The air held the smoky aroma of the asado, a feast laid over open coals, the pride of an Argentinian gaucho.

空气中弥漫着 asado 的烟熏味，这是一场在露天煤炭上举行的盛宴，是阿根廷高乔人的骄傲。

Warm air holds water vapor better than cool air, so when warm air starts to cool, it can no longer hold as much of the vapor.

暖空气中的水蒸气比冷空气中的更多，所以当暖空气的温度降低时，就存不住那么多的水蒸气了。

The main reason is to do with the way in which hot and cold  air hold onto moisture, and how this is tied into the greater cycle of air movement in the Tropics.

主要原因与热空气和冷空气保持水分的方式有关，以及这与热带地区空气运动的大循环有何联系。
