The propagation characteristics of ultrasound in sea water and its ultrasonic reflection loss on the sea bottom or on fish schools must be studied for both the design and the practical operation of echo sounders, fish finders... The propagation attenuation in a direction vertical to the sea surface is the result mainly of spherical divergence, but the attenuation in a horizontal direction is caused partly by absorption as well. This absorption becomes larger at higher frequencies...  2, record 1, English, - propagation%20attenuation

The depletion of air in a layer or region of the atmosphere due to outflowing winds.  2, record 3, English, - divergence

Record number: 3, Textual support number: 1 CONT

Simply stated, convergence is defined as the increase of mass within a given layer of the atmosphere, while divergence is the decrease of mass within a given layer of the atmosphere.... Divergence. Winds in this situation produce a net flow of air outward from the layer. We associate this type of divergence with high-pressure cells, where the flow of air is directed outward from the center, causing a downward motion. Divergence, too, is classified as either horizontal or vertical.  3, record 3, English, - divergence

An operational forecaster locates regions of upper level divergence by locating the divergence sector of a vorticity gradient near the LND (Level of Non-divergence). The LND is closest to the mandatory level of 500 mb, thus upper level vorticity is usually plotted on this prog. The LND is the general level that separates the low levels of the troposphere from the upper levels. Vorticity advection is best assessed near the LND.  2, record 8, English, - level%20of%20non%2Ddivergence
