‘Low pressure atmospheric systems have more of a short term impact than high pressure systems.’ Discuss. Low pressure atmospheric systems are also known as depressions or cyclones and they form in mid- and high-latitudes. They are formed by the mixing of cold and warm air, the warm air is lighter, so it rises above the denser, cold air and forms a centre of low pressure. High pressure atmospheric systems are also known as anticyclones and have very different characteristics to depressions. Anticyclones are large masses of subsiding air, which produces high pressure at the surface. There are a variety of difference between anticyclones and depressions, including the weather conditions, the length of time they last and the impact they …show more content…
The impacts of anticyclones and depressions vary, as does the period they remain and the effect they have. The North American blizzard of 2003 lasted for five days throughout February and occurred on the East Coast of the USA and Canada. It was a record-breaking blizzard, which caused 27 deaths and over $14 million worth of damage. The cities in America were bought to a standstill, as there was a range of 38-76cm of snow covering the ground. The cause for such an unusually extreme blizzard was the fact that the conditions were favourable, with moisture from the Atlantic Ocean enhancing precipitation and a high pressure system over Canada, allowing cold air to be brought down coastal areas. This meant that the precipitation was mainly snow, hence the record-breaking statistics. The effects this storm had were mainly short-term, but the roof of the historic Railroad Museum collapsed and 27 people lost their lives. Additionally, transport infrastructure was brought to a halt, and three major airports were also closed.
So, the impacts of depressions are mainly short-term, although the destruction can be horrendous, whereas, anticyclones usually cause long-term impacts on a country such as the Drought in Britain and Europe in 2003. This drought effected many locations, but the main focus was on the UK, France and Portugal. Not all impacts are negative, as the heat wave did boost the tourist industry in most countries and sales for summer items such as
On January 12, 1888, the weather in the west was mild, compared to previous weeks. Little did the people know that a massive cold front was in route and would be catastrophic to the people, their livestock, and the economy in the dekota and nebraska praries. The cold front would cause one of the worst blizzards for the region, killing close to 500 people. The factors that made the death toll so high involve the mild weather before the storm, the lack of technology for warning systems, and bad timing.
Mother Nature can form many powerful storms, such as hurricanes, blizzards, typhoons, and cyclones. However, the two storms that are significant to the New England area are hurricanes and blizzards due to their extremely powerful type of weather. Hurricanes and blizzards can be catastrophic and cause excessive damage, however under different conditions. Blizzards involve large mass amounts of snow covering a wide area, while a hurricane involves excessive rain and tremendous winds. Both storms are quite different; however, there are a few similarities. A hurricane is characterized by thunderstorms, strong winds, and heavy rains. A blizzard is a storm with dry, strong winds, and intense cold. Blizzards and hurricanes are two natural phenomena that make an interesting comparison and contrast in how they are formed and how disastrous they can be.
Also the amount of air molecules is greater at lower altitudes than at a high altitude. If an air molecule hits another air molecule even more air pressure happens. Air pressure can be felt while riding an express elevator to the top floor of a really tall building. Also it can be felt by diving all the way to the bottom of a swimming pool. The air pressure can also be formed when there is a lot of wind which causes the air molecules in the air to move around even faster and crash into each other even more.
The Blizzard of 1888 tested how much the human spirit could take. Stacking problems on problems, it was unforgiving to everybody in the area. Though the immigrants who came to the US all took different paths and ended up settling in different places of the Great Plains, in the end they both went through the same cold, unpredictable blizzard.
According to the forecasters only about 12 inches of actual snow fell. Their assumptions on the rest of the snow is it blew from Lake Erie to the sounding locations. Snow was recorded in areas up to 100 inches deep (usatoday.com). This varied some from location to location but all the surrounding areas were hit hard. Most areas only see this amount over weeks or months. Most of the snow accumulated in several hours up to a few days. Never had snow crews seen this much in such a short period of time. Due to the large amount of snow it left many motorists stranded. A large portion of the death tolls from this storm came from people stranded in their vehicle. Once there vehicles were stuck there only means of heat was from the vehicle running. In some cases the vehicles ran out of gas and in some they broke
Contrary to popular belief, the Great Depression went beyond the shore of the United States and had a major impact on multiple countries. All countries involved in trade with the United States were greatly affected- one of these being Germany. When our stock market crashed, the production of various products were put to an abrupt hault. Without the necessary money and supplies to manufacture products, there was no way to do so. Then, this resulted in the loss of jobs by many factory workers bringing the unemployment rate in the US to a mind-boggling 24.75% in 1933.
