What are the basic fundamentals of fire safe building design?
I'm just going to answer one of your questions. Lightning strikes in both directions from the cloud to the ground and ground to cloud. What you do not see is the leader, also called a stepped leader. This establishes the path of the lightning. The pulse instantaneously follows this leader and it can go in both directions. Also what you do not see, well actually you can see this are lightning flicker, is that a lightening strike may have up to 10 pulses up or down the path, it happens too fast.
Lightning is gentle, thunder is sound. gentle travels speedier than sound. So if u listen thunder and be conscious lightning mutually, the thunder is likely from the most suitable bolt of lightning, and the hot bolt has happened and u see it.
Lighting is first. Always. Lightning is what we call the sight of a difference in static(or something else) charge. Lightning occurs when the net charge in one area, say the ground, is negative, and the net charge in a relitivlely nearby area, a cloud above, is positive. when the difference between charges is great enough the electrons from the negative charged area will jump to the positve area creating an electric arc. The two areas with different chrages can be anything, souch as your finger and a metal object. Lightning is jsut like any static discharge, but is only applied to the atmosphere. So lighting can come from the ground up, or the cloud down, or from cloud to to cloud. Lighting makes noise when it passes through the atmosphere because it forces the air in it's path out of the way, much like when you clap yours hands.
it rather is an enhance in man made atmospheric albedo (the mirrored photograph of sunlight) it rather is an extraordinary side consequence of pollutants that extremely counteracts international warming via reflecting or dispersing most of the sunlight before it could attain the earth's floor and radiate as warmth. After the 9/11 WTC attack in manhattan all jet liners have been grounded for 3 days, giving scientists of undertaking to learn man made atmospheric albedo brought about via vapor trails via measuring how plenty is brought about via 0 planes and via the slowly increasing form of jets after the no-fly restrict. Jets are actually not the only contributor to international dimming nonetheless. many forms of debris are in touch.
Dear Rebecca M : It seems to Me that everyone else here have posted very cientifica data, outstanding I am personally looking for lightning rods and other surge supression devices in a DIY mode, since thunderstorms are hitting My area lately and My house has no protection installed I know a fun fact : Odds are twice as much that You're struck twice by a lightning that to be killed by a serial killer Smile, Cute One ! ;-)
