What does it mean to return to Nantian, Guangdong?

Guangdong Huinantian refers to the phenomenon of rising temperature and humidity every spring, which is the name of a weather phenomenon in southern China.

South China belongs to a typical maritime subtropical monsoon climate. Therefore, from March to April every year, warm and humid air from the South China Sea in China meets cold air from the north of China, forming a quasi-static front in Lingnan, which makes the weather in South China changeable and very humid, with light rain or fog in between, resulting in the phenomenon of returning to the south. Some cold objects begin to condense after encountering warm and humid airflow, forming water droplets on the surface of the objects.

Returning to Nantian is a phenomenon of warmer weather, which generally appears in February and March in spring. The main reason is that after the cold air leaves, the warm and humid airflow quickly counterattacks, resulting in an increase in temperature and air humidity. Some cold objects are easy to produce water droplets when they encounter warm and humid airflow. The tropic of cancer in the south is more serious, which is related to the sea and humid air in the south.
