...contributors to modern-day meteorology. It was through his extensive research in the general circulations, that modern day weather forecasting has emerged to what it has become today. Rossby had a well-established career in the geosciences, with a broad educational background. It wasn’t until later in his life did he come to publish his greatest works. Rossby published three works in the late 1930’s and early 1940’s that involve potential vorticity, which would help establish the ground work for his most famous work on Rossby waves. The 1936 paper shows the conservation of potential vorticity in a hydrostatic, shallow fluid state, while the 1938 paper is an extension to the highly stratified hydrostatic flow, this time using isentropic coordinates. The term potential vorticity is actually never used until the 1940 paper where it is introduced. The 1939 work by Rossby is considered by some the most famous work contributed by Rossby, as he explains the semipermanent centers of action which would become the well-known Rossby waves. INTRODUCTION When people think of meteorology, the first names to appear are John Dalton, Gabriel Fahrenheit, William Ferrel, and Anders Celsius. These men are the founders of modern meteorology and made tremendous contributions to the field. These names appear in many text books and are known throughout the world. However one such name that is only known in the science of Meteorology and not so much outside is...

...generations. A stand-alone view of various phenomena will not serve any purpose as any independent model is unable to sustain the variability of the complexities involved in the earth and ocean sciences, which are gradually converging. It has therefore become imperative to understand the interdependence and coupling of geological sciences and oceanography. The combined approach to earth and ocean sciences is also the key to predicting and managing natural disasters or hazards like earthquakes, cyclones, floods, tsunami, etc. In this context, in a significant development in India, a Ministry of Earth Sciences (MoES) was formed in July 2006 by restructuring the former Ministry of Ocean Development. The MoES deals with matters relating to meteorology, seismology, climate and environmental science and related earth sciences including ocean science and technology. It facilitates an integrated view of earth systems viz., ocean, atmosphere and land to provide best possible services in respect of ocean resources, ocean state, monsoon, cyclone, earthquake, tsunami, climate change, etc. The MoES oversees research in earth system sciences, forecast monsoons and other climate parameters, ocean state, earthquakes, tsunamis and earth science phenomena. The ministry also supports industry in science, aviation, water resources, aquaculture, agriculture, etc., by disseminating weather information. It also develops and coordinates science and technology related to oceans, Polar Regions besides...

...Very heavy rain fell in storms close to the village, causing two rivers to burst their banks. About two billion litres of water then rushed down the valley straight into Boscastle. Residents had little time to react. Cars were swept out to sea, buildings were badly damaged and people had to act quickly to survive. Fortunately, nobody died - thanks largely to a huge rescue operation involving helicopters - but there was millions of pounds worth of damage. In pictures Slide show of photographs of the Boscastle flood. Enlarge and Play Map of the area affected. Physical Impacts Flooding On the day of the flood, about 75mm of rain fell in two hours - the same amount that normally falls in the whole of August. Huge amounts of water from this sudden downpour flowed into two rivers, the Valency and Jordan (which flows into the Valency just above Boscastle). Both overflowed, and this caused a sudden rush of water to speed down the Valency - which runs through the middle of Boscastle. Destruction of houses, businesses and gardens Floodwater gushed into houses, shops and pubs. Cars, walls and even bridges were washed away. The church was filled with six feet of mud and water. Trees were uprooted and swept into peoples' gardens. The weight of water eroded river banks, damaged gardens and pavements. Human Impacts There was a huge financial cost to the floods. This included: * the rescue operation - involving helicopters, lifeboats, and the fire service. * the loss of 50 cars ...

