"God" has been more than just a fan lately...... It's almost 12 noon today, and the real-time temperature is only in single digits, and the temperature at the same time yesterday exceeded 20 °C, which is comparable to bungee jumping!
Yesterday afternoon, the highest temperature in the urban area even rose to 25.3 °C, exceeding the 24.2 °C on December 14, 2012, and once again set the highest temperature record in mid-December since 1951.......
In the morning, a blue warning for a cold wave and a yellow warning for gales have been issued in Hangzhou! The city meteorological observatory predicts that the wind strength in various localities will be 6~8 today, and the water surface in the high mountainous areas and rivers and lakes will be even larger, reaching 8~9. Until tomorrow during the day, the sky over Hangzhou has been in a dense state of isobars, which means that the wind will be relatively strong during the day tomorrow.
Because of the wind chill effect (the greater the wind speed, the faster and more heat the human body loses, and the more people feel cold), when going out today and tomorrow, everyone must wear windproof and warm clothes, and at the same time wear scarves, gloves, hats, etc. to resist the cold wind.
In terms of temperature, the temperature in Hangzhou will continue to show a downward trend from day to night today. At 8 o'clock in the morning, the temperature in the main urban area is 9.6 °C, and it may only be 5~6 °C at 8 o'clock tonight, and the temperature will continue to decrease at night, and it will drop to about 0 °C tomorrow morning. On the morning of the 17th, the lowest point of temperature will be ushered in during the impact of this cold wave, -2~-5 °C in the plains, with freezing, and -5~-8 °C in the mountainous areas, with severe freezing!
Can it snow?
During the day today, a light rain has fallen over Hangzhou, and the question that the people of Hangzhou are concerned about is whether it can snow? Judging from the current situation, the air temperature at an altitude of 1,500 meters in Hangzhou gradually dropped to below -3 °C in the second half of the night, and at the same time, the air temperature near the ground has also gradually dropped below 2 °C. Unfortunately, however, from the second half of the night, the water vapor over Hangzhou that relied on rain (snow) quickly receded southward under the rapid northwest airflow, and completely dissipated around tomorrow morning.
Combined with the above conditions, there will be light rain in the plains from tonight to tomorrow morning, and there will be light sleet locally, and the more obvious sleet or snow can be seen in the mountains at higher altitudes. From tomorrow morning, this precipitation process will come to an end.
After the end of the cold wave process, there will be a cold air impact process on the 19th and 20th. Although the cooling range is not as large as this cold wave, because the base temperature is already relatively low, after the next cold air, the temperature will drop even lower, and it is expected that the temperature in the main urban area will be around -6 °C on the 21st, which will be much lower than normal.
From record-breaking heat to a large cold, within one day, Hangzhou people seem to have experienced "ice and fire", from early summer to autumn directly into midwinter, once again please pay attention to the drastic changes in the weather!
Zhejiang weather also reminds that due to the strong cold wave during the Hangzhou Marathon Race (17th), the temperature changes drastically, which is easy to induce respiratory tract and cardiovascular and cerebrovascular diseases, and the temperature is below 0 °C during the pre-race preparation period (5-8 o'clock), and about 0 °C during the race, the contestants have low temperature health risks, please be sure to pay attention to precautions!
Most of the central and eastern regions have turned on the quick-freezing mode
The Central Meteorological Observatory continued to issue the highest level of cold wave orange warning this morning: from 08:00 on the 15th to 08:00 on the 17th, the temperature in central Inner Mongolia, the eastern part of Northeast China, most of North China, eastern Huanghuai, most of Jianghuai, Jiangnan, eastern Southwest China, South China and other places will drop by 8~12 °C, among them, eastern Liaoning, eastern Jilin, eastern Jianghuai, most of Jiangnan, southeastern Southwest China, most of South China and other places will cool down by 14~16 °C, southeastern Jilin, eastern Liaoning, eastern Guizhou, The temperature in parts of eastern Jiangnan has dropped by more than 18°C. Most of the above areas are accompanied by 4~6 northerly winds, with gusts up to 7~9 and more than 10 locally, and 6~8 and 9~10 gusts in the eastern and southern sea areas.
The cooling range in Hangzhou has turned red!
After the influence of the cold wave, the minimum temperature 0 °C line on the morning of the 17th can be pressed south to the south of Guizhou and the north of Jiangnan, and the -10 °C line is located in the north of Huanghuai to Qinling. The minimum temperature in some areas of North China and northern Huanghuai will be close to or reach the extreme value of the same period in history.
Meteorological experts reminded that cold air will dominate the central and eastern regions in the next few days, with temperatures plummeting and low temperatures lasting for a long time.
Don't be too long-winded, the human body is prone to vasoconstriction, increased blood pressure, increased heart rate, etc., which may lead to myocardial ischemia, increased blood viscosity, induce thrombosis, and aggravate the condition of patients with cardiovascular and cerebrovascular diseases under the stimulation of low temperature. Sudden drop in temperature or low temperature weather can cause cardiovascular and cerebrovascular related diseases, respiratory system related diseases, digestive system diseases, bone and joint related diseases, etc., which must be paid special attention to.
Especially on the morning of the 17th and 18th, the minimum temperature is expected to be below 0 °C, the elderly should try to go out less and exercise in the morning, and patients with cardiovascular disease must not go directly from indoors to outdoors, but should first let the body adapt to it in the corridor and other places, and wear hats, scarves, etc. to keep warm.
