Since this is not the case, average lightning temperatures have been calculated. It is shown that the procedure of calculating lightning temperature by assuming the stroke temperature to be constant yields a temperature which is lower than, but within 10 per cent of, the actual peak lightning ...
Lightning is basically an electric current (yes, like those we have in our houses, except lightning is thousands of time more powerful and dangerous). The temperature of lightning is around 27,000 degrees Celsius, which is nearly 5 times hotter than the surface of the Sun! (Source...
According to this theory, lightning causes thunder sound. The streams of lightning are very hot, much hotter than the surface of the sun. When the high temperature lightening stream hits the surrounding air, sudden rise in temperature takes place. It brings along an instant expansion of heated ...

Lightning can be very dangerous. Every year, lightning kills people because it can start big fires or because it reaches a temperature of 28,000℃. About 1,000 people are hit by lightning every year in the United States, and about 100 of them die as a result. Lightn...
In the AZ31 magnesium base compound materials high temperature compression deformation process organization evolves the rule and the distortion temperature, the strain speed as well as should the variable close correlation.Moreover this kind of organization evolves receives the distortion temperatur[translate...
Carrier’s partial solution involved circulating cold water and then balancing their temperature with the rate of air flow. It was at the Pittsburgh Railroad Station that the solution came to him. Few other inventors have had such an impact on modern life and yet remained so little-known. Air...

There are other types of lightning,such as ball lightning (), positive lightning, and ground-to-cloud lightning(云对 的电). In less than a second, lightning can reach a temperature of 28,000C, which is hotter than the sun.In Americ a. about 100 people are killed by lightning each ...
Wind turbines on the coast of the Sea of Japan have been damaged by lightning in winter. This is due to the frequent occurrence of upward lightning from wind turbines in winter. Occurrence of upward lightning proves to be closely related to the temperature distribution at high altitudes. In th...
