Why is it so hot in autumn in Wuhan this year?

The influence of weather system and urban heat island effect.

1, weather system. After the autumn, the subtropical high in the western Pacific, which controls China, began to move southward gradually, but remained at a high position, which made the weather characteristics of cloudy and strong sunshine in Wuhan last.

2. Heat island effect. With the acceleration of urbanization and the continuous expansion of urban area, urban buildings, roads and other hard floors absorb a lot of solar radiation and release a lot of heat, which further increases the urban temperature in Wuhan.
