Why WX is the abbreviation for Weather.

If you are reading this blog, follow me on social media or follow weather at all you likely know what WX means and stands for. Social media has kinda made WX go mainstream after being mainly confined to weather geeks, ham radio operators, news people and military members. You have likely seen my name wxbrad or hashtags like #cltwx #ncwx and #scwx, if you spend anytime on-line.


If you don’t already know WX is morse code shorthand for the word weather. So it is commonly used as the abbreviation for the word weather.

Brief history lesson  here: In 1836, Samuel Morse(pictured left) demonstrated the ability of a telegraph system to transmit information over wires. The information was sent as a series of electrical signals. Short signals are referred to as dits (represented as dots). Long signals are referred to as dahs (represented as dashes). With the advent of radio communications, an international version of Morse code became widely used. Back when the only form of communication was the telegraph and radio. People used morse code and they used lots of shorthand or abbreviations.

Kinda like today’s texting when people use BRB, LOL or the countless other texting and chat shorthand. To save time and characters, telegraph operators would use shorter versions of full words. Imagine trying to wait for whole sentences when each morse code character looks like this in morse code.




So in many ways our modern social media, chat and texting has kinda created a whole new version of shorthand similar to when morse code and the telegraph became the first long-range form of communication. Today morse code and it’s shorthand are still used in the military and among many amateur radio operators.
Even though, not many people use morse code the abbreviation stuck. So WX means weather and my Twitter name and blog are wxbrad which really is shorthand for Weather Brad.
