The sun is currently approaching what's known as solar maximum, the peak of our star's roughly 11-year cycle of magnetic activity.
因为目前的太阳正逐渐接近它的“活动峰年”，也就是周期约为11年的地磁活跃高峰期。
The temperature variations during a year have maxima at the poles, where the annual variation of the inflow of solar energy is also maximum.
两极地区一年温度变化极大，太阳能入射量的年变幅也极大。
