Help With TAF interpretation
Hello,
I need some help with TAF interpretation.
1.
I got this wierd TAF :
TAF LLSD 201350Z 2015/2103 33008KT CAVOK BECMG 2019/2021 14003KT= TAF LLHA 201350Z 2015/2103 33008KT CAVOK BECMG 2019/2021 14003KT
what is the deal with =TAF LLHA (its a different airport)?
2.
When a TAF says BECMG can i asume it will change aproximetly in a linear fashion (i mean wind mainly)?
3.
When some info is missing at a BECMG can i assume it remains unchanged from the previous COMPLETE (or BECMG) line.
Thanks in advance

1. Looks like another TAF has just been tagged on the end there, guess it's an admin error.
2. I believe it does change in a roughly linear fashion.
3. Yes, you can!

2. BECMG = indicates an expected permanent change in the forecast met conditions, at either a regular or irregular rate occurring at an unspecified time within the period.
A basic definition with which you should probably familiarise yourself

In message/signals traffic the '=' means 'break', i.e. 'this is the end of one part of the message now for a new part of the message'.
So in the example above there are 2 TAFs in the same message text separated by a 'break'.

hi
Hello again,
I'm very new to the TAF interpreting (i'm from paragliding sport) and i want your interpretation on this TAF:
COMPLETE 2315/2403 26015KT 9999 SCT030
TEMPO 2315/2318 BKN025
BECMG 2320/2322 20008KT
TEMPO 2322/2403 BKN022
what the COMPLETE actually means? if the TEMPO overrides it immediately?
Also, does it mean that after the TEMPO it will return to the Complete forecast (with the clouds and wind and all?)
Thanks guys

FWIW it doesn't look like a proper TAF. Normally at that place you'd expect the word "TAF", the ICAO code of the airfield and the time of issue. Like this:
TAF EHWO 241055Z 2412/2421 31009KT 9999 FEW045 SCT350
BECMG 2418/2421 VRB03KT SCT300=
Where did you get that TAF from, and are you sure that there's not some sort of interpretation/filtering going on?

A quick google search throws up this, which may be a good starting point:
http://www.ukweather.freeserve.co.uk/metarpg.htm
Or
Decoding a TAF
I've not seen COMPLETE before, but TEMPO (and INTER) have specific meanings - for TEMPO, the conditions may persist for up to an hour, INTER up to 30 mins. They do not change the base forecast, they're used for temporary phenomena.
I would read your taf as "COMPLETE... BECOMING" and the tempo's as temporary changes - it's rather odd that the TAF ends at the same time as the second tempo kicks in.

I know tha basic TAF interpretations,
what I want to produce is a hour by hour forecast from the TAF.
so what i'm trying ti understand is how should i understand the BECMG?
Should i understand that the conditions are changing within the BECMG time or in that time they are already those (that reported in the BECMG), does they stay the same as in the BECMG after the BECMG period is over? (as i understand in TEMPO they dont).
(btw the complete thingy is mine formating stuff)

Each year as we wander round AeroExpo we have a go at the Met people on their stand there, and ask why TAFs and METARs can't be in English instead of obscure code. We don't live in the age of semaphore any more, so we shouldn't need to have to decode gibberish.
The answer was always - "well, its international" , and ours was "NOAA does it, why can't you?". That was the end of the conversation, but someone once promised in an email that they'd do it on the next update. I don't think they have and I didn't see them this year to have another whinge.

hi again
Hi again,
more question
first: is the time here -> 2818/2918 is in GMT also?
second: more of a note the forecast time is 19:50Z in the TAF (TAF LLBG 281950Z) and its 22:50 local time but its only 9 oclock here(Israel) how can i let them know they have some kind of bias?
Thanks guys.

I want to be sure on something once again...
1) 2915/3003 32012KT CAVOK
2) BECMG 2917/2919 27012G22KT 9999 SCT010
3) TEMPO 2919/3003 BKN010
4) BECMG 2920/2922 22010KT
in the following example in the (4) line the BECMG has no cloud definition,
so, do i assume no clouds OR take the clouds from the (2) BECMG?
thanks guys
