On August 2, 1985, Delta Air Lines (Delta) flight 191 was a regularly scheduled passenger flight between Fort Lauderdale, Florida, and Los Angeles, California, with an enroute stop at the Dallas/Fort Worth International Airport, Texas (DFW Airport). Flight 191, a Lockheed L-1011-385-1 airplane, departed Fort Lauderdale on an instrument flight rules (IFR) flight plan with 152 passengers and a crew of 11 on board at 1510 eastern daylight time. The DFW Airport terminal weather forecast contained in the flight crew’s dispatch document package stated, in part, that there was a possibility of widely scattered rain showers and thunderstorms, becoming isolated after 2000 central daylight time. The dispatch package also contained company Metro Alert No. T87, valid to 2100, which stated that “an area of isolated thunderstorms is expected over Oklahoma and northern and northeastern Texas, a few isolated tops to above …show more content…
The 1900 NWS surface analysis chart showed a weak diffuse cold front about 60 NM north of the DFW Airport. The 1600 NWS surface analysis weather chart issued by the National Meteorological Center, Camp Springs, Maryland, showed a weak diffuse stationary front about 60 NM north of the DFW Airport. There were no SIGMETS, 14/ convective SIGMETs 15/, Severe Weather Warnings, Local Aviation Warnings, or Severe Weather Watches, in effect for the time and area of the accident, according to the NTSB post-accident report.
The Weather at DFW Airport said, “On final approach to runway 17L at DFW Airport, flight 191 penetrated a weather cell containing a thunderstorm with a heavy rain shower.” Because of the evidence that two weather cells (Cells “C” and “D”) were present north of runway 17L, the Safety Board examined the possibility that Cell “C” might have masked Cell “D” from flight 191s flight
In conclusion, the deadliest and most devastating U.S. tornado outbreak of the 20th century was the April 3–4, 1974, “Super Tornado Outbreak.” It lasted 16 hours and at least 148 twisters tore up 2,500 miles of Earth through 13 states over a 24-hour period, according to the National Weather Service. The "super outbreak," as meteorologists now call it, left 330 people dead and 5,484 injured. Property losses were placed at $600 million and only ten of the thirteen states that were hit, were declared a disaster area.
Charles Lindbergh had an impact to the 1930’s. Here’s a couple facts you didn’t know about him.
The swiftness, beauty, and absolute daunting sight of tornadoes have haunted minds and pulled at the curiosity of many. As Mother Nature’s fiercest windstorms, tornadoes do not simply lift you up and transport you to the magical Land of Oz. Rather, they habitually throw you around like a rag doll leaving a disaster behind them. Interestingly enough, tornadoes are yet to be fully understood. We know what a tornado is and how it forms but why it forms under various circumstances and not others is still under scrutiny.

This was very evident last week. The weather report was calling for overnight temperatures to be in the low twenties accompanied by rain. The low temperatures and rain were going to become a big headache for the Texas Department of Public Safety, otherwise known as DPS. Many of our highways are elevat...
In the book Flight #116 is Down Caroline B. Cooney, Heidi saw a plane crash in her yard. She was shocked to see what happen. Heidi knew she had to help all the people in the plane so She ran inside to call 911. First, Heidi helped by Letting all the hurt passengers to stay in her house and keep warm. Heidi was brave enough to lend her house to save them. Next, Heidi Was giving coats to all the hurt people that the hero's Couldn't help. Heidi gave coats to the people with not so severe injuries because they needed to stay warm because they were gonna be down there the longest. Lastly, Heidi helped a toddler that was in the cold and could die but Heidi had helped the toddler get in the house and stay alive. Finally, Heidi had helped people
The first type of thunderstorm is a single cell storm which is nothing more than an updraft and a downdraft working together to create weather. Single-cell thunderstorms usually pop up out of the blue and only last for a short period of time. Because of the short life span associated with this type of storm they are sometime referred to as a “pulse storm” (1998, Texas weather network). Single cell storms are usually not well formed and happen at random times, which makes them hard to forecast when and where severe weather will occur (n.d., Singlecell Thunderstorms). While a single cell storm only lasts for a short period of time, they are still capable of producing severe weather. Due to the unpredictability of these types of storms the microburst threat to aviation is very serious (n.d., Singlecell Thunderstorms).
Shipping companies and shipbuilders worked with insurers and mariners for safer ship designs with greater stability and more longitudinal strength. The storm proved the Great Lake straight deckers were underpowered. Many complaints were directed toward the Weather Bureau of the U.S. Department of Agriculture. This resulted in an increased effort to achieve more accurate weather forecasting and faster communication of storm warnings.

Dr. Isaac M. Cline was the chief of the U.S. weather Bureau's Galveston station located on the 3rd floor of the Levy Building which can still be found on the corner of Market and 23rd. Cline had begun tracking the storm from the Cape Verde Basin off the western coast of Africa. On August 31, this storm entered the Caribbean and began to increase in size. The hurricane passed just north of Cuba, and on Thursday September 6 entered the Gulf of Mexico. The projected course would have the storm make landfall well east of Galveston, but on Friday Dr. Cline became worried.
The 25th of September proved to be a tragic day in the legacy of Big Island Air. The final report from the NTSB included that the likely cause of the accident was the pilot’s poor decision to fly into known instrument meteorological conditions of the cloud covered terrain. The final report also concluded that the pilot’s failure to navigate properly and a direct disregard for standard operation procedures were all contributing factors. The pilot’s blatant disregard for flying into instrument meteorological conditions while operating under VFR rules and failing to ever obtain a weather brief all played a major role in this tragic disaster.
The flight had come in from Van Nuys Airport (VNY), Van Nuys, California. Witnesses recall that the plane had landed and parked at the FBO to receive some fuel. The plane had sat on the ramp for approximately 45 minutes before it took off again. While on the ramp, numerous witnesses recalled snow falling and “contaminating” the wings of the planes. Before the plane had taken off, witnesses said that they did not see either of the pilots inspect the wings for icing conditions and snow buildup. The METAR for the airport was, “wind calm, visibility 1 ¼ miles in light snow and mist, few clouds at 500 feet, overcast at 900 feet, temperature 1°C and dew point -2°C.”(Insert here) The cockpit voice recorder (CVR) recorded the captain asking the pilot, “How do you see the wings.” The first officer replied, “Good.” And the captain said back, “Looks clear to me”.(Insert here) The captain turned on the engine bleeds which help keep icing conditions down. A downfall with engine bleeds is that they reduce the take off distance. The captain then proc...
This hurricane was a surprise to everyone. One junior forecaster tracked the exact storm but nobody else listened to him because he was a junior forecaster. The rest of the forecasters did not track the hurricane correctly therefore no one was prepared for the storm. No warnings were put out about the hurricane and
Jackie Johnson said of the weather channel stated “People of Kansas City and cities northeast from here, take shelter immediately. People on military bases, stay on the bases and take shelter.” When I heard this, I gathered my family and my pets, and we went down to the storm cellar. A few hours later the tornado was ripping the house apart, I heard the glass breaking, and the wind sounded like a freight train going by. I had questions in my head as the tornado was going by like: Why was a women forecasting the weather? What is going to happen to my family? Why did Jackie say military bases?
...s for one week, using a local source, Mr. David Aldrich from WVLT-TV Channel Eight, Knoxville, Tennessee, and one that we have never used before, the National Weather Service predictions for Knoxville, Tennessee. I was then to record the actual weather for each day tracked. Afterwards, I addressed the accuracy of Mr. Aldrich’s predictions versus the National Weather Service. Overall, this essay examined the questions of weather, climate, weather predictions and accuracy for the purposes of this lab.
