Explanation: Watch a huge lightning storm move across the eastern USA. The huge storm caused much damage and unfortunately some loss of life for people in its path. Seen from space, the lightning is seen as momentary flashes in the featured time-lapse video recorded last month by the Geostationary Lightning Mapper (GLM) aboard the GOES-16 satellite. The outline of North America is most evident during the day, while the bright lightning strikes are most evident at night. Inspection of the video shows that much of the lightning occurred at the leading edge of the huge tail of the swirling storm. Because lightning frequently precedes a storm's most violent impact, lightning data from GLM holds promise to help reduce the harm to humans from future storms.

Franklin was said to have noted that the prevailing winds were actually from the northeast, contrary to what he had expected. In correspondence with his brother, Franklin learned that the same storm had not reached Boston until after the eclipse, despite the fact that Boston is to the northeast of Philadelphia. He deduced that storms do not always travel in the direction of the prevailing wind, a concept that greatly influenced meteorology. [Forty years later] after the Icelandic volcanic eruption of Laki in 1783, and the subsequent harsh European winter of 1784, Franklin made observations connecting the causal nature of these two separate events. He wrote about them in a lecture series.>>
<<Benjamin Franklin (January 17, 1706 – April 17, 1790) started exploring the phenomenon of electricity in 1746 when he saw some of Archibald Spencer's lectures using static electricity for illustrations. Franklin proposed that "vitreous" and "resinous" electricity were not different types of "electrical fluid" (as electricity was called then), but the same "fluid" under different pressures. He was the first to label them as positive and negative respectively, and he was the first to discover the principle of conservation of charge. In 1748 he constructed a multiple plate capacitor, that he called an "electrical battery" (not to be confused with Volta's pile) by placing eleven panes of glass sandwiched between lead plates, suspended with silk cords and connected by wires.
In 1750, he published a proposal for an experiment to prove that lightning is electricity by flying a kite in a storm that appeared capable of becoming a lightning storm. On May 10, 1752, Thomas-François Dalibard of France conducted Franklin's experiment using a 40-foot-tall iron rod instead of a kite, and he extracted electrical sparks from a cloud. On June 15 Franklin may possibly have conducted his well-known kite experiment in Philadelphia, successfully extracting sparks from a cloud. Franklin's experiment was not written up with credit until Joseph Priestley's 1767 History and Present Status of Electricity. Franklin was careful to stand on an insulator, keeping dry under a roof to avoid the danger of electric shock. Others, such as Prof. Georg Wilhelm Richmann in Russia, were indeed electrocuted during the months following Franklin's experiment.
In his writings, Franklin indicates that he was aware of the dangers and offered alternative ways to demonstrate that lightning was electrical, as shown by his use of the concept of electrical ground. If Franklin did perform this experiment, he may not have done it in the way that is often described—flying the kite and waiting to be struck by lightning—as it would have been dangerous. Instead he used the kite to collect some electric charge from a storm cloud, which implied that lightning was electrical. On October 19 in a letter to England with directions for repeating the experiment, Franklin wrote:
When rain has wet the kite twine so that it can conduct the electric fire freely, you will find it streams out plentifully from the key at the approach of your knuckle, and with this key a phial, or Leyden jar, may be charged: and from electric fire thus obtained spirits may be kindled, and all other electric experiments [may be] performed which are usually done by the help of a rubber glass globe or tube; and therefore the sameness of the electrical matter with that of lightening completely demonstrated.
Franklin's electrical experiments led to his invention of the lightning rod. He noted that conductors with a sharp rather than a smooth point could discharge silently, and at a far greater distance. He surmised that this could help protect buildings from lightning by attaching "upright Rods of Iron, made sharp as a Needle and gilt to prevent Rusting, and from the Foot of those Rods a Wire down the outside of the Building into the Ground; ... Would not these pointed Rods probably draw the Electrical Fire silently out of a Cloud before it came nigh enough to strike, and thereby secure us from that most sudden and terrible Mischief!" Following a series of experiments on Franklin's own house, lightning rods were installed on the Academy of Philadelphia (later the University of Pennsylvania) and the Pennsylvania State House (later Independence Hall) in 1752.
In recognition of his work with electricity, Franklin received the Royal Society's Copley Medal in 1753, and in 1756 he became one of the few 18th-century Americans elected as a Fellow of the Society. He received honorary degrees from Harvard and Yale universities (his first). The cgs unit of electric charge has been named after him: one franklin (Fr) is equal to one statcoulomb.>>
