Jet stream

[Roundway]

I am currently researching a non-technical history of what is now known as the 'jet stream'. Please bear with me.

The term itself first appeared in 1947 in a collaborative paper written by meteorologists, led by Carl-Gustaf Rossby, at Chicago University. However, in 1939 a German meteorologist, Dr Heinrich Seilkopf, had published a book which included a description of what is now known as the jet stream, but he called it Strahlströmung. Today the word translates in English as 'jet flow' but what I would like to determine is would there have been an alternative translation in 1939?

I am reasonably confident that Rossby would have been familiar with Seilkopf's work and possibly followed his lead.

A bit off the beaten track, but I would appreciate any advice.
