Clouds 101: Cirrus Vertebratus

Today I have something fishy on our beloved skies for you. Fish in the sky you ask? Yup! Well, at least fish ribs…No I'm not crazy, just read further 🙂


Danas imam nesto sumnjivo na nebu za vas. Moguce su ribe na nebu. Ribe kazete u cudu? Da! Pa barem riblji skelet…Ne nisam poblesavila, samo citajte dalje.

Genera: Cirrus – 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.


Rod: Cirrus- odvojeni oblaci u obliku bijelih , delikatnih pramenova ili bijelih (barem vecinom bijelih) krpi ili uskih traka. Ovi oblaci imaju vlaknast (poput kose) izgled ili svilenkasti sjaj ili oboje.

Varieties: Vertebratus – the elements of which are arranged in a manner suggestive of vertebrae, ribs or a fish skeleton. This variety exclusively applies to Cirrus clouds.The occurence of these clouds seems to be connected to the location of jet streams.

Vrsta: Vertebratus – elementi koji su poslozeni na nacin koji podsjeca na vertebrae sto su ustvari rebra ili skelet ribe. Ova vrsta ekskluzivno pripada rodu cirusnih oblaka. Pojava ovih oblaka se povezuje sa lokacijom mlaznih struja.

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