I have the tendency to make conversation with co-workers and customers about the following areas of news, which include: weather forecasts, sports, world issues, breaking news, and the latest news coverage that takes place in Miami. I have acquired the habit of watching the daily news with my mom every night and logging into NY Times during work hours just to browse current news and read the most recent articles as a form of entertainment. There’s no doubt that reading news articles’ on the web can be slightly addicting and is interference. Also, the news apps on your smartphone are a near constant distraction. I found myself not being able to respond to simple questions regarding the weather forecast, or anything sports related for the next couple of days. I form more casually based relationships at work due to the fact that conversation is very monotone and usually news related. You tend to become impersonal and reserved in your communication pattern towards specific individuals when you just speak about broad topics or community based issues. As if you can distinguish the difference between being acquainted with someone and establishing a friendship. I’m usually subjected to watching ESPN in addition to the daily news at my home...

...Weather Radio Distribution and Education Project On July 2nd of 1997, severe storms and tornadoes tore through Wayne County Michigan. Throughout the course of the storm 90 people were injured and there was a damage cost of $90 million. Based on the repercussion of this storm alone, the county felt a mitigation system was needed to help protect its 2 million residents. To help reduce the effects of storms the county chose to start a weather radio distribution and education project in 1998. This weather radio mitigation project installed national oceanic and atmospheric administration weather radios in every school, hospital, and nursing care facility in the county. This totaled 860 radios throughout these facilities. Included in the mitigation process was an education/training program. Employees of these facilities learned how to plan and prepare for severe weather. This day of education/training was video taped to share with other county facilities and to be used as a state wide example. Also, the mitigation process was funded by the HMGP and the local community. The total cost of installing radios and the education/training day was $21,000. This mitigation program is great to help our children, the sick, and elderly during severe storms. The radio system will give schools, hospitals, nursing care facilities a better warning system for severe storms. This warning system will increase warning time and give employees adequate time to follow through with their severe...

...Tools for managing weather risk Characterization Weather derivatives, unlike the financial and stock are used to hedge quantity rather than price risks. As commodity futures have underlying price of the commodity and weather derivatives are based on a measured weather index, depending on the specifics of the contract. For this purpose, relevant weather variables can be measured quantitatively. Most weather contracts – 69% Degree Days are based on indices which measure the deviation of the average daily temperature from a base temperature (mostly 65 ° F or 18 ° C). These indices occur within the energy industry and are designed to correlate well with the consumption of electricity for heating (Heating Degree Days, HDD) or cooling (Cooling Degree Days, CDD). The indices are calculated for each day of the contract and in effect a measure of how cold (HDD) or how warm (CDD) is one day. The index value for the contract period is the cumulative sum of the measured daily deviations from the benchmark. The same principles of aggregation of reported daily values (deviation from a benchmark average and cumulative value) is applied to calculate indexes based on the amount of rain and snow, wind power, etc.. Specific type of indexes are indexes threshold ("event" or called "critical day" index), which report the number of cases (of days) during the contract, which occur in certain weather events, such as average daily temperature exceeds (or falls below) threshold. Types of derivatives ...

...Sibrey McManus April 13, 2013 GEO 111-20 Homework #6 The Great Drying Strikes Again Global warming has been a controversy for many years now. It wasn’t until this past summer that seemed to change the minds of those doubtful individuals. Although the issue shy’s away in presidential campaigns, it is still an alive and well concern for scientists and the whole of society. Bryan Walsh’s article in Time Magazine, The Great Drying Strikes Again, elaborates on last summers events that point towards the reality of global warming. The extended dry spell and the record-breaking high temperatures increased the number of Americans that say they believe in global warming from 70% compared to 58% just two years ago. Agricultural states like Illinois, Iowa, and western Indiana had less than half the normal amount of rain over a 30 day period, and the extended dry weather critically hurt production. This unusual drought struck the interest of scientists to use geochemical indicators to revel precipitation levels thousands of years ago to forecast the past of the American West. Researches found through lake sediment cores from the Valles Caldera in northern New Mexico, that southwest America experienced a dramatic climate change during the warm periods of the Pleistocene Epoch, which lasted from 2.5 Million years ago to 11,700 years ago. Another group of scientists researched tree-rings to find evidence of a series of severe droughts that in occurred in the Plaines and the Southwest...

