"Thunniform" Natural Recordings by Native Speakers
Thunniform refers to the eel-like body shape of certain marine animals, such as the swordfish and the oarfish. The term specifically describes a type of body form that is long and slender, with a cylindrical or tapering body shape that is characteristic of these species. It is often used in zoology and biology to describe the morphology of these fish.
A thunderstorm is a precipitation system characterized by sudden changes in the atmosphere. It occurs when a mass of warm, moist air collides with a mass of cooler, drier air, resulting in the rapid formation of cumulonimbus clouds. These clouds can grow tall enough to reach the stratosphere, and in doing so, can carry a large amount of electrical charge.<br><br>As the storm system develops, updrafts of warm air can carry the water droplets in the cloud upward, where they freeze into small ice crystals. The ice crystals collide with each other and the water droplets, causing the electrical charges to become separated within the cloud. The resulting discharge of electrical energy is what we know as lightning.<br><br>Thunder is produced when the rapid expansion of hot air along the path of a lightning bolt creates a shockwave that travels through the air as a pressure wave. The sound we hear as thunder is the pressure wave as it reaches our ears.
