Maitai, Thank you for the explanations/definitions, very helpful. Here are some thoughts on the word definitions for you to consider:
= (noun) estimation, estimation, évaluation, estime, opinion, judgement, considération, estimate
"In qtVLM "tendency at esteem" compares the last grib data at the boat position with the one at the end of the esteem and tells you if the wind
is going to be stronger/lower easing/hauling." (=easing/increasing?)
Maybe the English translation for "Forcissant/Mollissant"
increasing/decreasing? (Mollisant is "easing off") (Croissant is increasing)
and "Adonner/Refuser" is not quite perfect...
adonner = (verb) engage
refuser = (verb ) refuse, decline, turn down, deny
= (noun) loch, loch, log
I think we would call it a Log or Logbook.
..The distance made for that last period of time ... in miles
enregistrer - verb register, record
, log, check in, tape, write down.
registre - noun record
, log, book, logbook, blotter
We also use terms for wind "Backing" and "Veering"?
(This may be off-subject.)
Backing wind NOAA's National Weather Service - Glossary
Backing Winds - Winds which shift in a counterclockwise direction with time at a given location (e.g. from southerly to southeasterly), or change direction in a counterclockwise sense with height (e.g. westerly at the surface but becoming more southerly aloft). The opposite of veering winds.
In storm spotting, a backing wind usually refers to the turning of a south or southwest surface wind with time to a more east or southeasterly direction. Backing of the surface wind can increase the potential for tornado development by increasing the directional shear at low levels.
Veering wind NOAA's National Weather Service - Glossary
Veering - A clockwise shift in wind direction (for example, south winds shifting to the west).

Chris- Those definitions are a little misleading in the context of severe weather
forecasting. Veering and backing can be used in a couple different ways:
1) Change in wind direction with time- If someone says that the sfc winds are veering, that would mean the surface winds are turning more southwesterly with time. If the surface winds are backing, that would mean they're turning more southeasterly with time, which would be more conducive to tornadoes. This is how veering and backing are typically used in severe-wx forecasting.
2) Change in wind direction with height- a veering wind profile (or turning with height) is conducive to thunderstorm rotation. Example- southerly winds at the surface, southwesterly winds at 700mb and westerly winds at 500mb.

Are backing and veering the same in both Hemisphere's ? I don't think so.
