Clouds 101: Cirrus fibratus (Ci fib)

Starting from today, I will publish a post about one of the cloud types every week. The post will include some basic information and description of a cloud, followed by an illustration and at the bottom of every “Clouds 101” post you can find some general information about clouds that will, hopefully clarify certain expressions and names. I hope you enjoy!

Cirrus fibratus (Ci fib) 

Genera: Cirrus clouds are detached clouds in the form of white, delicate filaments or white or mostly white patches of narrow bands. These clouds have a fibrous (hair-like) appearance, or a silky sheen, or both.

Species: Fibratus – detached clouds or a thin cloud veil, consisting of nearly straight or more or less irregularly curved filaments which do not terminate in hooks or tufts.

Pocevsi od danas objavljivati cu clanak o odabranoj vrsti oblaka jednom sedmicno. Clanak ce da obuhvata neke osnvovne informacije i opis vrste oblaka, popraceno slikama i na dnu svakoj “Clouds101” clanka moci cete pronaci osnovne cinjenice o oblacima(podjele i definicije) koje ce, nadam se, pojasniti vam neke nazive i izraze. Nadam se da cete uzivati! 


Cirrusi su pojedinacni oblaci u obliku bijelih njeznih pramenova bijelih ili barem vecinom bijelih krpi i uskih traka na nebu. Ovi oblaci imaju vlaknast (poput pramena kose) izgled ili svilenkasti sjaj, tj. oboje. Fibratus je pojedinacan oblak tankog vela od skoro pravilnih ili manje-vise nepravilno zakrivljenih niti koje ne zavrsavaju u obliku kukica.

Definition of a cloud: 

A cloud is a visible aggregate of minute particles of water or ice, or of both, in the free air. This aggregate may include larger particles of water or ice and particles, such as those present in fumes, smoke or dust.

Definicija oblaka: Oblak je vidljivo agregatno stanje zasicenih cestica vode, leda ili vode i leda, koje se nalaze slobodne u zraku. Mogu biti u pitanju i krupnije cestice vode i leda i cestice poput onih koje su prisutne u dimu, isparenjima ili prasini. 

Appearance of clouds:

The appearance of a cloud is determined by the nature, sizes, number and distribution in space of its constituent particles. Appearance is best described in terms of dimensions, shape, structure, texture, luminance and colour of the cloud.

Pojava oblaka tj. njihov izgled je odredjen karakterom, velicinama, kolicinom i raspodjelom cestica koje ga sacinjavaju kroz prostor. Izgled oblaka je najbolje opisan u kroz dimenzije, oblik, strukturu, teksturu, osvjetljenost i boju oblaka. 

Classification of clouds:

A classification of the charcteristic forms of clouds, in terms of “genera”, “species” and “varieties” has been established by the WMO(World Meteorological Organisation).

Klasifikacija karakteristicnih oblika oblaka u smislu “rodova”, “vrsta” i “podvrsta” je ostvarena od strane WMO (World Meteorological Organisation) tj. Svjetske Meteoroloske Organizacije.

(I) Genera 

The classification is essentially based on 10 main groups, called genera, which are mutually exclusive, that is to say, a given cloud can belong to one genus only. The genera are;

Podjela na rodove je ustvari podjela na 10 osnovnih grupa zvanih rodovi koji su medjusobno posebni, sto znaci da odredjeni oblak moze da pripada samo jednom rodu. Podjela na rodove je slijedeca: 

Cirrus – Ci 

Cirrocumulus – Cc 

Cirrostratus – Cs 

Altocumulus -Ac 

Altostratus -As 

Nimbostratus -Ns 

Stratocumulus – Sc 

Stratus – St 

Cumulus – Cu 

Cumulonimbus – Cb 

(II) Species

Obseved peculiarities in the shape of clouds and differences in their internal structure have led to the subdivision of most of the cloud genera into species.

Osmotrene pojedinosti u obliku oblaka i njihovih razlika u unutarnjoj strukturi su doveli do podjele vecine rodova oblaka na vrste.

(III) Varieties

Clouds may exhibit special characteristics which determine their variety. These characteristics are related to the different arrangements of the could elements.

Oblaci mogu iskazati posebne karakteristike koje ce da odrede njihove podvrste. Te karakteristike su u vezi sa razlicitim rasporedom elementa oblaka.

(IV) Supplementary cloud features 

Dopunske odlike i oblaci pratioci:

1. incus – inc

2. mamma – mam

3. virga – vir

4. praecipitatio – pra

5. arcus – arc

6. tuba – tub

7. pileus – pil

8. velum – vel

9. pannus – pan

    Oh,than this is a place for you:)) I am extremely glad someone is also obsessed with clouds!
    I will be posting more of these, one each week so feel free to stop by from time to time 🙂

    Thanks for following, I do appreciate it! :*
