A white froth is present on the lake 's surface around the plume when the convective activity momentarily increases .

对流活动加剧的瞬间，某种白色的气泡在卷流附近的湖面泛起。

When the air close to the mushrooming convective clouds is near saturation , additional lift from the fast-rising current causes the air column to become thoroughly saturated .

当靠近突然扩大对流云的空气接近饱和时，由于快速上升的气流所引起的附加提升，使气柱变得完全饱和。

The new images show that the clouds are actually vigorous convective storms that form yet another distinct , inner ring .

新图像显示，那些云团实际上是强有力的对流风暴，对流风暴又形成了另外一个清晰的内环。

Below a certain threshold , they will not be strong enough to overcome the convective mixing of the gas at the surface , and spots will disappear altogether .

低于一定的临界值的话，它们将不足以克服表面气体的对流混合，因而太阳黑子将完全消失。

The solar interior , from the inside out , is made up of the core , radiative zone and the convective zone .

太阳的内部，从内到外，依次分为核心、辐射区和对流区。
