21 Reasons to Watch the 2010-2011 NBA Season
As we enter mid-spring and the weather finally begins to warm up a bit, we expect to see quite a few thunderstorms in Oregon. Inspiring awe in some while scaring the pants off others (but not ME, I'm definitely not scared of lightning. No sir,) it is no surprise that cultures all over the world associate lightning with deity. But what exactly is it?
During an electrical storm, the upper portion of the storm clouds has a positive charge and the lower portion has a negative charge. It is not quite clear how the clouds attain these charges in the first place, but one theory is that different forms of liquid (vapor, water and ice droplets) collide as they rise and fall within a cloud. In the collision, electrons are knocked off of the rising moisture and they gather at the bottom of the cloud, creating the negative charge. It is thought that rising moisture then carries a positive charge to the top of the cloud. The charge separation within the cloud is what creates an electric field, the strength of which is related to the amount of charge buildup in the cloud.
When the electric charge inside the cloud becomes very strong, the air becomes ionized (the positive ions and electrons are spaced further apart than before and the electrons can move more freely.) Insta Thunder Apk The strong ionization causes the air to begin to break down, allowing for currents to flow in an attempt to neutralize the charge. These currents are called leaders, and they provide a path through the cloud for the lightning to follow. The initial (or stepped) leader does not move smoothly, but jumps in a jagged fashion. Many leaders form at the same time, but the first one to make contact with the ground is the one that gets the lightning.
The entire process is a bit more complicated, but there you have the basics of how lightning is formed. Lightning is much too powerful for even the best of surge protectors to protect against, and it can reach temperatures of 54,000 °F. (For comparison- the surface of the sun is only about 9,900 °F.) An average bolt of lightning carries about 30,000 amps. A single ampere of current is all it takes to kill a human!
Lightning is a complex phenomenon with many variations and exceptions. Sometimes it shows up in the most unexpected of places.
