2. Line echo wave pattern - Wikipedia

   en.wikipedia.org/wiki/Line_echo_wave_pattern

   Radar schematic of a LEWP. This shape is a single wave along the pattern, for real LEWPs this shape is tessellated repeatedly in a linear fashion. A line echo wave pattern (LEWP) is a weather radar formation in which a single line of thunderstorms presenting multiple bow echoes forms south (or equatorward) of a mesoscale low-pressure area with a rotating "head".

3. Doppler radar - Wikipedia

   en.wikipedia.org/wiki/Doppler_radar

   AN/APN-81 Doppler radar navigation system, mid-1950s. Doppler radar tends to be lightweight because it eliminates heavy pulse hardware. The associated filtering removes stationary reflections while integrating signals over a longer time span, which improves range performance while reducing power. The military applied these advantages during the ...

Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).

6. Col (meteorology) - Wikipedia

   en.wikipedia.org/wiki/Col_(meteorology)

   A col, also called saddle point or neutral point, is in meteorology, the point of intersection of a trough and a ridge in the pressure pattern of a weather map. It takes the form of a saddle where the air pressure is relatively higher than that of the low-pressure regions, but lower than that of the anticyclonic zones. [1]

7. Weather map - Wikipedia

   en.wikipedia.org/wiki/Weather_map

   A popular type of surface weather map is the surface weather analysis, which plots isobars to depict areas of high pressure and low pressure. Cloud codes are translated into symbols and plotted on these maps along with other meteorological data that are included in synoptic reports sent by professionally trained observers.
