A polarizing prism consisting of two calcite prisms cemented such that they deviate the two emerging beams (which are perpendicularly polarized) by nearly equal amounts in opposite directions.
Industry:Weather
A plot of the locations of a depression, or area of low pressure.
Industry:Weather
A plot of the energy distribution of turbulent eddies versus wavelength or frequency.
Industry:Weather
A photometer that measures the amount of light received from a distant light source. When specifically used to measure the transmissivity of the intervening atmosphere (or other medium), it is usually termed a transmissometer. See visibility meter.
Industry:Weather
A phenomenon investigated experimentally and theoretically by G. I. Taylor in which the relative motion of a homogeneous rotating liquid tends to be the same in all planes perpendicular to the axis of rotation. For example, if a sphere is introduced as an obstruction, the fluid flows around it as if it were a cylinder extending the entire depth of the fluid parallel to the axis of the system. It is due essentially to the presence of very geostrophic, homogeneous conditions so that the thermal wind is zero. It occurs at very low values of the Rossby number.
Industry:Weather
A period of a number of consecutive days on each of which precipitation exceeding a specific minimum amount has occurred.
Industry:Weather
A pattern of waterfilled sinks, cave-ins, and other small depressions caused by the local melting of permafrost.
Industry:Weather
A numerical model with horizontal resolution arranged to be nonuniform. This enables finer details of the solution in a chosen region of interest to be captured in a way that preserves computational economy elsewhere. See reduced grid, nested grids.
