This document provide guidelines for color codes to indicate severity of hazards in public warnings. There are many different systems are already in use, such as colour state of meteorological condition or former Homeland Security Advisory System , and the standard is intended to be an approach to eliminate confusion due to such differences.
Colour states is a system used for quickly showing meteorological conditions. [1] [2]Meteorological colour states are determined by the relevant worst condition from the visibility and significant cloud height.
WSR-74C radars were generally local-use radars that didn't operate unless severe weather was expected, while WSR-74S radars were generally used to replace WSR-57 radars in the national weather surveillance network. When a network radar went down, a nearby local radar might have to supply updates like a network radar. [4]
The scale of dBZ values can be seen along the bottom of the image. dBZ is a logarithmic dimensionless technical unit used in radar.It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).
