Is there any difference in meaning between the words じょうご and ろうと, both
meaning something like "funnel", both written with the kanji 漏斗?

There's some indication in the answers
[here](http://oshiete.goo.ne.jp/qa/40533.html) that ろうと may be a specific term
used when you're talking about scientific experiments, but no such distinction
in the dictionaries I have access to.

How about in compounds? For example, 漏斗雲{ろうとうん} - is it always ろうと in these
cases?

Readings of 漏斗：じょうご vs ろうと
In typical everyday usage, the two words are fundamentally the same. However,
distinctions can be made between them.

  * zyougo: from 上戸 (a person who enjoys liquor), it expresses how liquids are sucked in without spilling like a funnel. The meaning is more abstract and includes funnel-like objects as well.

  * routo: (non-abstract) specifically a funnel; this is the preferred terminology in science experiments.

> How about in compounds?

I would expect it to be routo-. From the above explanation, zyougo is merely
atezi for 上戸, so this limits the likely hood of compounds with the same
reading. Also, compounds typically narrow a meaning to something more
specific, while zyougo is already an abstract noun compared to the more
specific routo.
