Which is colder, Hubei in March or Hunan in 65438+ 10?

With the Yangtze River as the boundary, Hubei belongs to the north and Hunan belongs to the south. It's relatively warm in the south and colder in Hubei. Latitude, Hunan is lower than Hubei, so the sunshine time in Hunan is higher than Hubei. According to this theory, Hubei is a little colder, and both belong to subtropical monsoon climate. However, from the distribution of precipitation, there is a decreasing trend from south to north, while the rainfall in Hunan is relatively abundant, so Hunan is wetter and colder than Hubei.
