Weather abbrevation question

[Tarmo Tanilsoo]

I was reading latest satrep and I noticed there abbrevation THR cloud.

I am wondering what does THR cloud mean?

Hi Tarmo,

THR stands for Thickness Ridge Cloud in the SATREP.
Some of my collegues at KNMI (Royal Dutch Meteorological Institute) are making this kind of satellite-tool a few times a day.

In the satrep-manual you can find more information. It can be found here:

http://www.zamg.ac.at/docu/Manual/SatManu/main.htm

It says for example:
THICKNESS RIDGE CLOUDINESS
Organised cloudiness in the thickness ridge in front of Cold Fronts which can be extremely convective in unstable situations.
