Cold air is coming! Zibo needs to cool down. The lowest temperature is 1 1℃. The public should add clothes in time according to the weather changes to guard against colds.

On the 3rd, Zibo was cloudy with light rain. On the 4th, there may be weak precipitation locally. On 5-6 days, there were more clouds and the temperature dropped significantly. From 7th to 9th, cloudy weather dominated. Specifically: there was light rain in the cloudy part on the 3 rd, and the south wind turned to southwest wind 2 ~ 3,18 ~ 27℃; On the 4th, it turned cloudy to light rain, the southwest wind changed from 2 ~ 3 to 3 ~ 4, and the temperature was 15 ~ 26℃.

On the 5th, it was cloudy, and the northeast wind turned to the north wind by 2 ~ 3 grades, 1 1 ~ 23℃.

The public should continue to pay attention to early warning and forecasting information, plan their trips reasonably, and pay attention to cold and warmth.

The sources of cold air mainly include the following aspects:

1, high latitude area

Located in the polar and cold regions at high latitudes, the temperature is relatively low, forming a cold air mass. When these cold air masses move to low latitudes, they will bring cold air.

2. High altitude areas

Due to the high altitude, the temperature in high altitude areas is usually low, forming a cold air mass. When these cold air masses move to low altitude areas, they will also bring cold air.

3. Polar vortex

Polar vortex is a large-scale low-pressure system formed in polar regions, which will bring cold polar air into mid-latitude regions and form cold air.

4. cold front

Cold front is the front where cold and warm air meet. When the cold front moves, it will bring cold air into relatively warm areas.

5, high-altitude jet stream

High-altitude jet refers to the airflow that flows faster in the middle latitude of the upper atmosphere, which will bring cold air from high latitude to low latitude.
