In a movie filled with memorable quotes, one of the shortest and simplest might have been “It’s a Twister!”, but it was part of a tornado scene that is still considered to be a classic more than eight decades later. August 25, 1939 was the official release date of the “Wizard of Oz" which was the first movie to depict an authentic looking tornado using improbable “1930’s style” special effects. Through the decades, this all-time classic has inspired movie-goers and “weather weenies” alike with the scene of a twister lifting Dorothy’s home into the sky over rural Kansas farm land. This has become the time of the year in which many cable TV stations air this classic movie for new viewers who have never enjoyed it and for all of the old-timers out there who can watch it year after year after year (TBS, Saturday evening, November 18th, 6:30PM and again at 8:30PM).

Forty-eight years have passed since a major storm over the Great Lakes helped to sink the SS Edmund Fitzgerald on Lake Superior taking the lives of all 29 crew members on November 10th, 1975. When launched on June 7, 1958, it was the largest ship on North America's Great Lakes, and to this day she remains the largest to have sunk there. The Edmund Fitzgerald was in the worst possible location during the worst weather of the ferocious storm. The wind and waves from the west hit the freighter broadside as it tried to flee south to safety in Whitefish Bay. The Edmund Fitzgerald was loaded with about 26,000 tons of taconite pellets on November 9th, 1975, at Superior, Wisconsin and was bound for Detroit, Michigan when the storm hit.

Rapid changes in weather can be experienced in the northeastern US during the latter stages of October as to the west, cold Canadian air masses begin to regularly drop from Canada into the Northern Plains/Upper Midwest and to the east, the Atlantic Ocean remains relatively warm as it loses its stored summer heat more slowly than the continent. In fact, hurricanes can still form over the still relatively warm waters of the Atlantic Ocean and the contrast between the increasingly frequent cold air masses to the west and the warmth to the east often results in powerful storms just offshore. In late October 1991, several ingredients converged to create an immensely powerful storm that took on a few names including “The Halloween Nor’easter” or the “Unnamed Hurricane”. The most well-known name for this storm, however, is “The Perfect Storm” with a book and subsequent film of the same name.

The World Series begins tonight in Arlington, Texas between the Texas Rangers and Arizona Diamondbacks and there is the threat of showers and thunderstorms. Indeed, the weather has had a big impact on some World Series games in recent history from biting cold and snow to rain and extreme heat. However, this year, both participants have retractable roof stadiums so the weather should not be an issue. The World Series can end this year as late as November 4th if all 7 games are required and - with the recently added extra playoff round - a November finish to the baseball season is going to be more common and the weather can certainly be impactful.

Galileo turned his primitive telescope towards Jupiter in the early 1600’s and saw tiny specks of light with no discernable features. What a difference 400+ years can make as today’s backyard telescopes can resolve Europa’s disk surprisingly well. Europa is now considered one of the most complex and fascinating worlds in the solar system. Cracks, ridges, and chaotic terrain on the moon's icy crust may offer access to one of the largest oceans in the solar system--and a possible abode for aquatic life. NASA's Europa Clipper spacecraft, due to launch one year from now in October 2024, will conduct a detailed reconnaissance of the moon's surface to help plan future missions including a lander and perhaps even a submarine.

In August of 2017 America went crazy for the first coast-to-coast total solar eclipse on US soil since 1918 and it provided a great opportunity for scientists and all sky watchers. What was referred to as “The Great American Solar Eclipse” took place on August 21st, 2017 when the moon passed between the sun and earth. Total solar eclipses occur somewhere on Earth every year or so, but generally cast their shadows over oceans or remote land masses. If you missed the 2017 total solar eclipse or it turned out to be cloudy in your particular area then there will be another opportunity in just about six months from now on Monday, April 8th, 2024. This time the Moon's dark shadow, about 115 miles wide, will cross Mexico, sweep northeast from Texas to Maine, and then darken the Canadian Maritimes.

On September 21, 1938, one of the most destructive and powerful hurricanes in recorded history struck Long Island and Southern New England. Little media attention was given to the powerful hurricane while it was out at sea as Europe was on the brink of war and was the overriding story of the time. There was no advanced meteorological technology such as radar or satellite imagery to warn of the storm’s approach.
This storm has taken on a few names over the years including “The Great New England Hurricane of 1938", "The Long Island Express", and the "Yankee Clipper". It was the first “major” hurricane to strike New England since the year 1869. In the long period after this storm, New England was directly hit by a hurricane on an average of once every 6.7 years until 1991 - and there have been none since.

At the end of the 19th century, America was beaming with confidence and feeling bigger and stronger than ever before. The city of Galveston, Texas was booming with a population of 37,000 residents on the east end of Galveston Island which runs about thirty miles in length and anywhere from one and a half to three miles in width. Its position on the harbor of Galveston Bay along the Gulf of Mexico made it the center of trade and the biggest city in Texas in the year 1900. A quarter of a century earlier, a nearby town was destroyed by a powerful hurricane and this object lesson was heeded by many Galveston residents and talks of a seawall to protect the city were quite prevalent. However, no seawall was built and sand dunes along the shore were actually cut down to fill low areas in the city, removing what little barrier there was to the Gulf of Mexico. This proved to be a fatal mistake for the city of Galveston in what nobody could foresee happening to this magical place that seemed destined to become the New York of the Gulf of Mexico.

On September 1st, 1859, a ferocious solar storm took place that impacted much of the planet. This ferocious solar storm is now known as the “Carrington Event”, named after the British astronomer, Richard Carrington, who witnessed the largest solar flare from his own private observatory which caused a major coronal mass ejection (CME) to travel directly toward Earth. Recent studies of solar storms have warned that these type of “Carrington Events” may not be quite as rare as once thought (e.g., Hayakawa et al). Many previous studies leaned heavily on Western Hemisphere accounts, omitting data from the Eastern Hemisphere. A super storm of the same magnitude as the “Carrington Event” in today’s world would very likely have a much more damaging impact than it did in the 19th century potentially causing widespread power outages along with disruptions to navigation, air travel, banking, and all forms of digital communication.

It was shortly after noon on August 24th in the year 79 A.D. and Mount Vesuvius sent a tall cloud of steam and ash high up into the atmosphere. The ancient Roman town of Pompeii near modern day Naples was soon covered in complete darkness and the thickness of the falling debris increased by about 6 to 8 inches per hour. The rocks which comprised the debris were up to 3 inches in diameter and fell with a speed of up to 100 miles/hour. This first phase of the eruption led to casualties primarily caused by roof collapses. After 12 hours of continuous explosive activity, the second phase of the eruption began and it was characterized by substantial flow of lava down the sloping Mount Vesuvius and this caused additional deaths and destruction. In fact, the eruption of Mount Vesuvius spewed 1.5 million tons of lava per second into Pompeii and surrounding towns. In a short period of time, an estimated 15 to 20 percent of Pompeii’s population died (about two thousand people), the small towns of Herculaneum, Oplonti and Stabiae were destroyed, and Pompeii was changed forever.
