蝦夷方言藻汐草

All three dictionaries give warm for popke, directly matching 暖 and the recorded ポプケ. Tamura distinguishes the person/object predicate from weather sir-popke, while noting the range of ordinary warmth. A 1969 narrative describes popke rera, warm wind. The companion table has the different heading 暑; the source pair 暖／ポプケ has direct lexical support.
