There are still a few days left in the hot weather, and how long will the hot weather last

It is now the great heat of the 24 solar terms, which means that the weather is heating up now. As the saying goes: after the beginning of autumn, it is still hot for 18 days.

In other words, the temperature will drop after the heat of the 24 solar terms. In fact, after the beginning of autumn, the temperature began to drop slowly, but the temperature difference between day and night after the summer heat was large, and it was easy to perceive.

There is a saying about the weather that "cold is in Sanjiu and hot is in the middle of the volt", and now it has just entered the middle volt, and this year's mid-volt is 20 days, so the hot weather will last for about three weeks. If you come across"Autumn fool"Then it's going to be hot for a month.

Lasts until autumn.

Wait, vicious heat.

At least half a month later, it cooled down a little, and the temperature during the eleventh day was also around 37.

It's time to weaken into August, and the hottest time is coming to an end.

Cause Analysis:

1 Because after the beginning of autumn, according to the experience of previous years, there will be a short-term phenomenon of high temperatures for a period of time, which is called autumn tiger. It usually occurs at the turn of August and September and lasts about 7-15 days. After that, the weather began to get cooler in the morning and evening than in July.

2 This year's beginning of autumn will fall on August 7, 2020, which is the 18th day of the sixth month of the lunar calendar. According to the general situation, the number of tigers in autumn lasts about 7-15 days. Therefore, it is expected that the 2020 "Autumn Tiger" will end after August 14-22.

The hot weather may continue for another month or so.

Because according to the traditional Chinese lunar calendar, after the beginning of autumn (August 8), there will be 24 "autumn tigers", only after the summer (August 23), the temperature will slowly drop, generally as long as the beginning of September, it is difficult to have a high temperature of more than 35 degrees.

I don't understand, maybe it's after the summer solstice, I don't understand.

Hot weather generally starts in mid-July and ends in mid-August and lasts for about a month, although the exact number of days may vary depending on the weather phenomenon from year to year.

The main impact of high temperature weather on human health is heat stroke and death caused by cardiovascular and cerebrovascular diseases.

Under the action of excessive ambient temperature, the body temperature regulation mechanism is temporarily impaired, and heat accumulation in the body occurs, resulting in heat stroke. According to the symptoms and degree of heat stroke, it can be divided into: heat prostration, which is the mildest manifestation of heat stroke and the most common; Thermal radiation is long-term work in a high-temperature environment, resulting in dilation of blood vessels in the lower limbs, blood stasis, and fainting; Sunstroke is caused by perspiration dysfunction caused by prolonged exposure to the sun.

For patients with hypertension and cardiovascular and cerebrovascular diseases, in the environment of high temperature, humidity, no wind and low air pressure, the human body's perspiration is inhibited, the heat storage in the body is increasing, and the myocardial oxygen consumption increases, so that the cardiovascular system is in a state of tension, and the stuffiness can also lead to the expansion of human blood vessels, the increase of blood viscosity, and the symptoms of cerebral hemorrhage, cerebral infarction, and myocardial infarction are prone to occur, which may lead to death in severe cases.

I'm dizzy, big sister, who are you, Shanghai has always been so hot, and it will get hotter and hotter in the future, if you want to cool down, then come back in September.

Landlord, it may be after August 20 that it will not be so hot.

It may even be necessary to wait until autumn so that it will not be so hot.

Why is the weather so hot this year as follows:

The most important thing is that due to global warming, the greenhouse effect has intensified, resulting in the frequent occurrence of extreme bad weather, which is prone to extremely heavy precipitation and floods. It is easy to cause no rain for a long time, causing extreme drought; or cause extremely long-term hot weather, forming heat disasters; For example, the continuous precipitation in Northeast China in May, June and July this year, the freezing rain and snow disasters in Guangdong, southern Hunan and other places in early 2008, and the continuous high temperature in North China this year are the best examples.
