The delicacies of the summer heat include duck meat, chicken head rice, potatoes, etc.

1. Duck meat "give ducks when the heat is over, and everyone will be free of disease."

Eating duck during the summer heat is an old folk tradition.

Because this time of year is preceded by the heat of summer and followed by the coolness of autumn, the transition in diet must not only clear away the heat, but also properly protect against the cold.

2. Chicken head rice is over the heat, which is a good time for chicken head rice to be put on the market in large quantities.

"Eat this treasure during the summer heat, and you will be free of illness for half a year!" Summer is gone and autumn is coming, and people are prone to depression in autumn.

The older generation likes to simmer chicken head rice in sugar water to cope with the autumn dryness. Chicken head rice, also known as Gorgon fruit, is grown in swamps and lakes north and south of the Yangtze River, but Suzhou Real Estate's Nan Gorgon is particularly famous.

3. Potatoes are exposed to heat, which is a homonym for “storing potatoes” and “eating potatoes”.

In Hunan, there is a custom of eating potatoes during the summer heat.

"Potatoes grow during the summer heat." Eat the stem tips of sweet potatoes before the summer heat. After the summer heat, the focus of sweet potato growth begins to shift underground.

Weather changes at the end of summer: End of heat, which means "out of heat", the high temperature will gradually subside.

After the summer heat, the direct sun point continues to move southward, solar radiation weakens, and the subtropical high pressure retreats southward. As the height of the sun continues to decrease, the heat it brings also weakens.

The end of the summer season means that the hot and unbearable weather has come to an end. Although the weather is still hot during this period, it is already on a downward trend.

The subsidence of summer heat is a slow process. It does not mean that the weather becomes cooler immediately after the summer heat drops. It usually takes until after the white dew for the real coolness to begin.

After the summer heat, the temperature gradually drops and the temperature difference between day and night gradually increases, but the daytime temperature is still high.

The reasons for this phenomenon are: first, the direct point of the sun continues to move southward, and solar radiation weakens; second, the subtropical high pressure retreats southward in a leapfrog manner, and the Mongolian cold high pressure begins to show its strength.

Although the subtropical high pressure has made great strides to retreat southward after the end of summer, it will never give up its dominance and easily retreat to the sea in the Western Pacific.

In the southern areas controlled by it, high temperatures are often experienced again at the end of the summer heat. This is the short-term hot weather "autumn tiger".

The length of autumn tiger season varies every year, generally lasting from half a month to two months.

The reason for the formation of autumn tiger is that the western Pacific subtropical high pressure that controls China gradually moves southward in autumn, but then moves northward. Under the control of the subtropical high pressure, it becomes clear and cloudy, with strong sunshine and rising temperatures.
