“In an electrical storm, the storm clouds are charged like giant capacitors in the sky. The upper portion of the cloud is positive and the lower portion is negative. How the cloud acquires this charge is still not agreed upon within the scientific community, but the following description provides one plausible explanation.
In the process of the water cycle, moisture can accumulate in the atmosphere. This accumulation is what we see as a cloud. Interestingly, clouds can contain millions upon millions of water droplets and ice suspended in the air. As the process of evaporation and condensation continues, these droplets collide other moisture that is in the process of condensing as it rises. Also, the rising moisture may collide with ice or sleet that is in the process of falling to the earth or located in the lower portion of the cloud. The importance of these collisions is that electrons are knocked off of the rising moisture, thus creating a charge separation.”
Its all starting to make a lot more sense,
There is also a video that the Met Office produced to explain Lightning –
This is as you can see quite a dull video and doesn’t really visually represent how it works instead just shows several shots of lightning and a voice over explaining it. I realise i will still need a voice over explanation however i intend to create a much more visually educational video showing cold and warm winds and the charges within the clouds and how they react to other clouds and and also the earth.
I am also conducting a survey courtesy of survey monkey to try and find out more about what the general public think about met office and there educational video element. I am assuming that most will not have visited this site other than maybe to see the forecast. Therefore by using other forms of social media like Facebook and twitter to publicise the video this should help to gain traction for the main learning portion of the site.
The next step for me is really looking into how long this video needs to be for all the relevant information to be shown, but without it dragging on and becoming dull, as stated in the target audience portion the Met office
“We also recognise that snackable, short-form content is increasingly being viewed on mobiles using numerous social channels.”
This means i will have to try hard to try and produce something short but sweet, as it is clear attention spans are weakening in this digital age,
“The results showed the average human attention span has fallen from 12 seconds in 2000, or around the time the mobile revolution began, to eight seconds.”
However this could be due to brains being “better at identifying what they want/don’t want to engage with and need less to process and commit things to memory.”
In any case these short snappy videos are all over social media so to create something of that calibre would be wise. It also needs to connect with as many different social media groups as possible, therefore different dimensions and proportions need to be looked at for different sites.
