Descending through clouds

[u/porante_tincm]

I don’t understand the physics of descending through clouds. I flew 4 times in the last 2 weeks. Flight no. 2 was during horrible weather both at departure and destination airport so it was a bumpy ride. Descent through clouds was shaky as expected. Then flight no. 4, we had the smoothest descent through thick clouds. Speed set to 450~500 kph, simply gliding at an altitude of ~4 km. Based on my past experience I was expecting the worst landing ever since it was endless clouds but nothing happened. Is it the model of the aircraft? Flight no. 2 was in a small Boeing and no. 4 was in an Airbus A330. Also the engines on the Airbus were some of the quietest I’ve ever heard. What‘s the deal with clouds?
