![]() ![]() ![]() Continuing currents (that last for hundreds of milliseconds) which are long quasi-stationary arcs.The charges have three main modes in which they can be sent to the ground from the cloud (see diagram): The CGs can be categorized into 4 groups: (a) downward negative (90% of all CGs are of this group), (b) upward positive, (c) downward positive, and (d) upward negative. There are two main types of lightning discharges: cloud-to-ground (CG) and intra-cloud (IC), the latter accounting for about 3/4 of all discharges (there are however other types of discharges that are less commonly encountered such as ball lightning). The 4 groups of cloud-to-ground (CG) discharges (adapted from Lightning: Physics and Effects (2003)). ![]() 2.3.2 Effect of tortuosity on rumbling or clapping thunder.2.3.1 Assuming perfectly cylindrical/spherical expansion.The air molecules within ionize to generate a highly powerful shock wave that can be heard over distances up to 25 km, depending on the wind. the heating of a narrow channel to ~24000K. It was only in the late 1800s that the true physical causes were discovered by the scientific community i.e. Early explanations of this phenomenon included fights between Zeus and his subordinates in Greek mythology, or the collision of clouds in the sky by Aristotle. Thunder has intrigued and frightened humans for millennia. IP that drives the song throughout the storm and we haven’t looked at rain clouds the same way since.Thunder is defined as the sound signature associated to the shock wave produced after a lightning discharge. Our team brought the boogie to the adorable Nick Jr. The micro and macro worlds were all shot in house at our studio– using a tabletop setup for the papercraft clouds and our brand new, multiplane animation setup for a look inside them.Īs soon each shot was ready, we turned it over to our amazing 2D animators to begin character and FX animation. This approach still felt hand crafted, tying in well with the other scenes, but would give the kiddos a cue that we’re now at a different scale. Given that the majority of the sets were papercraft, what would be a good complimentary approach? After some creative brainstorming, we decided to illustrate what happens inside the clouds at a microscopic level, through poly-fill, plasticine, and plastic gem stones. We needed a way to differentiate the look of the macro and micro worlds. To properly explain Lightning & Thunder, we needed to not only show the flash of light and hear the crash of sound, but depict what’s going on inside the cloud to produce both. Working with the experts at Nick Jr, we devised a 2D FX animation that resembled the volume buttons on your computer to do just that. Sun of course! One of the design challenges was figuring out a unique way to visualize the sound of thunder for our young audience. The main character, the “Thundercloud”, remained the only one built practically and animated in camera–aside from a quick cameo by Mr. We chose papercraft environments, adding in our 2D animation hero characters in post. came to us for our skills in mixed media work. While this video could have easily been done in one, simple animation style, our pals at Nick Jr. The concept and song were inspired by the light show mother nature puts on during every thunderstorm– it’s truly a concert in the clouds. It has a fun concept, a super catchy song, and allowed for quite a bit of freedom in developing the story and techniques that ultimately brought it all together. In terms of work we love, it checked all the boxes. This project brought so much joy to our studio. But, shoot us an email and we can show you the whole thing. The entire piece is ONLY available on the recently redesigned Noggin App. The video above is very short cutdown from the full music video. We created this fun mixed media rap video for the updated Noggin app. Did you ever wonder about the thunder and the lightning? Well, the Nick Jr crew is here to show you what they’re all about.
