Why is autumn tiger so hot?

The reason for the formation of autumn tiger is that the western Pacific subtropical high that controls China gradually moves southward in autumn, but moves northward. Under the control of this high pressure, it turned cloudy and sunny locally, with strong solar radiation and rising temperature. This regenerative weather is called "old woman summer" weather in Europe and "Indian summer" weather in North America. Beginning of autumn just now.

"Autumn" includes beginning of autumn, Chushu, Bailu, Autumnal Equinox, Cold Dew and First Frost. After autumn, the rain is decreasing day by day, and the air humidity is lower than the limit needed by people's life (the relative humidity is 70%), so the weather is dry, the vegetation withers and people feel dry. Seeing dryness due to dryness injuring body fluid. Dryness is the main qi in autumn and belongs to yang evil. Diseases caused by dryness are warm (early autumn) and cool and dry autumn tiger (late autumn).

There is still high temperature in summer in early autumn, sunny and rainy, and the climate is dry. At this time, the evil dryness is warm and dry, which mainly hurts yin, that is, body fluid. Symptoms are dry skin, chapped eyes, less red tongue and body fluid, dry hair, red and yellow urine, dry stool, dry mouth and nasopharynx, chest pain, dry cough and scanty sputum, bloodshot sputum, and even moderate to high fever.
