सर्दियों का स्मॉग, दुनिया भर में महीने-दर-महीने
कोयले का धुआँ और घाटी में फँसी हवा; दिक्कत ठंड नहीं, हवा है।
यह चेतावनी का पेज है, सिफ़ारिश का नहीं। SeasonMap पर सर्दियों का स्मॉग 38 जगहों को छूता है; नीचे दिए महीने वे हैं जिनमें जोखिम का दौर खुला रहता है — इनमें से ज़्यादातर हफ़्ते चुपचाप गुज़र जाते हैं, और हर जगह के आगे दिया स्कोर वही आम जलवायु स्कोर है, ख़तरे समेत।
यह कब चलता है