...Tornado warning forecasts in the 1880s and 1890s were more harmful than beneficial to the public (Coleman et al. 2011). The public was not aware of the safety procedures that prevented unnecessary fatuities and injuries due to reckless behavior. The impulsive, reckless behavior caused tornado warnings to be banned in 1887, however, the Civilian US Weather Bureau (USWB) lifted the ban in 1938 (Coleman et al. 2011). The USWB was the first warning system that informed the public of severe weather development information, and safety information. In the World War II era, storm spotting was only used to protect military bases from severe weather, and then became a public service in 1948 by the Air Force’s Fawbush and Miller (Doswell et al....

...The weather is an every day natural occurrence we don’t have to think, talk, or act on it because it does what natural occurrences do best, simply exist. I am very well versed in the ways of weather, and how it can affect the world. Though, I Edward Swartze have a very unique case when it comes to how my life has been affected by the weather. So, let me start from the very beginning on December 25, 1999 in a town called Covington, Georgia. The clouds were a dark and metallic gray flowing with the winds that rose at a speed so fast nothing could protect you from the cold it created. Yet, still here in the bright white, Covington Hospital a baby boy was born. The baby of course wasn’t wanted, and was sent into the relentless system of foster care. The foster parents' names were David and Leah Swartze. Mister Swartze was a large, and cumbersome man who looked very similar to an old Elvis Presley. His hair was always a slicked back helmet, and his arms where always unshaved steel contraptions. Though, his wife Miss Swartze never could ask for more. Miss Swartze was a soft and gentle woman who was as dainty and fragile as a teacup made of china. Her appearance gave her an impish, and fairy like look that was rare when it comes to people. The couple was glad when they received him on a bright and sunny Tuesday morning in December. They held the child as soon as they were able, and stared into his deep blue-gray eyes. The boy grew older, and golden brown curls sprouted from his childish...

...The objective of lab eight was to describe the fronts there are on different types of maps. II. Methods: The materials that we used for lab eight was four different websites and our textbook. The first website was http://www.state.nj.us/dep/seeds/wssym.htm and we used this to help us read the different types of symbols that were on the maps. http://weather.uwyo.edu/surface/front.html was used to look at the map that had fonts of the day. http://weather.rap.ucar.edu/surface/ we used this website to look at weather symbols of a specific area from the previous map. The last website was http://earth.nullschool.net where we looked at the flow of the air on the map. I used my book to learn how to read a station model. All of the things that were used for this lab were very important in order to get it done. III. Results: The map that is below has all different kinds of fronts that are happening all over the United States. There are many clod and warm fronts, we also have a few stationary fronts that are across the map in many different locations. The first front that I notice was a long cold front that starts in New Mexico and traveled all the way up to Canada. The Pacific Ocean has a stationary and warm front happening in between Oregon and California. There is a cold front that starts in North Carolina and travels out to the Atlantic Ocean. In the Atlantic Ocean also has a warm front that is happening. In Canada there is a little stationary front and a long cold front that formed...

...Problems at JetBlue Debate Stephanie Benson XBIS/219 August 23, 2013 Richard Wallace Problems at JetBlue Debate I think that some things that contributed to the meltdown at JetBlue was how disorganized they were without knowing it. It seemed the decision they had made to wait for the weather to get better was made because they wanted to be known as the best. But instead it ended in failure because the more time they waited for the weather to clear the worse the weather kept getting. In this time period it brought in more people hoping to catch a flight with JetBlue since they remained open without canceling any flights. This added to the chaos by building up the hopes of people trying to get to their destinations. When this didn’t happen they had a lot of angry people and no backup plan in place. Since New York has always had this type of weather during the winter season I would have made sure there was a plan in place in case we had to cancel flights. I would plan for the worst and if didn’t happen than at least we would have been prepared. If weather worsened to the point that it started to freeze than I would have started cancelling flights slowly so we wouldn’t be bombarded all at once with people trying to call and cancel. Having some type of system in place for people to cancel online would have been my first priority and I would put this plan in place way before something like this ever had a chance of happening. I think this plan should have been put...
