To a greater extent than was formerly thought to be the case the monsoons appear to be in the nature of various kinds and degrees of modification of the general planetary wind system.

季风看来具有受行星总风系的不同性质和不同程度的影响，这比以往更为可信。

The resulting stream of charged particles, called the polar wind (not to be confused with the planetary wind), accounts for 10 to 15 percent of Earth's hydrogen loss and almost its entire helium leak.

由此形成的带电粒子流，就叫做“极地风”(polar wind)，可占地球氢元素泄漏过程的10 ~ 15%，而几乎所有的氦气就是以这种方式脱离地球的。

Louis Friedman, executive director of the Planetary Society, says that the sails must be launched to test them, because there is no solar wind in Earth's atmosphere.

行星社执行官Louis Fried man告诫道，太阳帆必须发射升空才能进行实验，因为在地球大气中不存在太阳风。
