The yellow in the clue means dog days in English.

The topic is July 12 Taobao daily guess. According to the clue, the yellow English is "dog day", which means dog days.

The concept of dog days:

The dog days, which appear between the summer heat and the summer heat, are the period with the highest temperature, the highest humidity and the most severe sultry heat in a year. Three volts can be divided into initial, middle and final volts, and its date is determined by the coordination of 24 solar terms and the dates of dry and branch. After "entering the volt", many places in the country will enter the continuous high temperature mode.

The traditional almanac stipulates that "counting from the third Geng day in summer", that is to say, "counting down from the summer day until the third Geng day" is about to begin to dormant. The "Geng Day" here refers to the days prefixed with "Geng" in the ancient "Ganzhi Jiri Law". "crouching" means being forced to hide underground; This also means that it is too hot to move.

The length of dog days mainly lies in the difference between middle and next days. Because the third Geng day (the first autumn) after the summer solstice solar term occurs at different times every year, the number of days in the middle autumn is also different. The incubation time is long or short, which may be 10 day or 20 days. So there are two situations: some years are 30 days in dog days, and some years are 40 days.

The hottest reason in dog days:

After lodging, the surface humidity increases, and the heat absorbed every day is more, but the heat emitted is less, and the heat on the surface is accumulated. So it gets hotter every day, and when it enters the dog days, the accumulated heat on the ground reaches its peak and the weather is the hottest. In addition, there is much rain in summer, the air humidity is high, and the heat capacity of water is much greater than that of dry air, which is also an important reason for the sultry weather.

The subtropical high intensified in July and August. Under the control of the subtropical high, the descending airflow inside the high makes the weather clear and cloudy, which is beneficial to the sunshine, the ground radiation heats up and the weather is hotter.
