Weather terminology?

[Manie B]

Hi guys

what i am looking for is "wikipedia or anything else" type of site that gives a description of all the little signs that appear on a weather chart in a "universal standard"

I dont quite know what to call the little inverted "f" with three legs that shows wind direction and speed AND why are they in different colours on

http://grib.us/

i cant find descriptions on Grib either - their help menu is poor and nothing on the site. The download works pretty OK

i would like to have a printout on my boat of all the meanings of all little "signs" etc.

the best i found was on the map included but it is not quite the same - it is 3 MB chart but rather nice to have in your collection of weather data

so what are the standard weather chart signs to be used?

This may help..but it is more high-tech now

the little lines indicating wind direction (no head to the arrow) but the "tailfeathers" mark wind-speed in knots 5 knots = half length and 10 knots = "full size" and 25knots = 2 full size and 1 of half size and so on... can't recall seeing more than 45knots (full gale?) as expectation of gusts at +40% I think...

The met office still uses the little circle for wind speed and not the "tailfeathers"

please see if you guys come across a tailfeathers page

anyway thanks for the input so far

http://www.bom.gov.au/jsp/marine/wind/index.jsp bugger now they use colours to define windspeed... Yup, the "wind barbs" is the way it used to be displayed... and still is here http://www.bom.gov.au/cgi-bin/nmoc/l...IDCODE=IDX0051 ...

Eh Manie,

Want to know things about the weather ? Here's a neat guideline for you.

Easy to impliment on any boat.

Weather radiofax still uses wind barbs because it is B&W and the mariner can get full world reception.

If you go there there is a users handbook pdf that explains all the forecasts, symbols, and abbrevs.

Manie, a KISS way to remember which is left and which is on the right, all the words in pairs and the ones with less letters go together "left", "red" & "port" and then the others must be on the other side "right", starboard" & "green" - so how do you determine which is "left"? well - guess, then on probabilities you will be correct, or, (right?) 100% of the time?

I like determining the weather by the testicles method - humidity can also be evaluated, amongst other things (if there is a bucksom naked lady nearby?) - like blood pressure and testosterone levels... and if you are alive?......
