What is the fire of St. Elmo?

st. Elmo's fire is a weather phenomenon that attracted attention and comment for hundreds of years. This phenomenon is reflected in electrical storms and other weather conditions that create atmospheric electric fields. If the conditions are correct, there may be shining blue to green around things such as lightning, pipes and masts of the ship. While the fire of St. Elmo looks like a fire, in fact it is a plasma, a gas that was ionized because of the presence of an extremely large electric field. As soon as the charge is scattered, the light disappears after a few seconds or minutes.

Many people really saw the fire of St. Elma, but maybe they didn't realize it. Neon lights are a carefully closed and controlled form caused by the transformation of gas into plasma. Neon lights come in a variety of colors, depending on the gases closed in tubes; A mixture of gases in the Earth's atmosphere is what causes a natural phenomenon to appear green on blue.

This interesting weather event is calledIt was overshadowed for the patron saint of the sailors, the Saints of Erasmas formmae, also known as St. Elmo. The sailors often witnessed the fire of St. Elma on their travels and superstitions came to a mysterious shining plasma; Many sailors felt that his presence was a sign that Holy took care of them. St. Elmo can also appear on the ground and tend to concentrate around pointed objects that concentrate electric charges.

For this phenomenon, the grounded object must be discharged electricity in a charged atmospheric field. Electric from the grounded object ionizes the surrounding air, pulls the molecules into the air apart and creates what is called corona discharge, an extended electrical spark that causes a moment a clear flash. Storms are ideal for creating a fire. Elmo, because they tend to generate feespronies, create the circumstances necessary for release from corona.

If a person is close enough to the fire. Elmo, sometimes he hears buzzing or hissing. Because the corona discharge simply shining plasma, rather than a real fire, does not cause the objects around it, and sometimes the light can be adequate to the tricks. For example, airlines pilots wrote about playing with the fact that they gather outside their windows and introduce their fingers through the windshield to attract plasma.
