Clouds 101: Cirrocumulus floccus (Ci flo)

Genera: Cirrocumulus – Thin, white patch, sheet or layer of cloud without shading, composed of very small elements in the form of grains, ripples, etc., merged or separate and more or less regularly arranged; most of the elements have an apparent width of less than one degree. Cirrocumulus is composed, almost exclusively, of ice crystals; strongly supercooled water droplets may be present but are usually rapidly replaced by ice crystals. Cirrocumulus may form in clear air. Cirrocumulus may also result from the transformation of Cirrus or Cirrostratus, or from a decrease in size of the elements of a patch, sheet or layer of Altocumulus. Cirrocumulus clouds are always transparent enough to reveal the position of the sun or the moon.

Rod: Cirrocumulus – Tanko, bijelo parce, veo ili sloj oblaka bez sjena koji se sastoji od veoma sitnih elemenata u obliku zrna, talasa, itd., koji su ili spojeni zajedno ili su odvojeni te manje-vise uredno rasporedjeni. Pri tome, vecina sastavnih elemenata je medjusobno odaljena na manje od jednog stepena. Cirrocumulus se sastoji, skoro bez izuzetaka, od ledenih kristala. Snazno prehladjene kapljice vode mogu biti prisutne u sastavu ali su obicno velikom brzinom zamijenjene ledenim kristalima. Cirrocumulus se moze formirati u cistom zraku. Cirrocumulus takodjer moze nastati kao rezultat transformisanja Cirrusa ili Cirrostratusa. Isto tako moze nastati umanjenjem velicine sastavnih elemenata krpe, vela ili sloja Altocumulusa. Cirrocumulusni oblaci su uvijek dovoljno prozracni da se kroz njih moze vidjeti pozicija sunca ili mjeseca na nebu.

Species: Floccus – from the Latin floccus, which means tuft of wool, fluff or nap of a cloth. The elements of Cirrocumulus may consist of very small tufts with ragged lower parts.

Vrsta: Floccus- od latinske rijeci floccus, sto znaci cuperak ili pramen vune, paperje ili komad tkanine. Sastavni elementi Cirrocumulusa se mogu sastojati od jako malih pramenova koji su u donjem dijelu iscjepkani.

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

    I love them too :)) Cloud lovers, we understand each other 😉

    Thank you and Merry Christmas to you! <3
