They form due to convection in Jupiter's atmosphere.

它们是由木星大气的对流产生的。

There are three main ways by which heat transfer occurs, conduction, convection and radiation.

传导、对流和辐射。

When you see the top of a storm cloud flattening out into the classic anvil shape, you are looking at the boundary between the troposphere and stratosphere.

当你看到一片雷雨云的顶端扩展成典型的砧形，你是在看着对流层和平疏层的交界之处。

Just beneath the surface is the convective zone.

层的正下方是对流区。

Convectional rain is experienced at the end of a hot summer day, like when the air feels heavy and we can tell a storm is brewing.

在炎热的夏天结束时，会经历对流雨，空气会变得很重，我们可以感觉到暴风雨就要来了。

We bake our croissants off at 350 degrees in a convection oven.

我们将包放入对流恒温烤箱，用350度烤。

This mammoth skyscraper will extend for more than 12 miles from top to bottom, meaning its “roof” or top will be somewhere in the troposphere, far above the Earth's surface.

这座巨大的摩天大楼将从上到下延伸超过12英里，这味着它的“屋顶”或顶部将位于对流层的某处，远离地。

The internal convection currents that drive geology stop and, in general, it just freezes up.

行星内部没有了地质对流，总而言之，里冻结了。

Not so the cumulonimbus, the tallest of all clouds, they extend way up into the troposphere and these are the ones that produce lightning thunder, heavy rain, strong winds, and tornadoes beware the cumulonimbus.

但积雨云却不是这样，积雨云是所有云中最高的，它们向上延伸到对流层，这些云会产生闪电，暴雨，强风和龙卷风小心积雨云。

Two months ago Disney began a corporate restructuring to increase its focus on streaming.

两个月前，迪士尼开始了企业重组，并加大了对流媒体的关注。

Cooling pumps can be replaced by natural convection currents, for instance.

例如，冷却泵可以用自然对流代替。

As soon as this warning convection clears out, we will try to cover very quickly.

在预警对流清除以后，我们要迅速行动。

That causes the soup of pollutants in the troposphere to become more concentrated, says Sinha.

这导致对流层中的污染物更加集中，辛哈说。

The powerful winds triggered alerts for five types of meteorological disasters: gales, snowstorms, sandstorms, torrential rain and severe convective weather, which refers to sudden and destructive conditions such as thunderstorms, hail, strong winds and localized heavy rain.

此次强风触发了五类气象灾害预警：大风、暴雪、沙尘暴、暴雨和强对流天气（指雷暴、冰雹、强风、局地短时强降水等突发性灾害天气）。

Stars, as you probably know are enormous fusion powered convection ovens that burn so hot at their cores that very large atoms can smash together and form even larger atoms.

正如你可能知道的那样，恒星是巨大的聚变动力对流炉，其核心处燃烧温度很高，以至于非常大的原子会分裂并形成更大的原子。

When you blow air over piping hot food, you're sending air close to your body temperature—an average of 98.6 degrees—and using it to replace warmer air in a process known as convection.

当你把空气吹到滚烫的食物上时，你把空气吹到接近你体温的地方——平均 98.6 度——并用它来代替温暖的空气，这个过程被称为对流。

The semi-spherical shape captures heat, radiates it back and creates a convection effect that just increases the temperature that you can get from a limited amount of fuel.

这个半形的形状捕捉热量，将其发散回去，并产生对流效应，从而提高你可以从有限的燃料中获得的温度。

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，它们将不足以克服气体的对流混合，因而太阳黑子将完全消失。

And like the hot air above a candle, the warm rock rises in convection currents over millions of years, spreading heat more evenly throughout the planet.

像蜡烛上方的热空气一样，温暖的岩石对流上升几百万年后，将热量更均匀地扩散到整个地上。

The denser saltwater flows beneath the freshwater, where it remains permanently, making the Black Sea the world's largest meromictic — or un-mixing — basin.

密度较高的咸水在淡水底下流动，且会永远待在下，让黑海成为世界上最大的局部循环——不完全对流——海湾。
