The foggy weather in Shandong lasted all morning.

According to the yellow fog warning issued by 6543813, there are strong fog in some areas of 7 provinces, including Shandong and Hebei, and especially strong fog in some areas. Specifically, the Central Meteorological Observatory continued to issue a foggy yellow warning at 06: 00 on October 3, 65438/KLOC-0. It is estimated that there will be fog in parts of southeastern Hebei, western Shandong, northern Jiangsu, central and northern Anhui, southern Henan, central Hubei, northern Hunan, southwestern Shaanxi, eastern Sichuan Basin and central Liaoning from the morning of13.

Reasons for foggy weather:

1, radiation cooling: at night, a lot of heat is lost on the ground, which leads to the decrease of the ground temperature. The air near the ground also cools down, and the water vapor in the air condenses into water droplets, forming a radiation fog. This kind of fog usually forms on clear and windless nights and often appears in the morning.

2. Sea-land breeze: In coastal areas, the temperature of the ocean changes little, while the temperature of the land changes greatly. At night, the land radiation cools down quickly, and the water vapor in the air condenses to form fog. During the day, the land heats up faster and the fog dissipates.

3. Cooling process: In the process of cold air going south, the temperature gradually decreases, and the water vapor in the air condenses into water droplets and forms fog. This fog is usually accompanied by precipitation and cooling.

4. Water source: Close to lakes, rivers and other waters, there is more water vapor in the air, which is conducive to the formation of foggy weather.
