Question

Why is rain illustrated as the color green on a radar?

Answer 1

Modern weather radars are mostly doppler radars, capable of detecting the motion of rain droplets in addition to intensity of the precipitation. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather. Precipitation type is indicated by the color - green is rain, pink is a mix of rain, freezing rain, sleet, and/or snow, and blue is snow.

Answer 2

dat was the chosen color and the color changes as the precipitation gets heavier

Answer 3

I'm not sure why that particular color was chosen, but as you probably know, green is not the only color. Green indicates generally light rain. Next is yellow, with moderate rain. Then orange, red, and purple, which oftentimes indicates hail. Some radars also have black and white as the heaviest colors, which you rarely see.

Answer 4

That's because it was the color that was chosen to be assigned to represent rain on a radar image. Different colors have been chosen to represent different intensities and precipitation.

Answer 5

It is an arbitrary color scheme.  Radar is based on the intensity of the object that the radar beam hits, rain, snow, hail, insects, etc.  Green is usually picked to denote light rain going up to yellows, reds, etc. for heavier precipitation and thunderstorms.

You could buy your own radar if you had enough radar and make rain pink if you wanted to.  Some go 'go get 'um' networks use this to their advantage and make light precipitation look heavier by tweaking the scheme.  It's all about the ratings.
