Clouds 101: Cumulus humilis (Cu hum)

8/26/2012


Today on the repertoir we have a cute cloud. I call him the popcorn cloud :) I will also post as much of my own pictures of clouds as I can.

Danas na repertoaru imamo jedan jako sladak oblacic. Zovem ga kokica :) Takodjer cu da se potrudim ukljuciti sto vise slika oblaka koje sama napravim.

Genera: Cumulus - detached clouds, generally dense and with sharp outlines, developing vertically in the form of rising mounds, domes or towers, of which the bulging upper part often resembles cauliflower. The sunlit parts of these clouds are mostly brilliant white; their base is relatively dark and nearly horizontal. 

Rod: Cumulus - zaseban tip oblaka, uopsteno je gust sa ostrim obrisima, razvija se vertikalno u obliku rastucih nasipa, kupola ili tornjeva, ciji je rastuci gornji dio cesto slican karfiolu. Da, povrcu. Suncem osvijetljeni dijelovi ovih oblaka su cesto zaslijepljujuce bijele boje, baza im je relativno tamna i skoro pa horizontalna. 

Species: Humilis - cumulus clouds of only a slight vertical extent; they generally appear flattened.

Vrsta: Humilis - kumulusni oblaci jako blagog vertikalnog razvoja i cesto izgledaju spljosteno. 


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
