The component of the velocity directed along the velocity vector (streamline), with magnitude equal to the speed of the parcel at that point.
Industry:Weather
The component of the vorticity vector along the local vertical. References to vorticity usually imply the vertical component of that vorticity as a scalar quantity.
Industry:Weather
The component of the wind vector that is normal to the radial viewing direction of a Doppler radar or Doppler lidar and therefore is not measurable. Various assumptions and techniques are employed to estimate this missing component. See Also Doppler velocity.
Industry:Weather
The components of the stress tensor remaining after the pressure, that is, the mean of the three normal stresses, has been subtracted out from each of the normal stresses. See Reynolds stresses.
Industry:Weather
The components of the stress tensor that are tangential to the faces of the fluid element.
Industry:Weather
The condition in the accretion of supercooled water droplets onto ice in which the temperature of the ice remains at the melting point because of the release of the heat of fusion by the freezing droplets. The ice formed usually contains some liquid water (spongy ice) and its surface during growth is mostly wet. The ice produced by wet growth is often quite clear and is called glaze. Compare dry growth.
Industry:Weather
The condition produced by a change in wind velocity (speed and/or direction) with height.
Industry:Weather
The continuation of the Norwegian Current. It carries 3–5 Sv (3–5 × 10<sup>6</sup> m<sup>3</sup> s<sup>−1</sup>) of water from the Atlantic into the Arctic Ocean. Another 1 Sv enters the Arctic Ocean through the Barents Sea.
Industry:Weather
The convective cell of a cumulonimbus cloud having lightning and thunder.
Industry:Weather
The conversion of seawater from one water type to another, by air– sea fluxes or mixing.
