Readings of 漏斗：じょうご vs ろうと


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?




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.
