What is the reason for the low temperatures in Quanzhou recently?

Continued low temperatures are related to El Ni?o

What is the cause of persistent rainy and low temperature weather? Many places in the south are also experiencing widespread rainy weather. This is mainly because cold air activities are still frequent, and the southwest warm and humid air flow is also strengthening. The two forces are equal, resulting in frequent rainfall.

It’s May, why is the cold air still so strong? It is indeed unusual for the cold air to be so active this season. This is due to the unusually large amount of snow cover in the autumn and winter in Eurasia last year, coupled with the abnormal southward expansion of polar cold air, which resulted in abnormally active cold air in the mid- and high latitudes, and its lingering influence has not diminished to this day.

In addition, El Ni?o is also an important cause of abnormal weather. El Ni?o refers to an abnormally warm sea temperature event in the central and eastern equatorial Pacific that has occurred since June last year. Affected by this, the subtropical high in the western Pacific is generally stronger. Therefore, warm and moist air flows continue to be transported to the central and eastern regions of my country and meet the cold air. Later, it caused widespread rainy weather in many parts of our country.
