Who cools the fastest in Hefei or Nanjing?

The cooling rate is influenced by many factors, such as climate, topography and latitude. Generally speaking, the temperature in high latitudes will drop faster than that in low latitudes in winter, because high latitudes receive less solar radiation, while low latitudes receive more solar radiation.

The latitudes of Hefei and Nanjing are similar, so the main difference in cooling speed between the two places lies in other factors. In summer, because Nanjing is a plain city with hot air, and Hefei is located in a mountainous area with forest cover, the temperature drop in Nanjing may be slower than that in Hefei.

In winter, Nanjing is located along the Yangtze River, which is greatly influenced by the ocean, while Hefei is located inland, so Nanjing may cool down faster than Hefei.

Generally speaking, it is impossible to clearly judge which of Hefei and Nanjing has the fastest cooling, because it depends on the specific season and weather conditions.
