The fog in Hangzhou continues to appear this morning. At 21:15 last night, the Hangzhou Meteorological Observatory issued a yellow warning signal for heavy fog, and there was a dense fog with visibility less than 500 meters in some areas.

According to the monitoring of the Zhejiang Provincial Meteorological Observatory, heavy fog occurred locally in some parts of northern Zhejiang and the southeast coast, among which Jiaxing, Shaoxing, Ningbo, Zhoushan and other places also appeared in dense fog.
In the morning, as the humidity decreases, the fog gradually dissipates, but it still feels like the sky is gray, which is the haze mentioned a few days ago, and suspended particulate matter fills the airFriends with respiratory tract and throat discomfort can reduce going out, and if you need to go out, you can wear a mask to avoid respiratory and cardiovascular diseases.
At 09 o'clock today, the air quality in Huzhou, Jiaxing and Shaoxing has reached moderate pollution, of which Jiaxing's AQI is 198.
As the weather warms up,The minimum temperatures in the morning are rising day by day, the lowest temperature in Hangzhou in the past three days were. 5, this morning 37. The overall warming trend is obvious.
Today's daytime maximum temperature is expected to reach 15, and with sunshine, it can be said that it is a "warm" winter.
Yesterday, the highest temperature in some parts of southern Zhejiang has broken through the "2" prefix, and it looks like it will continue today. The day after tomorrow (30th), the maximum temperature in Hangzhou will also rise to 19-20.

But after all, in the context of winter weather, cold air affects frequently, especially during the New Year's Day holidayOn the 30th and 31st, under the influence of cold air, there will be a significant cooling process, increased northerly wind and weak precipitation. However, the water vapor conditions of the whole layer are not very good, and for the main urban area, it is basically cloudy to overcast weather, and there is not much precipitation.
On the whole, the next week will continue to be sunny, the meteorological fire danger level is high, pay attention to the safety of fire and electricity, and at the same time, in winter, both the body and ** are more short of water, and the body should be replenished with water in time.
The cooling range of this cold air process is about 4-6, plus the weather is fine, and the radiation cooling is affectedThe minimum temperature will return to around 0.
Objective weather forecast for the next 7 days in the main urban area of Hangzhou.
Although the temperature is not as low as in the morning after the last cold wave, it should not be taken lightly, and everyone can wear hats, scarves, masks, etc. to keep warm when they go out.
With the arrival of cold air and the improvement of atmospheric diffusion conditions, it is expected that the haze will gradually weaken and dissipate from the evening of the 30th.
Those things about the fog
Heavy fog is one of the more common disastrous weather in China, which has the characteristics of high probability of occurrence, wide range of occurrence and large degree of harm, and has an adverse impact on civil aviation, highways, marine navigation and human health.
So, when will there be more fog in our country?The most foggy place is in **?China Weather Network has sorted out the foggy day data of 2463 national stations in China in the past 30 years, and the statistics are as follows:
In the ranking of foggy days in China's provincial capital cities,Hangzhou ranks fifth, behind Chengdu, Guiyang, Urumqi and Chongqing.
The average annual number of foggy days is 301 days in Emei Mountain, Sichuan, 299 days in Jiuxian Mountain, Fujian, and 256 days in Huangshan Mountain, Anhui.
Judging by the month-on-month data,The month with the highest number of foggy days in China is December, followed by November and January, with the least number of months being May.
This is because the type of fog in the inland areas of our country is mainly radiation fog. In autumn and winter, the nights are long, the temperature is low, and the ground radiative cooling at night is easy to condense the water vapor in the ground atmosphere, thus forming radiation fog.
