This map shows isotachs - lines on a given surface connecting points with
equal wind speed - together with isobars - the line of equal atmospheric
pressure at 10m above the ground. The unit used is
kph (kilometers per hour). (<a href="javascript:NeuFenster()">wind-converter</a>)<br>

  <div class="eI2">The Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS<sup>&reg;</sup>) has been developed by the Marine Meteorology Division (MMD) of the Naval Research Laboratory (NRL). The atmospheric components of COAMPS<sup>&reg;</sup>, described below, are used operationally by the U.S. Navy for short-term numerical weather prediction for various regions around the world.<br>
<br>
The atmospheric portion of COAMPS<sup>&reg;</sup> represents a complete three-dimensional data assimilation system comprised of data quality control, analysis, initialization, and forecast model components. Features include a globally relocatable grid, user-defined grid resolutions and dimensions, nested grids, an option for idealized or real-time simulations, and code that allows for portability between mainframes and workstations. The nonhydrostatic atmospheric model includes predictive equations for the momentum, the non-dimensional pressure perturbation, the potential temperature, the turbulent kinetic energy, and the mixing ratios of water vapor, clouds, rain, ice, grauple, and snow, and contains advanced parameterizations for boundary layer processes, precipitation, and radiation.

  <div class="eI2">La pr&eacute;vision num&eacute;rique du temps (PNT) est une application de la m&eacute;t&eacute;orologie et de l'informatique. Elle repose sur le choix d'&eacute;quations math&eacute;matiques offrant une proche approximation du comportement de l'atmosph&egrave;re r&eacute;elle. Ces &eacute;quations sont ensuite r&eacute;solues, &agrave; l'aide d'un ordinateur, pour obtenir une simulation acc&eacute;l&eacute;r&eacute;e des &eacute;tats futurs de l'atmosph&egrave;re.
