Tässä on tullut viihdytettyä itseäni tälläisellä
Zambretti ennusteella. Tämän sanotaan ennustavan yli 90% tarkkuudella seuraavan 12 tunnin sään. Tosin jostain joskus luin että jos huomiseksi ennustaa samaa säätä kuin tänään niin sekin on yli 50% varmuudella oikein.
Olen tässä koittanut myös kääntää noita ennusteita, mutta parempia käännös ideoita otetaan mielellään vastaan. Tässä tämän hetken käännösversio
A Settled fine ("Vakaa hieno ilma")
B Fine weather ("Hieno ilma")
C Becoming fine ("Tulossa hieno ilma")
D Fine, becoming less settled ("Hieno ilma, tulossa vahemman vakaa")
E Fine, possible showers ("Hieno ilma, mahdollisia kuuroja")
F Fairly fine, improving ("Melko hieno ilma, paraneva")
G Fairly fine, possible showers early ("Melko hieno ilma, mahdollisia kuuroja aluksi")
H Fairly fine, showery later ("Melko hieno ilma, kuuroittainen myohemmin")
I Showery early, improving ("Kuuroittainen aluksi, paranee illaksi")
J Changeable, mending ("Vaihteleva, selkenee")
K Fairly fine, showers likely ("Melko hieno ilma, kuuroja todennakoisesti")
L Rather unsettled clearing later ("Melko epavakaata, selkenee illaksi")
M Unsettled, probably improving ("Epavakaata, luultavasti parantuva")
N Showery, bright intervals ("Kuuroittainen, kirkasta ajoittain")
O Showery, becoming less settled ("Kuuroittainen, tulossa vahemman vakaa")
P Changeable, some rain ("Muuttuva, ajoittain sadetta")
Q Unsettled, short fine intervals ("Epavakaa, lyhyin ajoin hieno ilma")
R Unsettled, rain later ("Epavakaa, sadetta myohemmin")
S Unsettled, some rain ("Epavakaa, ajoittain sadetta")
T Mostly very unsettled ("Enimmakseen hyvin epavakaa")
U Occasional rain, worsening ("Satunnaista sadetta, heikkenee")
V Rain at times, very unsettled ("Sadetta ajoittain hyvin epavakaa")
W Rain at frequent intervals ("Sadetta toistuvasti ajoittain")
X Rain, very unsettled ("Sadetta, hyvin epavakaa")
Y Stormy, may improve ("Myrskyinen, voi parantua")
Z Stormy, much rain ("Myrskyinen, paljon sadetta")
Tämähän löytyy netistä monesta paikkaa, jossa voi kokeilla itse, esim
tämä tai
tämä.
Löysin myös php koodin
täältä, josta en tosin ymmärrä mitään. Laitanpa senkin tähän.
