I can't understand the difference between a Wall cloud and a mothership, i am a weather enthusiast since 2024 I still can't tell the difference between these two cloud formations. I don't know if this is the right place to ask this, but I'd appreciate it if anyone can help.

Sometimes bugs form in the radar, in this case there's an inexistent circle of rain.
