Why can't the wind blow a lot of hair but can blow a ponytail?

Because the wind is not strong enough, if it is strong enough, it will certainly blow. Horsetail can make people feel full of energy, and it is also our favorite to be too lazy to wash your hair in winter! The ponytail is divided into many heights, the high ponytail is full of girlish feeling, the middle ponytail is ladylike, and the low ponytail is mature. The ponytail is not just tied casually. The key point is to tie it fluffy and full to look good.

Wind is a natural phenomenon caused by air flow, which is caused by solar radiation heat. Sunlight shines on the earth's surface, causing the surface temperature to rise, and the surface air to expand and become lighter and lighter. After the hot air rises, the cold air with low temperature flows in horizontally, and the rising air falls down because it gradually cools and becomes heavier. Because the surface temperature is high, it will heat up the air, and this airflow will produce wind. If the wind is strong, let alone a ponytail, everyone can blow it up.

Scientifically speaking, wind often refers to the horizontal motion component of air, including direction and size, that is, wind direction and wind speed; But for flight, it also includes vertical motion components, so-called vertical or ascending and descending airflow. Strong winds can move objects and their directions (mass of matter). The wind is very fast.

Wind speed refers to the horizontal distance of air flow per unit time. According to the phenomenon caused by the wind to the ground objects, the wind is divided into 13 grades, which are called wind grades. The "East Wind Level 3" that people usually hear in the weather forecast refers to the "Beaufort Wind Level". "Beaufort Wind Scale" is a wind scale determined by Francis Beaufort in England in 1805 according to the influence degree of wind on objects on the ground (or at sea), and * * * is divided into 0~ 17.
