理解降水概率

老王

今天天气预报说降水概率是80%，看来要下雨了。

jīntiān tiānqì yùbào shuō jiàngshuǐ gǎilǜ shì 80%, kàn lái yào xià yǔ le.

Today's weather forecast says there's an 80% chance of precipitation, looks like it's going to rain.

小李

是啊，80%的概率挺高的，最好带伞。

shì a, 80% de gǎilǜ tǐng gāo de, zuì hǎo dài sǎn.

Yeah, 80% is pretty high, you'd better bring an umbrella.

老王

嗯，保险起见还是带把伞吧，万一真的下大雨呢？

ēn, bǎoxiǎn qǐjiàn háishì dài bǎ sǎn ba, wàn yī zhēn de xià dà yǔ ne?

Mm, it's better to be safe than sorry, let's bring an umbrella, just in case it really pours.

小李

对，这概率看着高，咱可别大意。

duì, zhè gǎilǜ kànzhe gāo, zán kě bié dàyì.

Right, with such a high probability, let's not take any chances.

老王

对了，这降水概率是怎么算出来的呢？

duì le, zhè jiàngshuǐ gǎilǜ shì zěnme suàn chū lái de ne?

By the way, how is this precipitation probability calculated?

小李

我听说用各种气象数据模型计算的，挺复杂的。

wǒ tīng shuō yòng gè zhǒng qìxiàng shùjù móxíng jìsuàn de, tǐng fùzá de.

I heard it's calculated using various meteorological data models, it's quite complex.
