Explain why the temperature is similar in spring and autumn, but things are more prone to mildew in spring.

Generally, the humidity is high in spring, and there is much rain and high air humidity in this season.

Many articles are difficult to keep dry, and humid environment is a hotbed of mold, so articles are easy to get moldy. In spring, the cold temperature in winter gradually rises, and the water vapor condensed at low temperature in winter slowly melts and evaporates, and the air humidity increases, so that indoor and outdoor will be wet and sticky, and articles are prone to mildew.

Spring characteristics

Spring, also known as spring, is the first of the four seasons, which refers to the period from beginning of spring to long summer, including solar terms such as beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain.

Spring is the season when everything revives. The Gregorian calendar in the northern hemisphere is from March to May, and in the southern hemisphere it is from late September to late February of 12. Meteorology begins with the average temperature of 10℃ for five consecutive days. In spring, the climate is warm and mild, and there is rainfall in most parts of inland China. Everything is animistic, the climate is changeable, and it is warm and cold at first.

In spring, the northern hemisphere of the earth began to tilt towards the sun, receiving more and more direct sunlight, so the temperature began to rise. In spring, plants begin to sprout and grow, and many flowers bloom. Hibernating animals wake up, many animals with eggs for the winter hatch, and birds begin to migrate, leaving the wintering ground for breeding grounds.

Many animals are in estrus during this period, so China also calls spring the season when everything recovers. Because hot air began to move northward, while cold air often lingered, in addition, the temperatures of land, water and air all rose at different speeds.

In spring, many places in the south of China are rainy, but in the north of China, there will be less rain and less dry. There are often strong storms in Europe and tornadoes in North America.
