They form due to convection in Jupiter's atmosphere.

它们是由木星气对流产生。

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

传导、对流和辐射。

Convection, the heating principle on which most earth-based ovens run, doesn't work in orbit.

地球数烤箱加热原理是对流，但在太空里这派不用场。

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

我们将面包放入对流恒温烤箱，用350度烤。

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，里面冻结了。

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。

Convection is the mass movement of a fluid: hot water rising, for example.

对流是液体整体移，比如热水升。

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。

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.

正如你可能知道那样，恒星是巨聚变力对流炉，其核心处燃烧温度很高，以至于非常原子会分裂并形成更原子。

The movements occur not just laterally as the Earth's plates move across the surface, but up and down as well, as rocks rise and fall under the churning process known as convection.

移不仅真发生，就像地球板块做平面移那样，而且还下移，就像岩石在所谓对流作用之下时起时伏。

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食物时，你把空气吹到接近你体温地方——平均 98.6 度——并用它来代替温暖空气，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.

这个半球形形状捕捉热量，将其发散回去，并产生对流效应，从而提高你可以从有限燃料中获得温度。

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.

像蜡烛方热空气一样，温暖岩石对流升几百万后，将热量更均匀地扩散到整个地球。

Convection currents help warm water from the equator get farther north, while colder water from the north is able to cool hotter areas down south.

洋流有助于推赤道地区温水向北流，而来自北方冷海水向赤道流以降温。

They occur when convection currents created by the intense heat whip across the desert surface, causing sand and dust to become airborne.

当炽烈热浪与沙漠表面 猛烈摩擦产生热对流这时就会发生沙尘暴 沙子和灰尘就会漫天飞舞。

Less dense molten rock travels from the core to the surface, where it then cools and returns — a process called convection.

密度较小熔融岩石从核心移到地表，然后在那里冷却并返回——这个过程被称为对流。

Novopangea is merely what would happen if the convection currents in the mantle carry on exactly as they are and don't change.

如果地幔中对流保持现状不变，就会形成新盘古陆。

To me, I know it's a convection oven, the whole thing, but it kind of feels like a microwave.

对我来说，我知道这是一个对流烤箱，但整个东西看来，它还是有点像一个微波炉。

Conduction is the transfer of heat between solid objects, convection uses the movement of fluids, while radiation relies on electromagnetic waves.

传导指是两个固体之间热量转移，对流运用流体运，辐射利用电磁波。

All that water vapor rising from the forest feeds moisture-laden clouds while also causing convection.

这些从森林中升起水蒸气，培养了潮湿云朵，同时也导致了对流。
