Does cloudy weather in Beijing have much to do with humidity?

In Beijing, especially in summer, cloudy days do have a certain relationship with humidity, not causality, but correlation, that is to say, the air humidity is relatively high on cloudy days in general.

It will be cloudy for four or five days before July 2 1. Just before it began to rain around 9 am, the maximum relative humidity of the air reached 85%. Our people said it was cloudy and stuffy, and there was no heavy rain.

But Beijing in winter is different. Although it is sometimes the perineum, the air is still very dry. Summer is usually cloudy, so the air humidity will be higher.
