The jumps can also be from delays in the supply chain. If you do not have enough storage buildings, then your extractors might sometimes struggle to get rid of raw materials, which means they shut down production for a while. Same goes for processors that run out of raw materials. And processors might even import raw materials, because there are no available trucks to deliver anything to them.

In general you want at least one storage building of a type to be set to balanced and never be full and always have a handful of trucks available whenever you check it. Ideally have a couple of storage buildings like that in your city.

This guide goes into a lot more detail about storages and how important they are for a smooth production chain.