The drought killed the remaining plants and crops leaving nothing behind to anchor the dirt to the ground. As winds began to rise they ripped away the topsoil, exposed from bad farming practices, from the Earth; and by 1934 more than 35 million acres of farmland became sterile and useless and another 125 acres of topsoil were being rapidly drained. Large dust storms called “Black Blizzards” would originate in the Dust Bowl states and make its way to the East Coast as far as New York City, Washington D.C., and covered ships in the Atlantic Ocean with dust. Some were as large as 2 miles high traveling more than 2000 miles such as the one that occurred on May 11, 1934. The worst of the Black Blizzards came on April 14, 1935 with wind speeds up to 100 miles per hour carrying over 3 million tons of topsoil with it (Blakemore). The storm turned the skies black frightening people across the Midwest and East Coast. One observer said, it was like “the Red Sea closing in on the Israel children… it got so dark that you couldn’t see your hand before your face, you couldn’t see anybody in the room”. The stormed ended up destroying fields and causing car accidents and several people were left blind or with pneumonia.
Thesis: The Children’s Blizzard of January 12, 1888 was the worst blizzard to experience from the Dakotas to south Texas of all the damage from the winds and the snow, the amount of people that died,and the buildings destroyed. So many children died so that's why the name of the blizzard the Children’s Blizzard.
2. The depression lasted from 1930 to 1941, and it impacted the poor, such as delaying marriages, dropping the birth rate and many children became sick and ill. However on the other hand the wealth were not as affected because they could afford more of a loss with their crops.
The Great Blizzard of 88’ is one of the worst blizzards in America. It led in the death of almost 200 people in New York City, and the blizzard also affected Keene, New Hampshire, New Haven, Connecticut,
On March 12, 1993, one of the most disastrous blizzards of all time hit Canada, United States, and Cuba, resulting in more than 300 deaths , more than 7 billion dollars in damage, and electricity loss for millions of families. Even though more than a decade has passed since the superstorm, it remains nicknamed the Storm of the Century. However, because of technological inventions and advancements, preparing for a blizzard today is much easier then 25 years ago. Some preparations remain the same while many are different, with the overall severity decreasing.
Business, consumers and employees are more weak to downturns in the economies of trading partners. For example, recession in the USA leads to decrease in demand for UK’s exports, leading to falling in export incomes, lower GDP and incomes, decrease in domestic demand and rising in unemployment.
Ans: There was a snowstorm on Saturday, January 2nd, which was very serious and caused over 10 inches of snowfall. Northwest Airlines had been too late to halt the departure of their planes from other cities to Detroit, on of its largest hub. They made the decision to let 30 planes land in Detroit on Sunday, neglecting those 14 inches of snow and the severe weather condition. Luckily, all the planes were landed successfully without any major accidents or disasters. However, the planes had to sit on the tarmac for over 8 hours before they could deplane their passengers. All the food, water and drinks were used up
The United States releases twenty tons of carbon monoxide per person per year. Carbon Monoxide release is a result of burning fossil fuels with an insufficient amount of oxygen that causes the formation of carbon monoxide that pollutes our environment. Everyday fuel is burnt by cars, airplanes, large factories and manufacturing plants. This is causing a very large and deadly problem for our environment. When gases used on earth are released into the atmosphere they act as a blanket and trap radiation that is then redirected to earth. This concept is called the Greenhouse Effect (Bad Greenhouse, 1).
During the past few decades, atmospheric pressure low-temperature plasmas have attracted much attention as they have enormous application potential from plasma processing to biomedicine and aerospace. (-- removed HTML --) (-- removed HTML --) 1 (-- removed HTML --) (-- removed HTML --) A popular method to generate this kind of plasma in atmospheric air is the dielectric barrier discharge (DBD), which combines the advantages of non-equilibrium plasmas with atmospheric pressure operation. Usually, DBD at atmospheric pressure is driven by the alternating-voltage, with the frequency ranging from a few tens of Hz to several kHz. Filamentary discharge is the most common DBD mode in atmospheric air (-- removed HTML --) (-- removed HTML --) 2
