Referring to sound waves with frequencies higher than those at the upper limit of unimpaired human hearing, usually between 16 and 20 KHz.
Industry:Weather
Ratio of the distance covered by the air to the time taken to cover it. The instantaneous speed corresponds to the case of an infinitely small time interval. The mean speed corresponds to the case of a finite time interval. It is one component of wind velocity, the other being wind direction).
Industry:Weather
Random noise that has uniform power spectral density at every frequency in the range of interest.
Industry:Weather
Rain formed from a cloud having temperatures at all levels above 0°C (32°F), and resulting from the droplet coalescence process.
Industry:Weather
Quantity of water required by a specified area, to satisfy all types of water demands, for a given period of time.
Industry:Weather
Proportional to the number of equally likely states that a system may attain. Boltzmann proposed that the entropy ''S'' and the thermodynamic probability ''W'' were proportional, and Planck subsequently showed that ''S'' = ''k'' ln ''W'' with ''k'' Boltzmann's constant. This result is of such fundamental significance in physics that it was carved as an adornment on Boltzmann's gravestone in Vienna. See third law of thermodynamics.
Industry:Weather
Physical methods of moving substances or characteristics. Methods of transport in the atmosphere include turbulent transport by eddy winds and advective transport by the mean wind.
Industry:Weather
Pressure ice in which two floes have been pushed into the air, leaving an air space underneath.
