute sustained wind. [16] A short burst of high speed wind is termed a wind gust ; one technical definition of a wind gust is: the maxima that exceed the lowest wind speed measured during a ten-minute time interval ...

In fluid dynamics, a wind wave, or wind-generated water wave, is a surface wave that occurs on the free surface of bodies of water as a result of the wind blowing over the water's surface.
Sir Francis Beaufort. The scale that carries Beaufort's name had a long and complex evolution from the previous work of others (including Daniel Defoe the century before). In the 18th century, naval officers made regular weather observations, but there was no standard scale and so they could be very subjective — one man's "stiff breeze" might be another's "soft breeze"—: Beaufort succeeded ...
