Drawing Challenge #8 Clouds X Science Pic / 繪圖挑戰 #8 云朵 X Science Pic

又一期參加 @helene 的 #drawingchallenge post, 再接再勵, 繼續和科學混一下, 當然#sciencepic 一下

Another session for @helene 's #drawingchallenge post, another fusion post with science, and of course #sciencepic!!

本屆大會的主題是：雲（我想在最終幻想中畫一個，但是我的畫畫技能T-T）
This session's theme is: Cloud (I so wanted to draw that one in Final Fantasy, but I lacks the skills T-T)

這句每次也要講明一下
再次説明我不擅長畫畫, 請見諒XD
Once again I must state, I am not good at drawing XD

先貼完成品：
First post the final product:

和之前一樣我用ipad mini，與 bamboo手寫筆，和應用程序 sketches
Same as always I am using my ipad mini, Bamboo stylus fineline, and the application Sketches

步驟:

在晴朗的日子裏的雲是很好看，但沒有太多我想談的科學，所以我們還是讓比卡超在天空中跳舞吧〜
Ordinary clouds in a fine day is pleasant to look at but not much interesting science i would like to talk about so, let's let pikachu dance in the sky~

上色

來點科學
Here is the science bits

有雷電的雲通常是由積雨雲產生，電排放過程是一個非常複雜的過程，但基本上是由電氣化造成的。這種電氣化是在冰晶和霰碰撞時產生的，在該過程中，冰晶變成帶正電的霰變成帶負電的。(因為冰晶向雲中升起來，霰沉澱下來，這能說明為什麼通常在雷暴之前，我們看到那些很長很高大的雲 - 積雨雲。) 雲在頂部變成帶正電，雲的底部變成帶負電的。
The clouds that bring lightning and thunders are generally bring upon by the Cumulonimbus, and the discharge process is a very complicated process, but basically a result of the discharge of the charge build up from the thunderstorm electrification. This electrification is bought upon the collision of the ice crystal and the graupel, during the process, the ice crystal become positively charged while the graupel becomes the negatively charged. (Because the ice crystal rise up, and the graupel precipitate down, this can partially signify why usually before we got caught in the thunderstorm, we see those big column cloud -- Cumulonimbus.) The cloud becomes positively charged on the upper part and the lower part of the clouds become negatively charged.

當雲內的電荷積累超過空氣的絕緣能力時，會發生放電，這可能發生在雲內，雲與雲之間或我們較常見看到的雲到地閃電通電，我們看到的閃光其實是一種電荷或電子的流動，實際上是等離子體的流動！大地之母在表現自己的力量本性。
When the charge build up within the cloud exceed the insulation ability of air the discharge will occur, this can occur within the cloud, between two clouds or the more common ones that we see, the ones that channel the charge from clouds to ground lightning, creating the flash we see. This flow of charge, or electrons is actually a flow of plasma!! Witness mother nature when she is showing her power.

雷暴期間總是有衝動飛無人機，任何人想以科學的名義捐獻一個給我試試看？
I always got the urge to fly a drone during thunderstorms, anyone want to donate one in the name of science??

有人想過，如果他們在公海和雷暴中，鹽水導電，為什麼他們不被觸電，我年輕的時候常常被這問題打擾我，直到我認識物理 XD
Anyone ever wonder, if they were in open sea and thunderstorm hits, and salt water conduct electricity, why they don't get electrocuted, always bothers me when I was young, until I know physics XD
