How to evaluate the weather forecast that comes with Apple's mobile phone?

Quite accurate. Apple's weather forecast is different from that of the Canadian Meteorological Bureau in many cases.

Then I once thought that Apple's was more accurate.

Later, it turned out that this was not the case.

Apples are too chicken thieves.

Apple weather forecast criterion: report good news but not bad news.

Canadian Meteorological Agency: Take the average.

For example, there is a shower today, and the sun will shine after the shower.

Apple: A big dark cloud is raining.

Canadian Meteorological Agency: Draw a small cloud in the sun.

But if you look at the hourly forecast, the Canadian Meteorological Bureau will give a shower warning.

(Apple also has an hourly forecast, that is, the worst case is taken every hour, and the Canadian Meteorological Bureau takes the average every hour. )

As an ordinary user, most of us pay attention to the weather forecast in the hope of good weather, so psychologically speaking, predicting the worst-case apple is more suitable for us.

However, the weather forecast given by the government meteorological bureau is honest, so it is often scolded.

Recently, I watched Aurora in Huangdao Town and paid attention to the weather forecast for at least a week. The above results are based on my own actual observation that day.
