Upwelling air cools and forms white ammonia clouds; that creates the light colored zones.

上升流气冷却，形成白色氨云；这样就形成了浅色区域。

Rising air cools, causing any water vapor within it to condense and form rain or snow.

升高气温度降低，使其内部水蒸气冷凝并形成降雨或降雪。

So that marine influence that brings cool moist air from the ocean is now keeping the fire relatively mild.

The water vapor rises with the hot air. But the air cools with time.

水蒸气随热气上升。但是气会随时间冷却。

Then, that air cools, and water inside can condense to can form clouds -- which means more rain.

Never wind them in the early morning before a room has warmed up, nor too late, when the night air cools them down.

In the United States, strong temperature differences tend to develop between hot, humid air in the south and cooler, drier air to the north.

在美国，南方炎热潮湿气和北方较冷干燥气之间往往会形成较大温差。

Without ocean currents circulating warm and cool air across the planet, you'd have a lot more extreme differences in temperature and climate.

如果没有洋流在地球上循环温暖和寒冷气，你温度和气候就会有多极端差异。

A clever upgrade of a humble but useful technology Every night, air cooled and moistened by the Humboldt current blows over Chile's northern coast and across the Atacama desert.

一种不起眼但有用技术聪明升级每天晚上，洪堡洋流吹过智利北部海岸和阿塔卡马沙漠，使气变得爽、湿润。

The liquid is cooler than the ambient air, so the heat from the warm air transfers into the liquid, and then a fan blows the cooled air back into your room.

液体比环境气冷，因此热气中热量转移到液体中，然后风扇将冷却后气吹回房间。

Only when the air cools down past a certain point — called the dew point — does this breaking-apart slow down enough for little clusters of water molecules to grow into droplets.

只有在气冷却到特定温度——即霜点温度——才能令断键过程减缓到可以让一小撮水分子凝结成水滴。

Standing like a lonely sentinel on Titano’s farthest peak, is Montale, the smallest of the towers. Although the tower itself is now closed, its remoteness means you’ll enjoy the mountain’s cool air without the crowds.
