Lightning rods have been around since Benjamin Franklin first discovered lightning was made of electricity. And by watching a thunderstorm, logic would conclude that if one were to position a metal rod at the highest point on a structure, a lightning bolt would strike it, direct the electricity into the ground, thus averting damage to the structure itself. Unfortunately, it’s not that simple. As strange as this may sound, metal doesn’t attract lightning. Nothing does. Lightning can strike anything, conductive or non-conductive, and what it does strike isn’t always obvious….

The recent outbreak of large and destructive tornadoes in the mid-west has a lot of folks speculating that perhaps global warming or climate change is the cause, but caution must be taken before making such correlations. Although the average number of tornadoes reported each year has in fact increased, this does not mean there are any more tornadoes now than in years past. That may sound contradictory, but a lot has changed in recent years that allows meteorologists to better detect and categorize tornadoes. In the last few years, there…

Have you ever seen little balls of snow that look like Styrofoam falling from the sky and wondered what they were? They look like hail, but they’re soft. They feel like snow, but they’re round. What exactly is this stuff? It’s called graupel, also referred to as snow pellets, soft hail, small hail, tapioca snow, rimed snow, and ice balls. Simply touching the graupel can cause it to quickly melt, unlike hail which is more durable, heavy and solid. In fact, if you pinch graupel, you can compress it quite…

With all the trillions of snowflakes that are piled up in your driveway, coating the mountain tops, and plowed from the road, it’s probably true that no two snowflakes are alike. Proving this would be quite a feat, for obvious reasons, but you’ll as you read below, you’ll see why the old adage it probably true. Snowflakes are very sensitive to micro-environmental variables such as wind, temperature, humidity, air pressure, cloud condensing nuclei, and air particles. Add an element of chaos theory to the mix and you’ll see below that…
