no metar will show you Cirrus Clouds,

 

And yes, of course cirrus clouds are NOT specified in METARs.

 

Actually... to be a bit of a nit-picker here... They can be...tho this primarily for folks like Alex (who is learning to fly):

 

In the remarks section, you might see "significant cloud types" e.g. ACC with a direction (altocumulus castellanus) CCSL (cirrocumulus standing lenticular) or possibly cloud types - specified in this format 8/C_LC_MC_H... low / medium / high with the "C" being a numerical code for the cloud type for that "level" or "region".

 

An example: MMMX 260946Z 01004KT 12SM SCT200 10/06 A3029 NOSIG RMK 8/002

 

So in this case... the "0"s represents no clouds in the Low (stratus / cumulus types) or Medium (alto-) "region". The "2" represents Cirrostratus. The "8/" prefix indicating clouds can be remembered by thinking of sky condition coverage as it is based on eighths (FEW = 1/8 - 2/8 SCT = 3/8 - 4/8 etc.)

 

So yeah... they can be specified... but this should be mainly of interest to pilots / those preparing to take an exam for a license... or a wx nerd like me.

Didin't know that! Very interesting indeed, now I know what all those numbers in RMKs are.

 

But in Brazil, where I fly and all my books are based, we have chosen to have RMKs only for Wind Shear and Recent Events (RE).
