Historically, the Beaufort wind force scale (created by Beaufort) provides an empirical description of wind speed based on observed sea ally it was a level scale, but during the s, the scale was expanded to 17 levels. There are general terms that differentiate winds of different average speeds such as a breeze, a gale, a storm, or a hurricane.

During this three day period a strong atmospheric front passed over the location of an ARG. When it was not raining, the acoustic estimate of wind speed matched a nearby mechanical anemometer to within ± 1 m/s (very good agreement).

Because rain is so loud underwater, acoustical wind speed measurements are only possible when is not raining. The Spanish Deepwater Buoys Network, in Januarymeasured a wave height of metres ( ft).

The data was taken at the buoy Vilán-Sisargas in Galicia (Spain) during the winter storms, which were particularly severe in Atlantic waters. MS Marco Polo was struck by a rogue wave on the English Channel (February ).

An year-old man. Winter‐time (–86) observations of sea‐level, surface waves, currents, bottom pressure, and water properties were made on the Scotian Shelf as part of the Canadian Atlantic Storms Program.

Satellite observations reveal a storm surge of 1 m in the early morning of Septem (UTC) after the passage of the storm, consistent with the tide-gauge measurements.

WOCE set target accuracy goals: 20% for wind stress and – m s −1 for wind in up to 10 m s −1, with accuracy in wind speed to obtain sensible and latent heat fluxes to 10–15 W m −2. Surface heat fluxes accurate to within 10% of the monthly mean were : Russ E. Davis, Lynne D.

).The field is elongated in a general N–S direction, approximately km long and km wide, covering an area of approximately km 2 at water depths ranging from 20 to 80 m (Fig. In fluid dynamics, wind waves, or wind-generated waves, are water surface waves that occur on the free surface of bodies of result from the wind blowing over an area of fluid surface.

Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of standard atmosphere (symbol: atm) is a unit of pressure defined asPa (1, hPa; 1, mbar), which is equivalent to mm Hg, inches Hg, or psi.

The atm unit is roughly equivalent to the mean sea-level. Because the M 2 tidal constituent dominates in most locations, the stage or phase of a tide, denoted by the time in hours after high water, is a useful concept. Tidal stage is also measured in degrees, with ° per tidal cycle.

Lines of constant tidal phase are called cotidal lines, which are analogous to contour lines of constant altitude on topographical maps, and when plotted form. Calm conditions, wind speeds 0 to 2 miles per hour are present 11 percent of the time.

The average wind speed is knots. Wind speeds exceeding 15 knots are mainly from the west, southwest, and south directions during June through September (Figure 11).

Wind speeds exceeding 15 knots are predominantly from the east and northeast. Publisher Summary. This chapter explores the Amazon River dolphin commonly known as boto.
