Genom denna litteraturstudie undersöktes hur “bra” SEAS5 prognoser är för Europa utifrån allmänhetens perspektiv, för temperatur och delvis nederbörd under sommar och vinter. En “bra” prognos definieras här som en prognos som relativt pålitligt och träffsäkert kan besvara vanliga frågeställningar från allmänheten. SEAS5 har överlag bra reliability (pålitlighet) för marknära temperatur i Europa, men det är svårt att veta hur detta skiljer mellan olika platser. Dessutom förutspår SEAS5 sällan händelser med höga procentsatser, vilket gör den höga pålitligheten mindre användbar. I termer av skill (träffsäkerhet) varierar det mycket mellan säsong och plats. Överlag är
skill-nivån på gränsen till synoptiskt användbar, med den högsta skill-nivån i södra och sydöstra Europa under sommaren följt av norra Europa under vintern. Ganska stora områden av Europa har ingen skill (inte bättre än en klimatologisk prognos) under vissa förhållanden och i framförallt delar av Frankrike tycks det vara så året runt. Sammanfattningsvis uppfylls kraven för en “bra” prognos av marknära
temperatur bara fläckvist beroende på säsong och plats. Prognoser för nederbörd är generellt inte tillräckligt “bra”, varken i skill eller i reliability, oavsett årstid och plats. P.g.a. många komplexa aspekter inom fysiken i klimatsystemet på S2S-tidsskalor och skapande av S2S-produkter kommer det ta tid innan S2S-prognoser uppfyller
