极光发生在大气层中什么位置,请问极光出现在大气层的哪一层?
据和记百科网站「陌上吟归雪」消息,近日,极光发生在大气层中什么位置,请问极光出现在大气层的哪一层?引发热议,极光发生在大气层中什么位置同样引起许多争议,对此众网友各抒己见。但到底是怎么回事呢?和记百科为您解答。
极光出现在大气层的电离层,是由于来自磁层和太阳风的带电高能粒子被地磁场导引带进地球大气层,并与高层大气(热层)中的原子碰撞造成的发光现象。极光常出现于纬度靠近地磁极地区上空,一般呈带状、弧状、幕状、放射状。
极光基本分类:
1、按照极光的形态分类,可分为匀光弧极光、射线式光柱极光、射线式光弧光带极光、帘幕状极光、极光冕等。
2、按照极光观测的电磁波波段,可分为光学极光、无线电极光等。
3、按激光激发粒子类型,可分为电子极光、质子极光等。
4、按照极光发生区域,可分为极盖极光、极光带极光 、中纬极光红弧等。
答:电离层。极光出现在大气层的电离层。极光是一种绚丽多彩的等离子体现象,其发生是由于太阳带电粒子流进入地球磁场,在地球南北两极附近地区的高空,夜间出现的灿烂美丽的光辉。
【英文介绍/For English】:
Auroras occur in the ionosphere of the atmosphere and are caused by the glowing phenomenon caused by charged energetic particles from the magnetosphere and the solar wind being guided into the Earths atmosphere by the geomagnetic field and colliding with atoms in the upper atmosphere (thermosphere). Auroras often appear in the sky above the latitudes close to the geomagnetic poles, generally in the shape of bands, arcs, curtains, and radials.
Aurora basic classification:
1. According to the shape of aurora, it can be divided into uniform arc aurora, ray beam aurora, ray arc aurora, curtain aurora, aurora corona, etc.
2. According to the electromagnetic wave band of aurora observation, it can be divided into optical aurora, wireless electrode light, etc.
3. According to the type of laser excitation particles, it can be divided into electron aurora, proton aurora, etc.
4. According to the area where the aurora occurs, it can be divided into polar cover aurora, aurora belt aurora, mid-latitude aurora red arc, etc.
