What happens is that a certain amount of heat energy is required to convert liquid water into vapor.
具體過程是:一些數量的熱能被要求將液體的水轉化成蒸汽。
So when water evaporates from the ocean,
所以當水從海洋中蒸發時,
it takes energy to convert that water into a gaseous form, into water vapor.
它需要能量來將水轉化成氣體形式,轉化成水蒸汽。
But that heat energy, that conversion energy, doesn’t raise the temperature of the water vapor or the air,
但是那種熱能,那種轉化用的能量不會提高水蒸汽或空氣的溫度,
it’s just stored in the water vapor.
只是儲存在水蒸汽中。
Then later when the water vapor converts back to liquid water, that energy is released.
接著稍后當水蒸汽再度轉化成液體水時,那種能量就被釋放出來了。
So when water evaporates, energy is taken from the ocean, and it’s stored in the water vapor, in the air.
所以當水蒸發時,海洋中的能量就減少了,被儲存在了水蒸汽,即空氣中。
Then the air, the wind, transports the water vapor to some other part of Earth,
然后空氣,風把水蒸汽運到了地球上的某個其他地方,
then the water vapor converts back into liquid water.
接著水蒸汽便再度轉化成了液體的水。
It rains, in other words, and the heat energy that was stored in the water vapor is released into the new environment. Okay?
換句話說就是會下雨,而這種儲存在水蒸汽中的熱能就被釋放進了新環境中。對吧?
So the transfer of heat and the transfer of water are very closely related, and what’s the primary vehicle for this transfer?
所以熱能的轉移和水分的轉移是緊密相連的,這種轉移的主要工具是什么?
The wind! So wind is a very critical element in the redistribution of both the Sun’s energy and Earth’s water.
風!所以風在重新分配太陽能和地球上的水中起著至關重要的作用。
