Why can't wind blow a lot of hair but a ponytail?
Because the wind is not strong enough, if the wind is strong enough, it will definitely blow. Ponytail can make people feel full of vitality, and it is also our favorite that we are too lazy to wash our hair in winter! Ponytails are divided into many heights, with high ponytails full of girls' feelings, medium ponytails with ladies' temperament, and low ponytails with mature atmosphere. 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, which makes the surface temperature rise, and the air on the surface becomes lighter and rises when heated and expanded. After the hot air rises, the cold air with low temperature flows in horizontally, and the rising air falls down due to the gradual cooling and heavier. Because the surface temperature is higher, it will heat the air to rise, and this air flow will generate wind. If the wind is strong, let alone a ponytail, everyone can blow it up.
From a scientific point of view, wind often refers to the horizontal motion component of air, including direction and magnitude, that is, wind direction and wind speed; But for flight, it also includes vertical motion components, that is, the so-called vertical or ascending and descending airflow. Strong winds can move objects and the direction of objects (material mass). The wind is very fast.
wind speed refers to the horizontal distance that air flows in unit time. According to the phenomenon caused by the wind to the objects on the ground, the size of the wind is divided into 13 grades, which are called wind grades. And what people usually hear in the weather forecast, such as "East Wind Level 3", refers to "Beaufort Wind Level". "Beaufort Wind Scale" is a wind scale determined by Francis Beaufort in 185 according to the degree of influence of wind on objects on the ground (or sea), and * * * is divided into ~17 grades.
