What Is a Tornado? A tornado is a violently rotating column of air that extends from a thunderstorm to the ground. It's one of the most powerful and destructive phenomena on Earth that can cause major damage. Tornadoes vary in size, shape and intensity, but they often take the shape of...
Fog often dissipates with daylight. This is sometimes referred to as the fog “burning off” but that analogy is not correct. When the sun rises, the air and ground warm up. This leads tothe air temperature being warmer than the dew point temperature, which causes the fog droplets to eva...
A super cell thunderstorm is a mature cumulonimbus cloud with internal rotation, called a mesocyclone. Air moving in different directions at different altitudes causes the super cell to rotate, which can cause tornadoes or severe winds. Super cells can be very stable systems, and dangerous weather...
In June 1756, Benjamin Franklin attached a silk string to a kite and launched it during a thunderstorm. He then attached the string to a key and tied it to a post. As the storm became stronger, the string became soaked with water and allowed electricity from the clouds to pass along the...
What causes a roll cloud? The roll cloud is not attached to its parent thunderstorm. It's associated with a gust front or outflow boundary out ahead of the thunderstorm. These clouds form whenwarm, moist air is lifted by rain-cooled air moving underneath it caused by the storm's downdraft...
The safest procedure, inconvenient though it may be, is to ensure that susceptible hardware is plugged into the suppressor box and to unplug the suppressor's main power cord when the equipment is not in use if you live in a thunderstorm-prone area. ...
a thunderstorm. They attached a key to the kite string, and the wet string conducted charge from the cloud to the key which gave off sparks when he touched it. (Contrary to some versions of the legend, the kite was not struck by lightning. If it had been, the results could have been...
I don't know how else to say it. It's that look that dogs get in their eyes when there's a thunderstorm coming and they're afraid. I have only read one mention of dogs and it was connected with the sound of thunder, only the lady said there wasn't any at that time -- just ...
