VPD turns out to, much like unchecked coronavirus, grow exponentially.

事实证明，VPD 就像未经检查的冠状病毒一样呈指数增长。

Climate scientists measure this trait using a statistic called the vapor-pressure deficit, or VPD.

气候科学家使用称为蒸气压不足或 VPD 的统计数据来衡量这一特征。

That's because the VPD in the new climate would be 53.7, which is larger than the old VPD of 50.

这是因为新气候下的 VPD 为 53. 7，大于旧的 VPD 50。

This is because VPD measures the absolute saturation of the atmosphere, which increases even if the atmosphere stays just as humid.

这是因为 VPD 测量的是大气的绝对饱和度， 即使大气保持潮湿， 饱和度也会增加。

Even if relative humidity stayed the same at 50 percent—that is, even if average humidity rose to 53.7 units of humidity—the VPD would still rise.

即使相对湿度保持在 50% 不变——也就是说， 即使平均湿度上升到 53. 7 个湿度单位——VPD 仍会上升。

But the onslaught of fires in recent years should teach us something about climate change and western wildfire, the researchers said: Thanks to VPD, every additional amount of warming leads to exponentially more fire than the year before it.

但研究人员表示， 近年来的火灾袭击应该让我们了解气候变化和西部野火：多亏了 VPD， 每增加一个变暖量就会导致比前一年成倍增加的火灾。
