3. After entering the dog days, the humidity on the surface increases, the heat absorbed increases, the heat emitted every day decreases, and the heat on the surface accumulates, so it gets hotter every day. When entering the dog days, the heat accumulated on the surface reaches its peak, and the weather is the hottest. In addition, there is much rain in summer and the air humidity is high, and the heat capacity of water is far greater than that of air drying, 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 sunshine. Radiation on the ground will raise the temperature and make the weather hotter.
