Refers to the short-term high temperature weather in beginning of autumn (around August 8th). It usually happens at the turn of August and September and lasts about 7- 15 days. Meteorology means that the highest temperature is above 35℃ for five consecutive days after the summer solar term. The reason for this kind of weather is that the subtropical high retreating to the south has once again controlled the Jianghuai and its nearby areas, resulting in fine weather, strong solar radiation and the reappearance of hot summer weather, which makes people feel sultry and uncomfortable, so it is called "autumn tiger".
