Acum am verificat si eu rezultatele.
Pentru a obtine "Tmed" ai facut media celor 24 de temperaturi orare? Vad ca pe
http://www.ogimet.com/resynops.phtml e putin diferita... dar nu stiu cum o calculeaza acolo. Imi pare rau ca nu am timp acum sa verific si eu media.
In afara de asta mai am doar o mica complectare:
- Precipitatiile la Arad: 8.2 mm
Restul e ok! O sa calculez punctajele deseara cand ajung acasa!
la arad 8.0 e totalul de prec pe 24h...fara dubii, scos din synop de azi ora 6 UTC...apare la final grupa 70080
Tmed pe ogimet il calculeaza pe interval diferit de al nostru...de asta e putin altfel...eu iau in calcul 8 valori-de la orele 09,12,15,18,21,00,03,06 (UTC)...apoi le fac media aritmetica...
doodoo esti sigur ca in SYNOP-ul de la ora 18:00 UTC sunt precipitatiile de pe ultimele 24 de ore?
Poate ca programelul meu de decodare scrie gresit, dar uite cum traduce SYNOP-urile de duminica de la 18.00 UTC si de luni de la 6.00 UTC de la Arad:
