When is it hottest? When does it start to get hot

After the summer solstice, although the days are getting shorter and the nights are getting longer, the days are still longer than the nights, and the ground still absorbs more heat than it emits every day, and the temperature near the ground is getting higher day by day. to"Dog days"During this period, the ground absorbs almost less heat than it emits, and the weather is at its hottest. After that, the ground begins to absorb less heat than the ground emits and the temperature slowly drops.

So the hottest time of the year generally occurs on the summer solstice"Dog days"。The Great Heat solar term is the hottest solar term of the year, and the ancient book "Twenty-four Solar Terms" says: "The Great Heat is the hottest of the heat."

This is enough to illustrate how hot this solar term is. The reason why the heat is extremely hot during the "Great Heat" period is that since the beginning of summer, the ground has absorbed more heat from the sunlight during the day than at night, and the heat has been accumulating, and the accumulated heat reaches its peak during the Great Heat, so the Great Heat is the hottest.

The hottest time of the day The sunlight hits the ground, which heats the ground, and the heat absorbed by the ground is then released to warm the air, and the temperature of the air is mainly obtained indirectly from the ground. Although at noon in summer, the sunlight hits the ground closest to direct light, and the ground and air are strongly heated, but the heat released by the ground is less than the heat of the sun, so this is not the hottest time. After noon, the ground temperature can continue to rise, and the ground temperature can only rise to the maximum when the heat released by the ground is equal to the heat of the sun; And the increase in the temperature near the ground must be obtained from the heat released from the ground, and it all takes time, so the hottest time in summer is not at noon, but at two or three o'clock in the afternoon.

On the summer solstice, the sun reaches the Tropic of Cancer, the Tropic of Capricorn, the hottest in the Northern Hemisphere.

It's about two o'clock in the afternoon.

August-SeptemberAutumn tigers are also hot enough.

At two or three o'clock in the afternoon in the summer, the earth is dissipating.

The hottest time is from mid-July to August.

It's hottest when you're in the heat.

May.

Summer in China starts from the beginning of summer, and the time is in early May, so the weather begins to get hotter in May, and the temperature in the south is higher than in the north.

From the end of June, it begins to enter the hottest part of summer and lasts until the end of September. Especially in the summer, the dog days from mid-July to mid-August are particularly hot. Summer is hot until September, because after the beginning of autumn, there will be a short-term phenomenon of high weather, called autumn tiger.

It usually occurs at the turn of August and September and lasts for about 7-15 days. After that, the weather began to get cooler in the morning and evening than in July. Summer starts to get hot from what month Summer starts to heat from May.

In terms of solar terms, summer in our country starts from the beginning of summer, the beginning of summer solar terms herald the arrival of summer, the time is in early May, the southern region begins to feel the summer atmosphere at the end of May, and the temperature in the north is much lower than that in the south, which can only be said to be relatively warm.

Because the southeast wind prevails in China in summer, it first landed in the southern part of China, so the southern region is more wild and enters the rainy season early. When is the hottest summer July to August is the hottest summer months.

The hottest time of summer is from mid-July to mid-August, which is also known as the "dog days".

In terms of the hottest solar terms, the Great Summer Solar Term is the hottest solar term of the year.

July is one of the hottest months of the year. Summer is the hottest season of the year, with the hottest months usually July and August. July and August are dog days, such as the high temperature and heat that occur on the dog days of the wheel shortage, and it is the hottest, humid and hot day of the year.

The so-called 'dog days' refer to the 'dog days' of the lunar calendar, which is the hottest period of the year. "Volt" means that the weather is too hot to move. This season is characterized by sunny days, clear blue skies, and high temperatures.

Summary. The hottest months are July and August.

The hottest months are July and August.

After the summer solstice, the position of the sun gradually moves southward, although the sun irradiation time is getting shorter and farther, and the radiant heat is gradually decreasing, but the earth still absorbs more heat than it loses every day.

The hottest time of the year is dog days, and the hottest time of the day is between 2 and 4 p.m. Dog days mostly occur between mid-July and mid-August in the Gregorian calendar, so the hottest month of the year in most parts of the country is July-early August; Near-surface temperatures reach their highest at 2 p.m., so the hottest time of the day is between 2 p.m. and 4 p.m.

In general, heat refers to a temperature that is higher than the general feeling of warmth or warmth.

Exactly when it starts to heat depends on the location, season, and a variety of other factors.

For example, in the summer months, the temperature in most parts of Liangluo in China will exceed 30, so it starts to get hot.

In winter, the temperature in some parts of Japan is very low, and if you don't take into account the wind chill effect, the temperature that usually starts to heat is around 20.

Different industries have different definitions of starting hot.

For example, if you want to define a hot temperature, then according to the National Weather Service regulations, when the average temperature reaches 35 or more, the high temperature lasts for more than 3 days is defined as hot.

Summary. Gregorian Month Of the twelve months of the year, the hottest month should be the month of the Gregorian calendar. Because the month is in the dog days, which are the hottest time of the year, the month of the solar calendar is considered the hottest time of the year.

Although the summer solstice is the day with the longest solar irradiation time in the northern hemisphere and the shortest distance between the sun and the ground, so the solar radiation heat obtained is the most day of the year, but the heat accumulated by the earth has not reached the most at this time, so the weather is not the hottest time at the summer solstice. After the summer solstice, the position of the sun gradually shifted southward, although the sun irradiated time is getting shorter and farther away, and the radiant heat is gradually decreasing, but the earth still absorbs more heat than it loses every day, and the heat accumulates more and more, so the month after the summer solstice is the hottest time in the northern hemisphere.

Gregorian Month Of the twelve months of the year, the hottest month should be the month of the Gregorian calendar. Because the month is in the dog days phase, and the dog days are the hottest time of the year, the month of the solar calendar is considered the hottest time of the year. Although the summer solstice is the day when the sun shines the longest in the northern hemisphere and the sun is the shortest distance from the ground, the solar radiation heat is the most day of the year, but the heat accumulated by the earth has not reached the maximum at this time, so the weather is not the hottest time at the summer solstice.

After the summer solstice, the position of the sun gradually shifted southward, although the sun irradiation time is shortening day by day, the distance is getting farther and farther, and the radiant heat gradually decreases, but the earth still absorbs more heat than it loses every day, and the heat accumulates, and the heat is getting bigger and bigger, so the month after the summer solstice is the hottest time in the northern hemisphere.

2022 Dog Days Schedule: July 16, 2022 - July 25, 2022, a total of 10 days; 2 volts (medium volts): July 26, 2022 - August 14, 2022, a total of 20 days; Three Dog (Last) Qingbi:

"Fu" means that the yin is forced by the yang to hide underground, and the three dogs are divided into the beginning, the middle and the end, and its date is determined by the solar terms of the Ganzhi calendar and the date of the Ganzhi period.
