WX Question. "jp"?

Wed Dec 03, 2003 7:56 am

Looking at these Caribbean METAR reports, can anyone tell me what the "JP" means exactly in the remarks section ?

Never heard of "JP"... Only thing that even comes close is UP= UNKNOWN PRECIPITATION. If you got your original stuff in paper form, any chance you've got a malformed "U" masquerading as a "J"?

>> any chance you've got a malformed "U" masquerading as a "J"? <<

I cut and pasted them right off the ADDS website. The "J" is consistent from 3 different stations, so I would suspect that it is not an error. Given the reports it must mean rain showers or virga using some sort of non standard terminolgy ? Perhaps Spanish instead of the standard French ? I've never seen it used anywhere else.

It's entirely possible that it is a non-US standardized abbreviation (in fact, it has to be)...I'll find out what it means shortly, hopefully  Smile/happy/getting dizzy

Actually, the name "METAR" comes from a French acronym for the forecast (translating into aviation routine weather report)...bonus points for anyone who nails it!

The apostrophes are supposed to be the accent mark over the preceeding letter. Tell me how to do the accents it if anyone knows.

Honestly folks, JP stands for adjacent showers. It is a regional exception you find with METARS now and then. Now how they get JP from adjacent showers, I have no idea, but that is what its intended meaning is.

Thanks for the update. I had asked our resident METAR/TAF guru and he didn't know either, so we've both learned something...

I had to go about the long way to find that out last year while doing some charter debriefs. I called Barbados met office to find out since no one knew its meaning here in the states.

I think "pluie" is "rain" in French...

I'm actually going to guess "jointe pluie"....joined rain....

Nice one!  Smile This has turned out quite informative - i've always looked at the weather and wondered how these people come up with such helpful  Confused abbreviations for various phenomena. Now i know!
