What is "forward warming"

The cooling is imminent, but Xiamen is as hot as early summer, what is the reason for this? According to meteorological experts, in fact, this is a front-forward warming. This refers to the weather phenomenon that before the arrival of cold air, the temperature abnormally warms, sometimes even sweltering, making people have the illusion of seasonal change.

The reason is that before the arrival of cold air, the front is controlled by warm and humid airflow, and as the cold front approaches, the cold air quickly squeezes the originally dominant heating group into a narrow area to gather and heat up; in addition, the cold air generally blows south wind before the arrival, which will also aggravate the heating.
