But they face many physiological problems – problems relating to how the human body functions, such as the bends – a painful medical condition caused by returning too quickly to atmospheric pressure – the Earth's usual air pressure.

但他们面临许多生理——与体机能有关的，如减压病——因太快返回大气压强下而导致的一种痛苦的身体状况，大气压强是指地球正常气压。

It happens when there`s a rapid drop in atmospheric pressure that causes the storm to become very intense very quickly.

Since the atmospheric pressure is a lot lower in high altitudes, it would be freezing cold if you were flying above the clouds.

在高海拔地区，由于大气压力很小，气温会降低。如果你在云层上面飞行。

Fortunately, the gas produced in abundance by the volcanoes maintained enough of an atmospheric pressure for Earth to be able to hold on to its early oceans.

Well, atmospheric pressure is the weight of air as it pushes against you.

大气压力，即空气对你施加的压力，其本质就是空气的重量。

But the atmospheric pressure, while crushing by human standards, can't compare to the weight of even just a few kilometers of rock overhead deep in the Earth.

但是，大气压力虽然以类的标准来衡量是巨大的，但却无法与地球深处哪怕只有几公里的岩石重量相。

On a standard measure—predicting the altitude at which the atmospheric pressure is half as great as at sea level—it still trails the ECMWF model.

但在一项对某纬度大气压强是海平面一半的标准测试中，全球预报系统仍落后于欧洲中期天气预报中心.

The atmospheric pressure on Venus is 90 times greater than on Earth, because the weight of the atmosphere created by gases is heavier.

金星大气压地球上大90倍是因为金星浓厚的大气的巨大重量。

It happens when there's a rapid drop in atmospheric pressure that causes a storm to become very intense, very quickly. How intense?
